Bernie is so cute!! He will stop the biting as he gets older. My LeRoy was a biter when he was little but hasn't bit for months and he is 1 1/2. He also loved being under the couch and would hide his "treasures" there, especially the things he knew he shouldn't have like socks and such! My Louie never bit but I think it was because LeRoy kept that in check. Enjoy Bernie!!
