[Whatdogami]

What sort of dog do you think this is. She's 9 months old . Dd thinks she's a staff . I think she's not. Well at least not a full staff . What fo you think ?

@tattychicken she shares many characteristics with pitbull types
Yes, four legs, a tail, two ears, two eyes, smooth coat.

I thought the first picture looked like my Staffie cross (not sure crossed with what), but the second pic less so.
She is lovely whatever she is.

A Heinz 57.
