Dognition's test measures a dog's intellect in several aspects-from empathy to memory to reasoning skills/ But don't expect it to measure your pet's IQ.) Dr. Hare, one of the venture's co- founders, says a dog's intelligence can't be described with a single number. Just as humans have a wide range of intelligences, so do dogs.

Your dog could fall into one of nine categories: Ace, Stargazer, Maverick, Charmer, Socialite, Protodog, Einstein, Expert, or Renaissance Dog. That can give you something to brag about on Dognition's Facebook page. It also can shed new light on why dogs do the things they do. For example, a Charmer is a dog that trusts you so much that it would prefer to solve problems using information you give it rather than information it can get with its own eyes. Dognition helps people understand their dogs in ways that they have never been able to do. This new understanding can enrich the relationship between dogs and their owners.
