16 Ways Dogs Are Smarter Than You Think
When it comes to intelligence, dogs are at the head of the class.
They’re masters of communication
“Your dog may be able to figure out the best ways to communicate what she wants,” says Amanda Landis-Hanna, DVM, senior manager of Veterinary Outreach for PetSmart Charities. “Many dogs have different whines or barks that mean different things. She may learn that you respond to a high-pitched whine with a treat and a lower pitched whine with a belly rub.” Check out the scientific reason dogs tilt their heads.
They have an extensive vocabulary
They may not be able to respond in kind, but according to psychologist and leading canine researcher Stanley Coren, PhD, of the University of British Columbia, dogs can understand much of what you say. The average dog can learn 165 words, while those in the top 20 percent of dog intelligence can understand up to 250 words. “The upper limit of dogs’ ability to learn language is partly based on a study of a border collie named Rico who showed knowledge of 200 spoken words and demonstrated ‘fast-track learning,’ which scientists believed to be found only in humans and language learning apes,” Coren says.

They prefer dog-speak
Similar to the way that adults bond with babies using “baby-talk,” a study from University of York’s Department of Psychology found that dogs are more interested in interacting and spending time with humans who communicate in “dog-speak.” Alex Benjamin, Ph.D student, explains that dogs “need to hear dog-relevant words spoken in a high-pitched emotional voice in order to find it relevant.” Squealing “Who’s a good boy?” in your highest voice is simply a good way to bond with your pup.

They can picture what they smell
According to a study published in the Journal of Comparative Psychology, dogs create a “mental representation” of objects they are tracking through smell. Whether its a ball, chew toy, or treat, dogs make an assumption of what they will find at the end of a scent trail and are surprised if what they find doesn’t match their expectation. Using its incredible sense of smell, this dog saved a missing person in a way no human could.
They are brainier than cats
“I believe the absolute number of neurons an animal has, especially in the cerebral cortex, determines the richness of their internal mental state and their ability to predict what is about to happen in their environment based on past experience,” says Suzana Herculano-Houzel, associate professor of psychology and biological sciences at Vanderbilt University. And according to a study in which she participated, dogs possess significantly more neurons in their cerebral cortex than cats—530 million vs 250 million. (For comparison, humans have 16 billion cortical neurons.) The findings mean that “dogs have the biological capability of doing much more complex and flexible things with their lives than cats can,” she explains.
They use facial expressions to communicate
Dogs may get excited when rewarded with a tasty treat, but they are much more expressive when humans are looking at them, according to research from the University of Portsmouth. According to dog cognition expert Juliane Kaminski, Ph.D, who led the study, dogs are sensitive to humans’ attention and produce more expressions when someone is watching. “We can now be confident that the production of facial expressions made by dogs are dependent on the attention state of their audience and are not just a result of dogs being excited,” she says. The most common expression used in this research? “Puppy dog eyes” or brow raising. Learn how dogs get humans to fall in love with them.
They can tell the difference between happy and angry faces
According to a study published in Current Biology, Fido can tell when you’re mad at him for chewing your slippers even before you yell at him. “Our study demonstrates that dogs can distinguish angry and happy expressions in humans, they can tell that these two expressions have different meanings, and they can do this not only for people they know well, but even for faces they have never seen before,” says Ludwig Huber of the University of Veterinary Medicine Vienna. Dogs are even smart enough to be heroes–these shelter dogs saved their owners’ lives.
They process vocabulary and intonation like humans
They may not speak, but dogs can understand speech in a way similar to humans. They use the left hemisphere of their brain to process vocabulary and the right hemisphere to process intonation. This discovery was found by using fMRI to analyze dogs’ brain activity while their trainers’ voices offer praise in both positive and neutral ways. Here are 13 secrets to becoming every dog’s favorite human.
They can interpret our gestures
Dogs not only process vocabulary and intonation but also read our communicative gestures. “We take it for granted that dogs can effortlessly use our pointing gestures to find a hidden toy or morsel of food, but no other species can spontaneously read our communicative gestures as flexibly as dogs can,” says Brian Hare, an associate professor in the department of evolutionary anthropology and the Center for Cognitive Neuroscience at Duke University. This ability helps dogs solve problems and allows them to be our social partners, he explains.
They contagiously yawn
Contagious yawning—when seeing, hearing, or thinking about someone yawning causes you to yawn—is related to empathy in human adults. Dogs also contagiously yawn, which means they also have empathy, explains Hare in Scientific American. In fact, they probably have more empathy than human infants who do not typically contagiously yawn.
