Dogs spontaneously process basic numerical quantities, using a distinct part of their brains that corresponds closely to number-responsive neural regions in humans, finds a study at Emory University. “Our work is the first to show that dogs use a similar part of their brain to process numbers of objects as humans do — and we’ve shown that they don’t need to be trained to do it,” says Gregory Berns, Emory professor of psychology and senior author of the study. Biology Letters published the results
