Bear

Bear is a large Mellow Chowchow mix of sorts- a guardian member of the Poochie Posse. He is very easy-going until you want to mess with any of his friends. 

Bear is the largest member of the Poochie Posse, Right Next to Vincent. Unlike many of the dogs in the posse, Bear has no interest in Celestine romantically, and only sees her as a friend.
