[birds chirping]
[soft music playing]
[dogs barking in the distance]
[narrator] We think we know what's going on inside the mind of a dog.
But new discoveries suggest we may not know the whole story.
Dogs have found their way into every corner of our lives.
[camera clicks]
-[host] There he is. -[woman] Hi, baby!
[host] Hi! Hi, Toulouse.
-[narrator] They're our companions. -Good dog.
-[narrator] Our saviors. -Here, Lassie, take it to Gramps.
[Lassie barks]
[narrator] Our pop-culture icons.
Peter, you hear that?
[howls]
Scooby-Doo!
[narrator] And yet we're only beginning to understand
how their brains actually work.
[woman 1] For a long time, scientists felt
like dogs weren't really worthy of scientific study.
But now, canine science is really blossoming.
[woman 2] Puppy! Look!
[man] That big aha moment happened
when people started using methods that had been developed to use with kids…
[bell rings]
[man] …to uncover and unlock the secrets of the dog social world.
-[bell rings] -Bravissimo!
[narrator] So how did dogs and humans become so hopelessly intertwined?
[all gushing]
[woman 3] I do think my dog loves me,
and I think there is scientific evidence to back that up.
[automated voice]
[narrator] New science is helping to decode their strange behavior,
decipher their hidden language…
[howling and barking]
[narrator] …and discover why dogs are the way they are.
[man] Understanding the mind of dogs is really an incredibly useful thing,
not just to enrich our relationships with them,
but to understand ourselves better.
[narrator] We can all get closer to our dogs
if we know their secrets.
[uplifting music playing]
[music fades]
[puppies grunting]
[narrator] Dogs are the single most diverse animal to ever walk the earth.
[man] Given how different dogs look from one another,
you can imagine that if an alien from another planet landed,
it could be confused.
[dog whimpers]
It would be really easy to think that a Chihuahua and a Great Dane
are completely different things.
The history of where dog breeds come from is really fascinating.
[panting]
There are breeds that were bred originally in Asia,
Africa, or the Americas.
Most of the breeds that we recognize today
are gonna be 100, 125 years old.
[narrator] Until the late 1800s, dogs were primarily bred for work,
when a new phenomenon took over the dog world.
[whimpers]
[narrator] Vanity.
[Hare] Instead of having iPhones or Louis Vuitton bags,
people started to breed dogs to communicate status.
Then other people wanted dogs of that same breed,
and they became popular.
[narrator] In Scotland, the first golden retriever
was believed to be an undesirable mutation
from a long line of bird dogs.
But the eccentric Lord Tweedmouth liked the new color
and bred him with other soft, red dogs,
creating a brand-new breed.
[dogs barking]
[narrator] For decades,
the most popular breed has been the Labrador Retriever.
But in 2022, the French bulldog surpassed the Lab in the US.
[dog whimpers]
[narrator] So how exactly did our most popular pet
become such a valuable member of the family?
To understand that, we need to start at the very beginning.
So where do dogs come from?
Whoa, that's a… fun one.
[barks]
[Hare] The scientific name of the domestic dog, our best buddies,
is Canis familiaris.
The scientific name of a wolf is Canis lupus.
[growling]
But every dog and every dog breed is just another version of a wolf
that, through selection and evolution, has expressed itself.
[narrator] Every breed shares 99.9% of the same DNA as wolves.
[wolves howling]
[Hare] Wolves were extremely successful
up until, really, 50,000 years ago.
Millions and millions and millions of wolves
spread all over Europe, Asia, and North America.
There weren't just wolves. There's what's called a carnivore guild.
-There were giant hyenas… -[howls]
-[Hare] …giant cave bears… -[roars]
-[Hare] …lions. -[growls]
[Hare] The modern human population pulses out of Africa,
and we are super predators.
[grunts]
[Hare] We're so good at hunting
that most other large predators go extinct.
[creature cries]
[Hare] Two species that do survive are brown bears…
[bear roars]
-[Hare] …and wolves. -[wolf howls]
[Hare] And so wolves are real survivors.
Okay, now it becomes a little bit more mysterious.
Instead of being afraid of humans,
a population of wolves,
they actually became attracted to all the yummy garbage
that the humans were creating.
So a new type of friendliness evolved.
[laughter]
[Hare] So survival of the friendliest
is really the most successful evolutionary strategy
that has been identified.
[dog panting]
[Hare] And it is counter to survival of the fittest.
It is not at all that being big, bad alpha makes you superior.
And, in fact, if anything, being dominant is super costly.
In any species that evolves,
a new type of friendliness that leads to new forms of cooperation
just absolutely does gangbusters in the game of life.
Whether it's flowers
that are really an evolutionary innovation in the plant world…
[buzzing]
[Hare] "I'm gonna be friendly, give you something,
and then we're gonna cooperate."
And guess what? There's only one terrestrial vertebrate
that can live year-round in Antarctica.
And it is the Emperor Penguin.
[penguins chirping]
[Hare] They do it by hugging.
They hug all winter.
So friendliness wins. It wins again and again in life.
[dog panting]
[narrator] And dogs have a special adaptation
that helps them take friendliness to the next level.
[Hare] As an example, one of the things that's changed dramatically in dogs,
relative to wolves,
is they have a muscle that allows them to pull back their eye…
[woman] Oh my God!
[Hare] …and show the white part of your eye, called the sclera.
And we know that when humans interact,
seeing white sclera is the way that our brain automatically recognizes
that you're interacting with another human being.
It's actually one of the key ways
that newborn infants recognize their mother.
Puppy dog eyes.
They really hijack one of the main ways we interact with each other.
[dog whines]
[Hare] And dogs have taken advantage of it.
[puppies yipping]
[narrator] Puppies are born blind and deaf.
But they can immediately smell their way to Mom.
After three weeks, these puppies are opening their eyes
for the very first time.
[puppies yipping]
[narrator] This litter has ten pups.
Four above average, but far from the world record of 24.
And every single one is unique.
Right down to the tip of their nose.
So dogs have nose prints in the same way that we have fingerprints.
If you were to put a little bit of ink on your dog's nose
and press it up to a piece of paper,
it would make a unique imprint
that would be different from any other dog.
[dog whimpers]
[narrator] Each puppy's personality is just as different as their nose print.
And researchers are trying to figure out why.
[Hecht] So it's been a long-standing question in science,
how much does nature matter versus how much does nurture matter?
You can never just have an impact of one or the other.
They both interact to produce the dog's individual personality.
What makes a dog the way that they are
in terms of how they interact with the world?
From the environment side,
that's everything they experience over the course of their life,
even before they're born.
[puppies grunting]
Maternal style, a topic near and dear to my heart.
So that is something that we have been studying
in the first three weeks of the puppy's life.
What we're learning is there is variation
in how much mothers interact with their puppies.
We see a range of mothers that are constantly with their puppies,
and then the more laissez-faire, hands-off mothers.
We see impacts of that affecting the puppies' problem-solving skills
and even their personalities.
What we're learning is that the mothers
that were letting the puppies figure it out on their own,
their puppies went on to become the most successful guide dogs.
A reasonable hypothesis is that, you know,
they're kind of learning to figure it out for themselves early on,
and that's serving them well in their later career.
[narrator] Understanding how a puppy thinks
is a window into the mind of all dogs.
[Bray] Hi! How are you?
You ready?
Are we gonna see what you're thinkin'?
Hi, handsome. You're so cute.
I know. I love you.
Right now, we're going to be running the pointing task,
and this is kind of the quintessential canine cognition task
that I feel like kind of put canine cognition on the map
back in the early 2000s.
Puppy, look.
We call it an object choice test.
We use our high-tech Solo cups.
So there's two hiding options.
We actually tape treats into the bottom of each of the cups,
so both options smell like food.
If they're choosing the correct cup,
it's because they're using the commutative cue that we're providing them.
And then I simply point to the one that the food is under.
Okay.
[laughter]
[Bray] Good job!
And what has been found is that dogs, in general,
are really good at following a human point…
Okay.
-Good choice. -Yes!
-Good boy! You got it! -Good boy!
…even better than our closest living relatives, the apes.
[Hare] So, as smart as our close primate relatives are,
bonobos, chimpanzees,
there's one thing they're not very good at,
which is understanding that when someone gestures to them in a helpful way,
they're trying to direct you and help. They don't really get it.
You chose the wrong one!
That's something that's really crucially important in human development.
And because human infants, 9 to 12 months of age,
we start understanding when somebody gestures or points,
to follow the direction they're pointing,
we could learn something about what they're trying to show.
Hey, lookie here. Where is it? Can you get it? Can you get the ball?
Hey! Nice job.
[Hare] You got it.
All humans can do this. It's very important to our development.
But then these close relatives can't really do that.
So that then led us to believe, um,
that maybe there's something really important that's different about dogs.
-[woman] Nice! -[Bray] Yahoo!
[narrator] This pointing test was the beginning
of a dog-science renaissance,
and it led Dr. Brian Hare
to start the Duke University Canine Cognition Center.
[woman] Okay.
[Hare] It is a center that's dedicated to understanding dog behavior, psychology,
and we're trying to learn how dogs' minds work.
[woman] Okay!
[Hare] And then we're trying to use what we learn to train them better
and have them raised to do jobs more effectively.
[narrator] When given the chance, dogs are capable of amazing things.
From tracking whales…
[reporter 1] Dio guides scientists to the whales by smelling their poop.
[narrator] …to exploring the cosmos.
[reporter 2] Liftoff.
[narrator] Even running for office.
[reporter 3] Max is a golden retriever.
-My favorite politician. -Yeah.
[reporter 3] He's won three consecutive elections
in this small, picturesque town.
[narrator] But perhaps most amazing,
dogs who devote their lives to helping people.
[Hare] What people view as a great dog today
is what service dogs have been bred and raised and trained to be
for a century.
Folks have a lot to learn from service dogs
about how they might wanna raise their own dog.
[narrator] In 1986, Charles Schulz, the creator of Snoopy,
helped build Canine Companions…
[woman cheering]
[narrator] …the world's largest service-dog school.
They raise 1,000 puppies a year
in six campuses across the country.
These puppies are eight weeks old. Time they head out into the world.
And their journey can tell us a lot about our own dogs.
[woman 1] Eight weeks is a time when puppies are at an age
where it's good for them to go and be independent.
They've been bonding with their mom, with their littermates.
It's really important that they start bonding more with people at this stage.
[woman 2] Come on, puppies! Buh-buh-buh!
-[woman 3] Puppies! -[woman 2] Come on, puppies!
[narrator] Typically, at eight weeks, puppies go to a puppy raiser,
but these four puppies are taking a special detour.
[Kennedy] So we've been working with Duke University.
We have puppies that go and stay at Duke from 8 to 20 weeks of age,
doing cognition tests repeatedly every couple of weeks throughout the time.
[whimsical jazz music plays]
[narrator] These pups are flying 2,500 miles
on a plane donated by a volunteer pilot
to attend puppy kindergarten…
[barking]
[narrator] …a part of Duke University's Canine Cognition Center.
[relaxed jazz music playing]
[ding]
-[man laughs] -[woman 1 squeals]
[woman 2] So cute!
-[man laughing] Oh my gosh. -Hello!
Oh, it's good to see you.
-Did you have a good flight? -[man] Oh my gosh.
My name is Vanessa Woods, and I run the Duke Puppy Kindergarten.
-Yeah. You do a good job. -Thank you.
-You do a really nice job. -What do you do, really?
-Uh… you know. I don't know. -[laughs]
[birds chirping]
Let's check this guy out. Okay.
Now, you've never seen this before, right?
All right.
This is really tough, even for an adult dog.
[Bray] Mm-hmm. Okay.
[Bray and Hare] Oh!
-Oh, well done. Yay. -[Woods] You'll get it the next time.
[Hare] It's hard.
Duke Puppy Kindergarten, you wanna take puppies at their most cutest.
[Hare] Don't go to the left.
[Woods] But also at their final period of rapid brain development.
And we play these sort of fun cognitive games
to see if we can come up with a cognitive profile
to predict who is most likely to make it as a service dog.
-[Hare] Trial two. Pretty good. -Good job.
-You did it. -[Hare] Quick learner.
[Woods] At the moment, it takes two years before you even know
if the dog is gonna make it.
And we can take a puppy and really run them through these tests
and say, "Okay, you know, you're definitely looking like
what we predict a service dog would be."
But other ones, you're just… you're just gonna make a great pet.
[Bray] Puppy, look.
Okay.
[Hare] We have a task called the impossible task,
and what we're seeing is that some dogs
immediately focus on trying to get food
out of a container that they previously have gotten food out of,
but we've locked it and made it impossible or really hard to get it open.
[Bray] Okay.
[Hare] Some dogs, they realize, "I can't get that thing open,"
and they immediately look up to the person,
and they start barking or, you know, making eye contact,
trying to communicate with the person.
What we've learned is
the dog that really just tries to solve the problem on its own,
those dogs tend to be really great at problems
that have to do with finding things,
like in dogs that are gonna be trained in detection work.
-[Bray] Wow. -[Woods] It's amazing!
[Hare] The dog who realizes there's a problem they can't solve
and kind of look up and ask for help in a way,
those dogs tend to be dogs that are gonna do really, really well for service
and for helping people with disabilities.
You're backwards. You can't see it from there.
You wanna go around? Come here.
[Hare] And so we've been tracking how their cognition starts to emerge.
It's not like a light bulb just comes on.
It's more like a symphony of lots of little lights.
-And-- -Christmas lights.
Yeah, they kind of blink on at different times.
Um, and maybe they're different colors. I don't know.
-Um… -Fireworks.
I like Christmas trees with colored lights.
[toy meowing tunefully]
[Hare] So some of these games we're seeing consistency,
that what we measure when they're puppies does tell us about what they do as adults.
[narrator] These puppies are in kindergarten from 8 to 20 weeks.
After that, they go to a certified puppy raiser.
[laughter]
[woman] No more food, buddy.
All done.
[cat meows]
[narrator] Puppy raisers are experienced foster parents
who raise the dogs until they're 18 months.
They're tasked with teaching these puppies the basics.
[woman] Yes!
[narrator] How to be a good dog.
[woman speaking]
[woman] Oh my God.
Hi!
[narrator] The first year and a half is the most formative time for a dog.
[Hecht] There's this folk knowledge that one human year equals seven dog years.
That's not exactly right.
Um, dogs mature very quickly early in life.
They reach sexual maturity in about six months,
but after that, their development sort of flattens out.
[narrator] At 18 months, they're young adults
and ready for service dog training school.
[indistinct chattering]
We raise and train service dogs for people with disabilities.
Service dogs change lives in more ways than you would think.
The big day that dogs come in to their first day of college,
we receive the dogs,
we say, "Hey, I'm your new trainer. Let's get to work."
-[man] Yes. -[woman] That's it. Good boy.
[narrator] In this first stage of service-dog school,
candidates undergo six months of rigorous training.
[woman] Yes. Good girl.
We start training a dog in over 40 different commands.
Touch. Yay.
Shake. 'Kay.
Give. Yes.
Clients may have mobility disabilities,
so we train very task-oriented commands.
[woman] Up. Yep.
[Hutchinson] So a dog can assist you with things
that you wouldn't normally be able to do.
Push. Yes!
Tug.
Good boy.
We serve veterans with PTSD,
so we train interactive skills, like nightmare interruptions.
Yes. Good boy, buddy.
Dogs are meant to enhance a person's life.
Good girl.
[Hutchinson] Because we do have very high standards,
only approximately half of our dogs do graduate and become a service dog.
[narrator] There are hundreds of hopeful people
waiting to be matched with a service dog.
So every dog counts.
[Hutchinson] Light. You got it. Come on, get up.
Yeah! Good boy.
Whoo!
What do you think?
Was that a good workout? Was that a good workout?
Was that a good workout? Yeah-yeah.
Wow!
So this is Bonus,
and the bonus fact about him is that
he, once upon a time, had braces because of an overbite.
Yes, he's very sweet. He is very lovey.
Bonus's favorite way of interacting is butt scratches.
This really gets him going.
He really likes the butt scratches. Right, baby?
Ohh. Yeah.
[woman laughs]
Bonus, tug.
[Hutchinson] Bonus needs some confidence building,
some encouragement.
Oh! Try again.
But he is interactive.
Light. Yes!
He is really good at precision when it comes to tasks.
Come on, get up. Yeah!
[narrator] Three keys to training a dog…
Up.
[narrator] Patience.
Yeah! Good boy!
-[narrator] Repetition. -Wow.
Light. You got it.
Yes! Good boy.
[narrator] And understanding what they're trying to say.
So our job is to teach people what your dog is saying to you,
what your dog is thinking.
Good boy. Good.
Dogs are constantly communicating with us.
All you have to do is watch your dog, listen to your dog.
He's giving you all the information you need.
-[woman 1] Oh my God. -[woman 2] Hi!
[laughter]
[woman 2] Hi!
[dog whimpering]
[man] When I'm looking at the body language, the tail wag is gonna say a lot.
A loose tail tends to indicate less stress,
more happiness, more curiosity.
[dog whimpers]
A tighter tail, if we think about it in human terms…
This is an exercise for everybody at home watching.
Tighten your butt right now, and then ask yourself how you feel.
And there's usually an emotional correlation there.
The tail tucked or wagging low indicates to me that there's some stress.
[barks]
The helicopter tail usually comes with a good, big butt wiggle.
Typically, when we see that, there is an emotional experience
that seems to be really positive for the dog.
From the current science,
if a dog is seeing somebody that they know and has a positive association with,
we see a tail wag to the right.
It's pretty cool.
But I want to see what's happening with the body
that might be correlating with what's happening with the tail.
[barks]
Dogs have 16 different facial expressions.
[camera clicks]
-[dog growls] -[Draper] Anger.
-[dog whimpers] -[Draper] Anxiety.
-[dog whines] -[Draper] Pain.
-[dog barks] -[Draper] Happiness.
-[dog whimpers] -[Draper] Sadness.
You compare that to humans, who have about 27 different facial expressions.
And then chimpanzees, one of the smartest mammals in the world,
have only 13 to 14 facial expressions.
So dogs learned a lot of that from us by what we do and what we've shown them.
[Hutchinson laughs]
Oh, your face. Can you do a downsy?
Good boy. Fastest I've ever seen him do this for a treat.
So this sweet little guy is Peabody.
He has a relaxing presence.
When Peabody's around, everybody's chill.
Most of the time, he likes to lay in the sun.
When all the dogs are running loops around and playing tug,
he can be found sunbathing.
P, get.
Training can be a little slow.
You got it.
He does need work on retrieving.
However, he performs interactive skills very well.
Visit.
Interrupting anxiety, that's actually a task.
That's a trained behavior.
Good boy.
So we are constantly evaluating their appropriateness
to become service dogs.
[narrator] Most dogs sleep about half of every day.
[barks]
[narrator] But not all.
[Hutchinson] So this silly boy is Nemo.
Nemo is very animated.
You got the pterodactyl.
-[barks] -No.
Nemo, down.
No.
Yes. Good boy.
-No. I don't think we were doing that. -[barks]
Not that one either.
Nemo is very much in love with life.
He does need to focus when it comes to working.
One more. Fetch.
Nemo!
[narrator] Twenty percent of dogs show ADHD-like behavior,
twice as many as humans.
Whether Nemo is one of them is yet to be seen.
Dogs with ADHD can be more impulsive,
even hyperactive.
But that doesn't make them untrainable.
[woman] Nemo, tug.
[Hutchinson] Nemo has a job to do in the real world.
[woman] Yeah. That's it. Good boy.
Drop.
Yes. Juice.
That's it. Yes, sir. Good boy. Very nice.
Nemo, he's really excelled in that retrieving-items command,
as well as learning that tug command.
Hey.
He's animated and loving, and he enjoys training,
but we still have to see if we feel that he can do his job reliably.
I always have to say "if" because nothing is guaranteed.
We have seen him alert bark at times.
[barks]
That is something you can get kicked out of restaurants, stores,
so that would disqualify him from becoming a service dog.
[narrator] If Nemo can't control his barking,
he will not graduate and be matched with someone in need.
Barking meant something different before the human-canine bond evolved.
[wolves howl]
[Hecht] So wolves howl as a group.
It's an important form of social communication for them.
But they don't bark in the way that dogs do towards humans.
[barking]
Dogs seem to bark in a more emotional way, potentially to recruit human attention.
[whines, howls]
Some breeds of dogs howl a lot.
If you have a Siberian Husky, you're probably, like, nodding right now.
[vocalizing]
[man] Good girl.
[vocalizing]
[man] I love you.
[vocalizing]
[dogs howling]
[narrator] Humans are so vocal…
[woman] Guys!
[narrator] …we've helped dogs to find their voice.
[screeching]
Just like with people, different people are gonna talk to me in different ways.
[howling]
-[howling] -A bark is not just a bark.
Some dogs are barkers.
But the change in the tone can make a difference.
[whining]
Higher stress situations are going to lead to a higher pitched,
almost distressed kind of bark.
[continuous high-pitched barking]
Repetition at a high pitch without pausing,
it's generally a state of distress.
[high-pitched barks]
If the dog is barking and pausing,
then it would indicate there's still some cognitive ability.
[woman] Walter.
[yowling]
-[woman] No. -[Beisner] There is no bad dog.
There is behavior that we don't understand,
but the dog's behavior is 100% appropriate based on its experience in that moment.
[barking]
[narrator] Barking and hyperactivity
are two behaviors that Penn Vet can actually use to help save lives.
Good girl, Lucky!
The Penn Vet Working Dog Center originated after the disasters of 9/11.
We realized that there was no science to really support these amazing dogs
that were doing the search-and-rescue work.
We needed a program that we could research the dogs,
we could understand the dogs,
and improve the health, the well-being, the welfare of these dogs,
and the availability because there weren't enough of these search-and-rescue dogs
to do the jobs that we're asking for them.
Here at the Working Dog Center,
we're looking for very, very different types of dogs.
We know, in any litter, the dogs that won't sit still
really want to work in detection-type, active jobs.
Anything that dogs do with their noses.
Search and rescue.
[barking]
Nice job!
[Otto] Explosive detection.
Drug detection.
[sniffing]
[Otto] Medical detection.
[sniffing]
[Otto] And so they have to have the physical strength,
and they have to have what we call body awareness.
These dogs are climbing ladders, they're navigating unstable surfaces.
They have to have that strength, that awareness.
They're almost like gymnasts.
By having the Canimetrics program, our dogs are physically fit…
[woman] Good job, girly.
[Otto] …which allows them to work in a safer manner.
We do warm-ups before they do activities.
Good.
[Otto] We actually have dogs doing planks, which is core-strength training,
and it's amazing what that does for their abdominal muscles,
their back muscles.
Most dogs in the United States are actually overweight,
and that shortens their life up to two years
when we're talking about 10 to 20% overweight.
So it's really important for us to keep these dogs strong and healthy.
[woman] Good girl. Nice job.
[narrator] In the wild, wolves don't need calisthenics.
Being fit is the difference between life and death.
Dogs are both prey and predator.
[dramatic music playing]
So they were trying to escape, or they had to use that ability to run
in order to chase down food to survive.
[barking]
[Lee] If you look at a greyhound, compared to other breeds,
they can have 12% more muscle in their hind limbs than the average dog.
[Draper] A greyhound runs up to 45 miles an hour.
Pretty impressive.
The average speed of dogs is about 15 to 20 miles per hour.
Then you have the Basset Hound,
who has the mind-blowing speed of five miles per hour.
["Ride of the Valkyries" by Wagner playing]
[music warps]
[narrator] They might not all be the fastest,
but dogs are nature's elite high-endurance athletes.
[Lee] Some of these sled dogs that race, they run 100 miles a day,
and they're only 40 to 50 pounds.
So they have a greater lung capacity, a faster metabolism,
and a more efficient cardiovascular system.
[narrator] At rest, a dog's metabolism is about the same as a human's.
But when they need it, dogs can shift gear,
recording the highest sustained metabolic rate of any animal.
It means they use the same amount of calories
three times more efficiently than a Tour de France rider.
And when they're done, they downshift back to rest.
All of our dogs are still wild at heart.
It's not so much the plastic Frisbee.
It's the predatorial drive to chase something.
[Draper] They don't have collar bones,
which allows them to be more flexible and change directions really quickly.
They have tails that help balance them,
and they have a very long, flexible spine.
[Lee] As much as we try to get in the mind of a dog,
of, like, the pathophysiology of how a dog does it,
it's really split-second decisions where a dog is chasing whatever it is.
It may be prey, it may be a plastic disc,
but in their mind, within seconds or milliseconds,
their brain is undergoing computation
where they're figuring out how far it's gonna go,
what direction, what direction to pivot,
and the ability to turn around
and catch it in their mouth at the same time.
But not all dogs are created equal when it comes to catching Frisbees.
[narrator] Dogs all have their strengths and weaknesses.
It's up to us to nurture them as individuals.
[Draper] Depending on the breed, dogs need different types of enrichment
to give them a fulfilled life.
-And stimulate their mind. -Right.
[narrator] It pays to let your dog be themselves.
Oh, yeah.
Our dogs work because they show a desire to work.
Ready? Okay. Release.
[narrator] Peabody, Bonus, and Nemo
have all completed the first stage of the program.
Speak. Speak.
-Yeah. Yeah. Speak. Yeah. -[barking]
So we have basic commands,
the sits and the downs and, you know, all of that.
Impressive. Okay. But can a dog sit when there's a roller coaster behind them?
[people screaming]
[narrator] It's time for them to take what they've learned outside the classroom.
[Hutchinson] Field trips give us a lot of information
about who each dog is.
Good job, buddy.
We are looking for how the dog thinks, feels, and operates.
[girl] Hi, doggy.
[Hutchinson] We're at Adventureland with Mr. Peabody here.
It is full of noise…
[people screaming]
[Hutchinson]…distractions.
We want to see if he is able to pay attention to me in this environment.
Ready. Can you jump?
Yay. Good boy. Nice.
[Lee] When it comes to hearing, because they hear higher frequencies,
dogs hear four times more than humans do.
[people screaming]
[high-pitched ringing]
[Lee] We're not always cognizant of that as dog owners.
-[high-pitched ringing] -[people screaming and laughing]
[Draper] They actually have 18 muscles in their ears that are used for hearing.
-[people screaming] -[heavy bass beat playing]
[carousel music playing]
[Draper] You may feel like it's a quiet day,
but he's hearing this loud sound from over here,
-this weird sound from over here… -[people scream]
[bell ringing]
…which is startling, particularly if he doesn't know where it's coming from,
so you have to take that in consideration
when you're trying to train and socialize them.
[Hutchinson] Peabody, down. Down.
Yes. Good boy.
Peabody is a very, very stable boy.
[Hutchinson laughs]
I don't think he's bothered.
We like to call 'em "bombproof" dogs.
I'm sure a bomb could probably go off 15 feet away from him.
If he looked back… That's a big if, uh… [laughs]
…he would be unfazed.
[snores]
[Hutchinson] That is a very strong quality,
especially when we find the person
that could really benefit from a dog like this.
[narrator] The more they learn about how the dogs behave,
the better match they can make when it's time to pair them with a human.
[people screaming]
Bonus, I wouldn't put him next to a rollercoaster necessarily.
Bonus, let's go.
He's slightly more noise sensitive.
We are taking Bonus to a restaurant. There's gonna be a lot of people.
They're probably going to pay a lot of attention
to the fact that, "Oh my goodness, there's a dog here."
Not to mention, he's super handsome.
Oh.
Come on, buddy.
He has to ignore the distractions
when he's out in the real world with his person.
There's going to be trays passing along, food on the floor.
What I'm looking for is
is he gonna be restless while we're dining and having a meal and he's not?
All right, buddy. Sit.
Good job, buddy. Good job, buddy.
Bonus, under.
We consider dogs to be an extension of a person.
Yay. A little bit more.
Which is why positioning for different things is super important.
If he's neatly tucked away under a table, or he's under a chair,
he's going to be safe.
He's not gonna get stepped on.
[narrator] Once in position, Bonus is at ease.
-[sniffing] -Until the steak comes out.
[tense music playing]
[Hutchinson] We don't want our dogs going after food that's on the ground.
They might think a pill is food. It may be toxic.
Nope, nope, nope.
Good.
It takes a lot of self-control for a dog
not to eat a piece of steak in front of 'em.
These guys want it. There's no denying that.
Yes, good job. Hi, buddy.
Eye contact is super important.
He's turning away a little bit.
Yes. Good boy.
[sniffs]
We use it as a tool of reinforcement.
Good boy. Nice job.
A dog that checks in can get positive feedback from the handler.
"Hey, you're doing the right thing."
Good.
Good boy. Yes.
[narrator] When humans aren't involved,
dogs use eye contact in a very different way.
[sheep bleating]
Border Collies use "the eye" to control sheep.
The hard stare mimics hunting,
so the sheep flock together
and move to the dog's will.
Wolves do the same,
but they finish the job.
[wolf growls]
Canine vision evolved to find and track prey.
Rods help see in poorly lit, dark areas.
Dogs have more rods. Because of that, they have better night vision than we do.
And dogs also have a reflective layer on the back of their eyes
called the tapetum lucidum.
Light will reflect on it and act as a flashlight in poorly-lit situations.
Cones are what allow us to see colors,
and humans have three different types of cones.
Dogs only have two, so dogs don't see certain colors that we do.
They just only see in hues of yellow, blue, grayish-brown.
They're much better at things that are actually moving.
We think that the world's a little blurrier than what our world is.
They definitely rely on vision,
but they can live without it.
Dogs are built to smell the world.
I like to use the phrase that dogs smell in color
because it kinda gives us something that we can relate to
because we use vision as our primary sense.
[Hutchinson] Nemo. Let's go, buddy. We got this.
[narrator] Dogs also smell in three dimensions.
They can make a spatial map of a room using just their nose.
[sniffing]
[Hutchinson] Supermarkets are very tempting, challenging places
where food is often at dog level.
There's meat, and there's fish, and there's produce,
and there's all kinds of things, but forget about all of that.
[narrator] A dog's nose can detect millions of different smells.
It even knows if their owner was here… yesterday.
[sniffing]
The challenge for Nemo, keep his focus on the trainer,
not the food.
[Hutchinson] Oops. Nemo. Yeah.
You'll get your food later, kiddo. Let's go.
It's a little bit of a challenge with Nemo,
especially in aisles of smelly, wonderful things
that any dog would love to sink their teeth into.
It's very easy for Nemo to veer off and want to sniff.
No fish. Come on, buddy.
So what I'm looking for is that Nemo keeps his attention on me,
because in the real world, his person is going to need him
regardless of what is going on.
[narrator] While not every dog is welcome in a supermarket,
every dog can benefit from learning to control their impulses.
[man] Yo, that dog's totally gonna steal that guy's pizza.
[women laughing]
The anatomy of a dog's nose
is designed to allow the dog to experience the world through odor.
[sniffs]
The nostrils themselves are designed so that about 10 to 15% of this air
goes directly to what we call the olfactory epithelium,
the part of the nose that receives information about odor.
It's a labyrinth.
There are just huge amounts of nooks and crannies
where all of these little cells that capture odor are sitting.
The dog has more types of these cells than humans do,
a higher density of these cells, and a higher absolute number.
That information is processed in their cortex.
When they exhale, it goes out to the sides through the little slits,
and that's a really important component
'cause they can breathe and smell all at the same time.
[sniffs, grunts]
[woman] Search.
[narrator] This remarkable nose can also be used to save a life.
[sniffing]
[clicks clicker] Yay-hay-hay-hay!
So we have several tools that we use when we're training a dog.
We have the scent wall.
So these are just ports.
On the back side, we can insert the source of the odor,
and the dog will have to learn to very systematically search that wall
to identify where the odor is.
That translates to how they will search
to identify contraband or hazard that might be out there.
From a training perspective, we put out what we call "distractors"
to see will it interfere with their focus
so that it actually diminishes their ability to use their nose
because they're distracted?
[woman clicks clicker] Good boy! Wa-ha-haw!
[Otto] When we think about our dogs,
we really think of them as being extraordinary.
And the thing that stops my heart every time I see it
is when a dog goes out into the rubble pile…
and can see that there's masses of people
working and standing and on that rubble pile.
And they go, "Okay, you, you, you, you're all fine,
but I smell somebody else."
And they can't see them.
[barking]
[Otto] How they can find a concealed person,
someone who would, in a real disaster situation, be trapped…
-[barking] -[Otto] …is just mind-blowing.
[barking]
[woman] Yes! Woo-hoo-hoo!
We don't have any equipment that can match the dog's ability,
their speed, and their accuracy in finding these concealed people
whose lives really depend on being found quickly.
[barking]
And that is a superpower.
[reporter] When the 7.8 magnitude earthquake
rocked Turkey and Syria,
Colin the Collie, a member of the UK's International Search and Rescue Team,
spent ten days in one of Turkey's hardest-hit areas.
Dogs are responsible for 11 successful rescues.
[Otto] Dogs have been used for scent work for centuries,
but it's only been more recently that dogs have been used
to help us identify odors associated with disease.
Cancer is probably the one disease that has received the most attention.
All right, Amritha, what do we have Osa doing today?
So Osa is going to find our cancer-detection training odor
on our eight-port scent-detection wheel,
the same wheel we use for our Covid-detection studies.
-[woman] Ready, Osa? -[yips]
[woman] Search!
[Otto] With cancer detection, we take a blood sample from a person with cancer.
We ask the dog first to sniff that sample.
-And then we click a little clicker… -[clicker clicks]
-Good girl! -[Otto] …and they get a treat.
-Nice job, Oss! -[Otto] We do that a couple of times.
Then, all of a sudden, there's another sample,
and here's that healthy patient.
When they put their nose on the sample that is not from the patient with cancer,
they don't get their reward.
[woman] Ready, Osa? Search.
[Otto] The dogs are constantly processing the information, they're adapting,
and they're able to parse out the relevant odors
and recognize that this is the cancer.
-[clicker clicks] -[woman] Good girl!
Yes. Good job, Osa.
Even if people have a different diet, come from different ethnic backgrounds,
if they're from a different geography,
a lot of times, the machines get confused by that.
-[sniffing] -[clicker clicks]
-[woman 1] Good girl. -[woman 2] Good job.
So there's something very amazing about the dog's brain
and their processing ability.
[panting]
So what happens if there's no target odor in the wheels?
So if the wheel doesn't contain any target substance,
what they do is they will jump on this platform right here,
and they'll sit,
and that tells us that they have sniffed all of the samples on the wheel,
and they don't believe any of them to be the target sample.
-So like an all-clear signal. -Mm-hmm.
[sniffing]
[Amritha] Diseases like cancer have really low incidence rates,
so we want to make sure
that the dogs are willing to pass a lot of negative samples.
-[clicker clicks] -[woman] Good girl.
[laughter]
[woman] Good job.
[laughter continues]
[narrator] Dogs can smell cancer, diabetes, even Parkinson's.
They can smell our mood.
Adrenaline.
They can even smell our stress.
Being able to pick up on such minute changes is a superpower.
She came up and put her nose on my belly,
and I knew in my gut that something was wrong.
Sierra was telling me I had ovarian cancer.
I believe she saved my life.
[Hecht] We all experience attachment bonds with the dogs in our households.
Dogs are bonded to us. We're bonded to them.
At Harvard University, we're looking at the formation of attachment bonds
between dogs and children.
[narrator] Turns out our bond is more than just skin deep.
Cortisol is a hormone that bodies release during stressful experiences.
When people have an attachment bond with a dog,
the presence of that bonded partner can buffer that bump in cortisol
that occurs during a stressful event.
Interactions between dogs and humans
also cause release of a hormone called oxytocin in both species.
This is a hormone that is involved in the formation of social bonds
and the feeling of positive interactions with an attachment partner.
[narrator] Dogs create attachment bonds with us
as if they themselves are humans.
At Canine Companions,
this attachment bond is the key to making a successful match.
[woman] Dress.
[narrator] The dogs have mastered the basics in the classroom
and taken what they've learned into the real world.
Now the trainers have decided that seven of the 11 dogs in the current class
have passed stage two.
They're ready to move on to the final and most important stage,
building a bond with someone in need.
[woman] All right, guys, welcome to pre-matches.
All of the trainers have met together, talked about the dogs, their puppyhood,
everything that you guys have given us,
and we have made our best guesses
of what dog will be best pre-matched with you guys.
[narrator] Seven potential recipients from all over the Northeast
have been invited to Canine Companions to meet these seven dogs.
All the trainers have been together…
[narrator] If the dog and the person can form an attachment bond,
they will go home together.
It can take time for a dog to adjust to a new owner,
but kindness and consistency help ease the transition.
This is the beginning of your relationship,
so please remember to keep your expectations and consistency
as you continue to work with your dog.
No googly eyes at the dogs next to you.
Please give everything, all of your all, to the dog that's in front of you.
We want the relationship to start now.
All right, are we ready?
-[man] Yeah. -[girl] Yes.
[woman] Awesome.
James, you have been pre-matched with black Lab-golden cross, Biro.
-[man] All right. -[cheering and applause]
[woman laughs]
[woman] You can hold that leash.
[gentle, emotive music playing]
[woman] Christy, you have been matched with Goldie the Fifth.
[applause]
-[laughter] -[woman] Aww.
[girl] Doggy kisses.
[woman] And Jaz, we didn't forget about you!
You've been matched with yellow Lab-golden cross, Bonus.
[man] Bonus.
-[cheering and applause] -[woman laughs]
Thank you. Sure.
Hi, Bonus!
[laughing]
[woman] Congratulations, everybody.
You can take a few minutes. Go ahead and love on those dogs.
[man] Who is that?
Can you say "Bonus"?
Bonus.
-[Sandy] You can say Bonus. -[man] All right.
Good job.
And action!
Yeah boy!
Mother and dad.
This is my mom and dad.
-Tell us a little bit about Jazzy. -B… uh, b…
'Cause she's kind of a knucklehead sometimes.
Oh, I…
You're mean.
-[laughs] -My dad.
[Jazmin's dad] So Jaz, actually, when she was born,
we had complications from day one.
And she spent a lot of time in the NICU.
-She has trouble with talking. -Hi.
She can say, "Hi."
She comprehends everything.
Humor, sarcasm, she gets it all,
but her ability to communicate to you is a challenge.
She needs a dog. She has to have a dog.
It is one of those imperatives for her life.
[indistinct chattering]
[girl laughing]
[narrator] The dogs that didn't get picked…
will still have a chance to change lives.
[Hutchinson] We have decided, unanimously,
that Mr. Peabody will do very, very well
with a veteran who has PTSD.
A steady, calming presence is the type of work he enjoys,
is the type of work that he has excelled at.
Let's go.
And that's the best fit for him.
[laughs]
[narrator] As for Nemo, he's cut out for something different.
Nemo, no.
We definitely don't call it failing because these dogs are amazing.
But Nemo, he didn't make it through our program.
-[barks] -No.
So we give him the opportunity to live a different life.
He's gonna make one heck of a pet dog.
The puppy raiser, the family that put all their time and love into them
for the first year and a half of their lives,
they have the opportunity to adopt the dog back.
[bright music playing]
-Hey, Nemo! -Nemo!
How ya doing, puppy? Huh?
[narrator] Adopting a sweet boy like Nemo is a no-brainer.
[man exclaims]
How have you guys been?
[female owner] I know. It's so exciting. It's so exciting.
[woman] We are actually gonna go right into our first practice of the day,
and we're gonna start to work with these dogs and build the bond. Okay?
[narrator] For the dogs that are matched, it's two intensive weeks.
Mark with that "yes" when he looks at Jaz.
-Bonus. -Yes.
[Jazmin] Here.
[narrator] In order for Bonus to go home with Jazmin,
they need to build a bond by graduation.
Look him in the eye there.
-Bonus. -Yes.
[narrator] The best way to nurture any new relationship,
stay positive and learn to communicate.
When you want a dog to be consistent, reliable, be your partner…
We literally make partnerships.
Good boy. Good boy.
Really nice.
[Hutchinson] Communication is extraordinarily important.
He might not know he's communicating to you,
but he's always communicating to you.
For us to communicate to the dog, we've gotta learn how to talk dog,
and that's how this whole program works.
[narrator] Now researchers are studying to see
if dogs can actually learn to talk human.
[automated voice] Play.
[woman] Okay, we'll play.
When you communicate with somebody of another species, it's mind blowing.
Imagine if you had to communicate to a turtle.
Like, I wouldn't even start imagining what it means to communicate with them.
[automated voice] Scritches.
[woman] You want some scritches?
Yeah, there you go. There's some scritches.
[Rossano] I'm trying to train pets to learn symbols, words,
as a window into their minds,
so that we can learn something about what they're thinking, experiencing,
and able to communicate about their emotions too.
Hey.
[dog whimpers]
[robotic voice]
The devices that we use for this study are an adaptation of devices
that are being used with nonverbal humans for a long time,
and we call it augmented interspecies communication devices.
-[automated voice] Pea… Pea… Peanut. -[woman] Mm-hmm.
-[automated voice] Peanut. Peanut. -[yips]
[Rossano] There's been research, for example, with primates
with a similar device called a lexigram,
where you have symbols that when you push, they'll produce a sound or a word
that humans can understand.
But usually, the studies are conducted with one or two individuals.
We have 10,000 dogs from 47 countries.
The ones who have the most buttons are around 150.
They've been in the study a couple of years.
-[automated voice] Snuffle mat. -[woman] You want your snuffle mat? Okay.
[woman] Parker's two and a half years old,
and she has been using the buttons to communicate
for almost two years, since she was six months old.
These are the buttons that Parker uses.
So each of them have, like, a little design.
And when you press it, the audio comes from the base there
that it's Bluetooth linked to.
[automated voice] Outside.
Parker both will ask me questions and respond to questions
that I ask her either verbally or using the buttons.
[automated voice] What Parker want? Hmm?
Stick.
[woman] Yeah! Okay, more stick.
The way that she uses it as a means to communicate with me in a deeper way
really accentuates our relationship overall.
[automated voice]
[woman]
I think you can get caught up in, like, "Oh, dog people are crazy."
"They just think dogs are little people."
But, yeah, just imagine being a scientist for a minute.
[automated voice]
[Hare] And you're trying to understand how non-human animals think.
And so the question is now becoming,
"Well, how sophisticated is their communication gonna become
now that they've got this new way to talk to their human family members?"
So I don't know! We're gonna see what's possible here.
It's gonna be fun.
[siren wails]
[automated voice]
[Rossano] Trying to combine three, four buttons,
they can produce a sentence to communicate novel concepts.
That's the thing that fascinates me the most.
[automated voice]
[woman 1] He says, "Shut up. I want to take a nap."
[laughter]
[woman 2] Fashion is my first dog.
We've been doing this for three years now.
As far as the buttons are concerned,
I definitely think that they have helped build our relationship.
I really think that there's a level of validation
in my understanding of what I already think he wants,
and just that communication because of these words.
I have a one-year-old as well.
And for a long time, was just crying whenever he wasn't happy.
But now he can tell me "water" and "cracker"
and "Mama" and "Dada," and so can call for help.
Those five, six words already have changed my life.
Imagine having 200 words.
That's the thing that excites me.
It's like, if we can get a little window into a dog's mind,
that would be fantastic.
[narrator] The average dog can learn 165 words.
[dog whimpers]
The smartest dog on record, Chaser, knew more than a thousand words.
I think that the types of intelligence that different dogs have can really vary,
just like different people have different types of intelligence.
[woman] Sailor, what happened? Sailor, what happened?
Sailor.
Sailor, what happened?
I don't know if I'd call any dogs dumb. That doesn't seem quite fair. [laughs]
[narrator] Smart or not, all dogs do some unusual things.
Puppies often chase their tail because they don't know it's a part of them.
Some experts believe that dogs like to poop facing north.
Scientists believe dogs do dream…
-[dog barks] -[narrator] …often about their owner.
[woman] Daisy, are you dreaming?
[laughter]
[narrator] Researchers at Harvard are working to decode
why dogs do the things they do.
[Hecht] We're trying to find out what's going on inside dogs' minds
through a combination of behavior testing and also MRI scans.
[gentle music playing]
[machine beeping]
[Hecht] So this is the hypothalamus.
The hypothalamus is a brain region
that is involved in, um, what we think of as the four Fs.
Feeding,
fighting,
fleeing,
and reproduction.
And it's crucially involved in the flight-or-fight response.
[narrator] This brain region also helps determine personality,
why some dogs are fearless and others timid.
[Hecht] Along with MRI studies, our life-experiences study
is looking at the effects of early-life stress in dogs.
Our preliminary results indicate early-life stress
does influence fear and aggression behavior later in life in dogs.
Dogs definitely experience anxiety.
[dog whines]
[narrator] As many as 70% of dogs suffer some form of anxiety.
It can come from early life experience.
And sometimes you're just born with it.
[Hecht] A state of stress or worry or fear is a very primal, ancestral emotion.
I think anybody that has a dog probably has experienced their dog feeling anxious,
and it's easy to interpret and empathize.
[narrator] One of the most common canine anxieties happens when we leave.
-If you could ask her to stay in here. -Townsend, sit.
[Hecht] We do a behavior test where the owner leaves the room,
so the dog is left alone.
If the dog experiences separation anxiety,
it's probably going to come out in that situation.
And so we watch the dog carefully,
and if it seems like they're starting to show signs of distress,
we have the owner go back.
Some dogs are completely mellow.
They might sniff around or maybe curl up and take a nap.
And, um, other dogs really are, you know, barking or howling
or scratching at the door.
I think this kind of gives us a window into what dogs are doing
when we're not there.
[narrator] Anxiety can cause aggression, depression,
even destructive behavior.
[growling]
[panting]
[narrator] Luckily, some of the same things
that relieve stress in humans
can also work for dogs.
["Flower Duet" by Delibes playing]
[Hecht] There was one study that looked at dogs' affective responses
to classical music and other types of music.
Preliminary data suggested classical music might have a calming effect on dogs
and rock music might have the opposite effect.
I think this is an area where more research could be helpful.
[narrator] Often, nothing relieves your dog's anxiety more
than you coming home.
[barks]
The more time you spend together,
the stronger the attachment grows.
[barking]
[woman] All right, so I'm gonna start heading in.
I'm gonna stop, say "Okay."
As you go by, you're gonna do this, you're gonna that.
[narrator] Jazmin and her family have spent the past two weeks with Bonus.
It's time for them to take the final test and prove they've built a bond.
Bonus, let's go.
One of the challenging final exam tests
is to walk the dog through an obstacle course
with no leash, no nothing, just talking to the animal.
Bonus, get.
Get. Come on.
There it is. Yes.
Bonus, let's go.
Bonus, jump.
Yes.
-[woman] Good job. -Give.
-Good job. -[woman] Very good.
Jaz, praise your dog if he's doing good.
-Yeah! -Good boy.
[woman] Booty scratches!
-Very nice. -You ready?
Bonus. [kisses] Tug.
Come on. Come on.
This. Tug.
Come on.
Whoops. Tug.
[woman] Yeah, there you go, Jaz.
-Yeah. Tug. -[Jazmin's dad] Tug.
[woman] Yay! We'll take it.
Bonus, push.
-Good boy! Good boy! -[cheering and applause]
Jaz, take a bow. [chuckles]
[Sandy] He was phenomenal.
He absolutely knows his job, and he absolutely knows us
because he stuck with you guys the whole time.
Yeah.
-Just give him a little kissy. -[Jazmin] Mmmm!
[laughter]
[narrator] It's official. Bonus has passed.
But before he's done, there's one last symbolic moment.
[Hutchinson] Before graduation, the dogs see the puppy raiser
who loved them for a year and a half of their lives
so they can get some quality time.
Hi, Bonus!
-Hi, baby! -[woman 1] Who's that?
Oh, yes.
Oh, my buddy. I missed you.
[Hutchinson] They're still dogs at the end of the day.
They have a past. They have history.
[woman 2] Come here, Berkley!
Hey! Berkley, it's me!
[Hare] The stories of the soldier coming home after years.
[woman 3] Zeke, go look who's here.
[Hare] You know, we all wanna know…
[dog barks]
…does the dog remember?
[barking]
[woman 2] Hey, Berkley, it's me.
Usually, it takes them a second or two to, "Is this right? Is this…?"
[barks]
It's me. It's…
[Hare] And best evidence is…
Look, it's me.
[Hare] …they do.
Yeah!
[laughs]
Then they go berserk.
[woman 2] Hi!
[man 1] Now he knows ya. Now he knows ya.
Hi, Ruthie!
[man 2] Hey! Come here.
[woman 4 laughing]
[woman 5 squeals]
[Hare] Dogs certainly can remember what different dogs
that they've encountered early in their life smell like for years,
and people too.
[speaking indistinctly]
[narrator] Our bond is unlike any interspecies relationship on Earth.
Yay.
[narrator] But do they actually love us?
Yeah, I think dogs love us. Um…
I think that dogs' experience of love
might be different than the human experience of love.
[baby cries]
[Hecht] Dogs show some form of emotional contagion.
They can respond appropriately
to the emotions of other individuals in their social group.
[Woods] They're family. They absolutely love you.
[girl sobs]
[Woods] That's why they're doing that weird eye thing
when they're just kind of staring at you.
They're just hugging you with their eyes.
That interspecies connectedness is, like, quite amazing.
So, absolutely, they love us.
[Hutchinson] I think that with the right relationship,
if a dog feels safe, confident around its human,
if a dog becomes happy when they see their human,
if a dog enjoys petting from their human,
eh, I can call that love.
That's how I love people.
I'll call that love.
On behalf of Team Bonus, my wife, and the entire graduating class,
we truly wanna say thank you to everyone.
You know, nine years ago, we were here with Jazmin,
and she could barely talk.
She never engaged with anybody.
And that was when we met our first dog.
And it has made all the difference in the world.
Every day I see her strength and patience
and her incredible spirit…
…and her incredible spirit that lifts up everyone she meets.
It's why you puppy raisers do it.
It's what is so special about this entire program.
[cheering and applause]
These dogs change families in unimaginable ways.
[applause]
[Jazmin's dad] Good boy. Bonus, sit.
[automated voice] I love Bonus.
Nice.
So when you realize how amazing dogs are and all that they do for us…
Here, boy.
[Hare] …the question then becomes, "Well, what could we do to be better?"
What we can learn about dogs is it's better to be friendly.
[woman] Hi! You're so cute.
[Woods] It means survival of the friendliest
is a very powerful strategy.
[woman] Yeah!
[Woods] Dogs will accept you no matter who you are or where you come from,
and they have bridged an entire species divide.
♪ Oh, the happy dog ♪
[Woods] And they can live with us in perfect harmony.
Dogs are such a great example of what true acceptance looks like.
That is gospel truth. You don't need science to know that.
[upbeat music playing]
Buddy.
[girls screaming and exclaiming]
[Draper] I just wanna be a French bulldog. I wanna lay around and eat,
and go out and poo, then come back and lay down in the sun
and have somebody pet me for about five minutes and then leave me alone.
If I'm a French bulldog, I'll figure it out.
