We need more pic's to really tell. But I would call him other things before Pit.
Adorable pup!! Thanks for rescuing him!!
What a cutie!
I would say no to the pitbull statement.
Doesn't look like any time of bull/terrier to me, like I said I think he is a Collie-Hound mix. Wonder what gives your friend the "pitbull" impression..... Glad to hear that he's doing better now!
