More: I rescued Buck from a puppy mill in 2010 and he’s been at my side ever since - literally, stuck to my side. I believe if you treat it like a dog it will act like a dog. So, after our first puppy class, we continued socializing and training basic obedience and outdoor agility on full-size equipment and he easily earned a good citizenship certificate. At 14, Buck continues to be an outstanding representative of an often undertrained and misunderstood breed.
