How clever is your dog? A literature review sums up the evidence and if dogs were clever enough to understand, they wouldn’t be happy
A literature review carried out by researchers at the University of Exeter has reached a conclusion that may upset millions of pet owners: the combination of many different studies of animal intelligence suggest that dogs are no smarter than many other animals. You may think your pooch understands every word you say, you may believe that Rover knows exactly what is going on around him, and you may like to think that when he looks at you with his head cocked, that he has the intellectual ability of a super-smart mammal. The truth? He may be no smarter than a pigeon.
