Hey everyone! Let me tell you about an incredible dog named Chaser. Chaser is a border collie who knows over 1,000 words, which is similar to the vocabulary of a 4-year-old child. What’s even more amazing is that Chaser can tell the difference between nouns and verbs!
Chaser’s owner can give commands like “Take lips” or “Paw lamb,” and Chaser understands exactly what to do. This shows how special the bond between humans and dogs can be. Even though not all dogs are as skilled as Chaser, like Oliver, who struggles to find his bone, the fact that we try to communicate with our pets and they respond is truly remarkable.
Have you ever wondered if dogs understand the words we say or just the way we say them? A study from the University of Sussex found that dogs can separate the meaning of words from the emotion in our voices. When dogs hear commands without emotion, they turn their heads to the right, indicating they process the words in the left side of their brain. When they hear emotional sounds, they turn to the left, suggesting they process emotions on the right side.
Sometimes, dogs might seem to understand us better than they actually do. This is similar to Clever Hans, a horse from the early 1900s, who appeared to solve math problems but was actually responding to subtle cues from his handlers. This shows that communication is not just about words but also about body language and emotions.
Charles Darwin once suggested that the way we express and understand emotions might have evolved from animals. Today, scientists are still exploring this idea, but research shows that dogs share some emotional intuition with us. Unlike their wolf ancestors, dogs seek eye contact with humans, which helps them understand us better.
When we try to read emotions in others, we often look at the right side of their face. Dogs do this too, but only with human faces, not with other dogs. This suggests they genuinely want to understand us. In Hungary, researchers found that many people can interpret the meaning of different dog barks, showing that we can “speak dog” to some extent.
The connection between humans and dogs makes sense when you think about it. We’ve evolved alongside these animals for thousands of years, turning wolves into our loyal companions. Even if we don’t always understand each other perfectly, dogs are always there to listen, making them true best friends.

Imagine you are training a dog like Chaser. Create a list of 10 simple nouns and verbs. Pair up with a classmate and take turns giving each other commands using these words. See if your partner can understand and act out the commands correctly, just like Chaser would!
Conduct an experiment to see how dogs react to different tones of voice. Record yourself giving a command in a neutral tone and then with an emotional tone. Play these recordings to a dog and observe their reactions. Discuss with your classmates how the dog’s response changes with the tone of voice.
Watch a video of a dog interacting with humans. Pay close attention to the dog’s body language and how it responds to human cues. Write down your observations and share them with the class. Discuss how body language plays a role in communication between dogs and humans.
Look at pictures of human faces showing different emotions. Try to identify the emotion by focusing on the right side of the face, as dogs do. Discuss with your classmates how easy or difficult it was to read the emotions and how this might relate to how dogs perceive human emotions.
Listen to recordings of different dog barks and try to guess what each bark might mean. Are they happy, scared, or alerting someone? Share your interpretations with the class and see if there are common patterns in how you understand the barks.
Here’s a sanitized version of the transcript:

Hey everyone! I just learned about a dog named Chaser. Chaser is a border collie who has a vocabulary of more than 1,000 words, which is similar to that of a 4-year-old child. What makes Chaser even more special is that he can separate nouns from verbs.
“Take lips. Do it, girl!”
“Good girl, good girl.”
“Paw lamb, paw lamb, Chaser.”
“Good girl, good girl.”
“Nose ABC, nose ABC.”
“Good girl, good girl!”
This is Oliver. Oliver, do you think you’re smarter than Chaser? What do you say? Yeah, let’s go find out. Come on! Get your ball. Where’s your ball? Get your bone. Where’s your bone? Nope, that’s your ball. Where’s your bone? Bone. Bone. Nope. Find your bone? Where’s your bone?
Okay, so maybe Oliver’s not that good at this particular test, but the fact that we even try to communicate with dogs, and that they communicate back with us, means that the human-dog relationship is truly something special.
“Who’s the best boy?” (baby talk)
“I… have been known to talk to dogs a little.” (baby talk)
“(baby talk) Or a lot.” (baby talk)
It’s hard to know if they’re responding to the words, or just the emotion in my voice, or the fact that I sound silly. One recent study suggests it’s both. Researchers at the University of Sussex played sounds out of speakers on both sides of a dog. When dogs heard commands stripped of their emotional context, they turned their head to the right, suggesting they process verbal meaning in their left hemisphere. When they heard emotional sounds in the voice, but the words were jumbled, they turned to the left, suggesting they process emotional sounds on the right.
These experiments show that dogs can definitely separate the meaning of words from the emotion attached. But how much information do they take from each? When I ask my dogs, “Do you want to go for a walk?” they aren’t processing the real meaning of that sentence the way we do. They probably don’t think about it the same way we do.
As good as dogs are with words, in many of our interactions, there’s probably a good amount of Clever Hans at play. In the early 1900s, a horse named Hans was said to be able to solve simple math problems by tapping his hoof to represent numbers. It was later found that Hans couldn’t do math at all; he was just responding to tiny cues from his handlers.
Clever Hans demonstrates that while we might think of language as something we experience mainly through our ears, we communicate meaning using more than just sound frequencies. In his book “The Expression of the Emotions in Man and Animals,” Charles Darwin argued that the way we express and interpret emotions evolved from animals, and that our ability to recognize emotions across species is universal and innate.
Today, scientists are still debating whether Darwin was right, but recent research suggests that we do share some emotional intuition with our canine companions. Dogs are the only non-primate animals that seek out eye contact with humans. Their wolf ancestors, even tame ones, won’t look us in the eye, which is why you can never fully trust a wolf.
When reading emotions in other people, we tend to look disproportionately and unconsciously to the right side of their face. Dogs share this so-called left-gaze bias, but only when looking at human faces, not when they look at other dogs. It seems like they genuinely want to understand what we’re telling them.
We seem to understand them too, or at least we think we do. Researchers in Hungary tested people’s ability to interpret the meaning of recorded dog barks and found that many people really can “speak dog.”
What do you think this bark means?
[barking]
[barking]
Okay, that dog’s angry. That’s pretty easy. What about this one?
[barking]
[barking]
Okay, that dog wants to go for a walk. One more.
[strange noises]
I have no idea what that means.
If you think about it, this dog-human language connection makes a lot of sense. We’ve co-evolved with these creatures for the past 10,000 years or so. We’ve molded them from wolves into puppies with our hands, brains, and voices. Even if we don’t always understand each other, they’re always there to listen, and that’s the real meaning of a best friend.
Isn’t it, buddy?
[phone ringing]
Wait a second. Sorry.
Hello? Um, yeah, sure. It’s for you.
“Hello? This is Oliver.”
“Hello. This is Luna.”
“Oh, hey Luna!”
“Have you seen Vanessa? She’s been out for hours! I miss her.”
“Ruh roh!”
Um, thanks Luna! If you want to find out more about dog behavior, head on over to BrainCraft and find out if they really miss us when we’re gone. Stay curious. Good boy. Oh, and special thanks to Oliver.
