Chewy will sometimes bite my son Mike. We don't knw why but if Mike tries to correct him he sometimes will...
Mike started putting Chewy in the bathroom for about 4 minutes with the door closed as punishment. The first time he did this he had to keep putting chewy back...4 times!

But the 4th time he came out he was very nice to Mike. Mike also gives him treats to win him over... this seems to really be helping alot.
When we got Chewy Mike was heading off to college and was never here. Then he came home and Chewy was trying to be Mike's boss I think? Mike never hurts chewy or mistreats him so this is all we can guess... Chewy also Likes Mike and will play with him and sit on his lap.
