He had to have been someone's pet as he is housebroken and wears a collar well and walks on a leash. He has a some food aggression but I think that will calm down after he realizes he is going to be fed on a regular basis. He is so sweet and gentle, loves to be petted and cuddled and plays well with the other dogs. I just had to give him a chance. If it doesn't work out for him, at least he had it good for a while!!!
