I definitely see Border Collie... just something in the shape of her face, and in her eyes - regardless of coloring. I know how annoying it is when anyone with a black and white dog assumes it's part BC, but to me, she looks it. The coat would make perfect sense, too.

I think that when Border Collies are mixed with radically different breeds (like Pitties), the BC traits tend to be scarce. I know some one with a confirmed BC x Pittie, some one who knows both of the parents, and his dog looks strikingly similar to that girl! Even less Border Collie-esque, actually. : ) She's super cute, I hope she finds a home soon. And you're awesome for trying to help her. The other boys are adooorable, too! OMG. I LOVE the mix... You aren't far from Cali, are you?
