Few people would think to study human health by devising an intelligence test for dogs. But that’s the ultimate goal of new research suggesting that dog intelligence works similarly to that of humans, BBC reports. In a study published this month in Intelligence, researchers tested 68 border collies on tasks such as navigating around a transparent barrier and following human pointing. Dogs who did well on one task tended to do well on others, suggesting that some dogs are smarter overall. Humans with high general intelligence tend to live longer, but the links between intelligence and health are hard to study in humans because of variations in lifestyle. If researchers can develop a reliable IQ test for dogs, they can use dogs to study these links while controlling factors like diet and exercise, according to the researchers.
