New research from the University of Saskatchewan dives into the evolution of dog diets in a new study. Dr. Robert Losey, a professor from the University of Alberta said that "dogs evolved from wolves somewhere in Europe and Asia during the ice age." According to this study, it was assumed that dogs evolved to eat grain-rich diets due to genetic adaptation. Today, there are clues that suggest dog diets were much more diversified. Dr. Robert Losey tells us more.
