Dognition, launched last week, is essentially an intelligence test for dogs. The brainchild of Brian Hare, an anthropology professor and director of the Canine Cognition Center at Duke University, it consists of assessment questions (e.g. "Does Benjy ever 'intervene' in an argument between other members of the household?" "When you laugh, does Benjy wag his tail?") and simple games involving plastic cups, treats, paper and sticky notes.
