Bigger Dogs are Smarter Than Smaller Dogs in Some Areas, Study Finds
It turns out bigger dogs are smarter than smaller dogs on certain measures of intelligence, finds a University of Arizona study of 7,000 dogs from 74 different breeds.
Larger-brained dogs have better short-term memory and self-control than smaller dogs. But, in terms other types of intelligence, big dogs didn’t necessarily perform better. Brain size didn’t predict each dog’s ability to follow human pointing gestures or a dog’s physical reasoning ability.
The lead study author says the jury is out on how brain size may relate to cognition.
