Knuckles is 3 years old. He currently lives with a small miniature doberman, and seems to do well with small dogs. He is NOT a cat guy. He loves going for rides in the car, and also loves going for walks. He would do well in an environment with older kids, or an active couple that could keep him busy and help him use up his energy as he is still a young guy. He is well-behaved, and house trained. He walks well on a leash, and he knows sit and lay down commands.
