See I dont really know. She has had him since he was a little puppy and he is now atleast 6 yrs old. She just moved here recently so I dont know too much about him. I know her mom wont even take him out and he is inside alot because he is very strong and doesnt do well with other animals. She says he is a BIG BABY but whenever I go near him or see him I just have a funny feeling about him like I could never trust him just by the look on his face and his eyes or something.
