Looks like border collie/pitt mix to me. Cute pup,

It's almost certainly a mix. His eyes and ears say "pitbull" and the general form and marking say "border collie".

Pitbull/border collie

Mixed breed. Almost certainly part pitbull, because pitbull is ubiquitous in US rescue dogs these days. I think there's also a chance of some hound and maybe collie. I think your best answers would come from a breed test.
