The Science Behind Dog Head Tilting.

A recent study in Hungary found that dogs may tilt their heads as they remember details they find meaningful, particularly related to sounds they have learned to find important. The study also found that gifted dogs tilted their heads 43% of the time when asked to retrieve a toy by name, while other dogs tilted their heads in only 2% of these cases. The favored side of the tilt differed from canine to canine, suggesting that one side of the brain of each dog may favor the mental activity underlying head-tilting.
