Bison is an 8-year-old mastiff-mix who has it all!  He’s super-smart, fully trained, and knows multiple commands.   This lovable lug is great with people of all ages, but he’d be best in a family with kids 13 and up.  He loves kids, but he doesn’t know his own strength or size when he gets excited, so he may knock them over.  (And watch out for his tail!) Bison is a very social dog with people, but must be the only pet in the family.  If you’re looking for a loving and happy companion, come adopt Bison, A079397.
