Bigger dogs outdo little dogs at this one intelligence test.
Bigger dogs, with larger brains, perform better than smaller pups on certain measures of intelligence, new research shows.
Larger-brained dogs outperform smaller dogs on measures of executive functions—a set of cognitive processes that are necessary for controlling and coordinating other cognitive abilities and behaviors. In particular, bigger dogs have better short-term memory and self-control than smaller ones, according to the study in Animal Cognition.
