Canines got their love of running, chasing, and catching fast-moving objects from their wild ancestors who needed those skills for survival. Once they were domesticated, many dogs, including the working breeds, like Labradors, golden retrievers, spaniels, hounds, and pointers, were specifically bred to retrieve certain items for their human owners. These dogs still have the urge and ability to fetch ingrained in their genes. That desire is reinforced when we praise them and/or offer positive reinforcement treats.
