What is his breed?

Mistersquiggles

Yeah, I was going to say American Staffordshire Terrier American Staffordshire Terrier Information and American Staffordshire Terrier Pictures

PitsandPugs

Definitely a Pit mix....I'm not sold on the lab part but maybe.

She could also be pit and XX mix...lab/shep lab/BC mix...etc

I'm going to go against the grain and say pitt/border collie. I think he's way too fined bone to be pitt/lab only-both breeds have thicker chests and leg bones I think border collie fits the color and ear type as well as finer bone structure but as with all mixes-it's just guesses

Anyways-gorgeous dog
