Mo is such a happy dog, and one of the few I’ve met who can actually smile. When he sees you, he pulls back his upper lip and wags his tail! Mo is a very loving dog, and the only thing he loves more than smiling is sitting on your lap! Like all big, happy dogs, Mo has not realized his size. And he doesn’t care! He will find a way to snuggle, even if it means happily squishing you in the process.
