Inside the Dog Mind

New science reveals the multiple intelligences of mankind's best friend

Just about every dog owner is convinced their dog is a genius. For a long time scientists did not take such pronouncements particularly seriously, but research now suggests that canines are indeed quite bright and, in some ways, unique. Brian Hare, associate professor in the department of evolutionary anthropology and the Center for Cognitive Neuroscience at Duke University, is one of the leading figures in the quest to understand what dogs know. Founder of the Duke Canine Cognition Center, Hare has written a book, The Genius of Dogs (Dutton Adult, 2013), with his wife, journalist Vanessa Woods. Hare recently answered questions from Mind Matters editor Gareth Cook.

COOK: What is the biggest misconception people have about the dog mind?

HARE: That there are “smart” dogs and “dumb” dogs. There's still this throwback to a unidimensional version of intelligence, as though there is only one type of intelligence that you either have more or less of.

In reality, there are various types of intelligence. Different dogs are good at different things. Unfortunately, the clever strategies some dogs are using are not apparent without playing a cognitive game. This means people can often underestimate the intelligence of their best friend. The pug drooling on your shoe may not look like the brightest bulb, but she comes from a long line of successful dogs and is a member of perhaps the most successful mammal species on the planet besides us. Rest assured: she is a genius.

COOK: What are the “different things” that dogs are good at? What are the areas of dog intelligence you have studied?

HARE: We know that, as a species, dogs are remarkable in certain areas, such as taking someone else's visual perspective or learning from someone else's actions. In particular, I've been interested in how dogs recruit help. Still, most of my research with dogs has been about the cooperative way they use human communicative gestures. Or put more simply, how they can interpret our gestures to understand us or get what they want.

COOK: But other animals are intelligent, right? What makes dogs unique?

HARE: Absolutely. Other animals have their own unique genius that was shaped by nature. In the case of dogs, it happens to be their ability to 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. It allows them to be incredible social partners with us, whether it's hunting or agility or just navigating everyday life. Their ability to interpret our gestures also helps them solve problems they can't solve on their own.

COOK: I see you have created a Web site, Dognition.com. Can you tell me about it?

HARE: Dognition is about helping people find the genius in their dog. The only way to find their genius is to compare them with other dogs. As I said, different dogs use different strategies to solve problems. Does your dog rely on you to solve problems, or are they more independent? Do they pay attention to where you are looking before they decide to sneak food off the coffee table, or are they unaware when you are watching—making it hard for them to be sneaky?

Dognition is all about playing fun games that will give you a window into your dog's mind and that will in turn enrich the relationship you have with your dog. On top of that, the data that you enter will contribute to a huge citizen science project that will help us help all dogs, from shelter dogs to service dogs. Everyone who signs into Dognition will not only get an extensive cognitive profile of their own dog, but the data will also be entered into a database that scientists can use to answer all these burning questions that we have never had the resources to answer, such as about breed differences. The largest single dog study published tested around 15,000 dogs. With Dognition and people's input, we have the potential to test hundreds of thousands or even millions of dogs. It's an incredibly exciting project, and I can't wait to see what we find out.
