My pup will get the tennis ball at the dog park, drop it through the fence, then cry and bark like there's no tommorow. Drama dog. All the other dogs will come over to see what's going on. I get to walk around and fetch it. He will also bring ball to strangers drop it in front of them and demand they throw it. Despite that OCD chase impulse he will walk a few feet past rabbits in the back yard.
