Everyone likes to believe that his or her dog, or breed of choice, is the smartest. But, because of their breeding and history, some breeds just tend to be smarter than others. Herding and working dogs tend to have higher levels of intelligence and trainability than do some hunting and toy breeds. While there is not technically a dog version of an IQ test that can be used to determine a dog's exact intelligence level, studies have been performed and opinions polled to come up with criteria for determining a dog's smarts. One such study, conducted by a psychology professor, named Stanley Coren, ranked dogs using responses and assessments provided by obedience trail judges. Intelligence levels were determined based on their understanding of new commands, as well as their obedience to commands issued to them. Based on history of the breeds, findings from studies and obedience assessments like the one conducted by Coren, we've compiled a list of the top 10 smartest dogs to settle the debate.

Border Collie

Like many herding dogs, Border Collies are highly intelligent and trainable. They were bred to complete complex tasks, both with and without human direction.
