she looks like a BC/staffy to me. she does remind me a bit of Misty, who BTW has been mistaken for a Staffy/BC because she is short, square and blocky. JRT is possable in that mix too, but BCs DO come in the 15-17 height range, Misty is only 18, I met 1 smooth girl that was 15" max, probably closer to 13-14" and she was a full grown pure BC lol
