More: Even for a puppy Knoxville is the most loving, relaxed, playful, one of a kind dog. My family and I always had Golden Retrievers growing up, and he is my first dog. He absolutely loves swimming, I’ve never seen a dog love the water as much as he does. He loves sticking his head out the window during car rides and playing with his brothers (my parents have 2 of his brothers from the same breeder, just different litters) Knox has only been in my life for 7 months and I couldn’t imagine my life without him.
