Thunder came in as a stray, so his history is incomeplete but he LOVES tennis balls! He is high energy so training based on positive reinforcement and an active home will help. Thunder lived with a child and was overly jumpy, and while he has been around cats, he was reported to be too rough for them; so we would recommend a mature home without cats. He has not lived with other dogs but shows interest. Slow, controlled intros would be ideal.
