Check out this dog and their owner doing some pretty amazing thins with a tennis ball. I have two dogs and it is hard enough for me to get them to not jump on everyone that comes into the back yard. Maybe I need to call this guy and find out what he does to make his dog so smart. Do you know a dog this well trained?
