We got this guy as a puppy 4 weeks old. He was adopted at 8 weeks old. He was returned to us at 4 months old because he was out of control. To be fair, this was an older lady who never got control of her puppy from the start. He was lonely and needed a playmate. I think he would have been fine. He loves to play with the other dogs. He likes to run the yard. He has not had any accidents in the house. He is working on his manners. I make him sit before I walk out a door. He is current on his puppy shots.
