This is pretty much what an American Staffordshire Terrier looks like, they are famous for that smile.

They are also famous for destroying things as puppies.
Mine tore apart the old couch we had on the back porch for him to sit on.
So we threw it away and sourced another free one from the side of the road.
Which he then tore to shreds.

Incredible animals; love humans, hate other dogs, need training.
