What flavor of pitbull is my bog?

This is my sweet baby Lola. She was a rescue from a backyard breeder and is my entire world. She is definitely a shorty and weighs like 70 pounds. She could do with losing some chonk so we are working on that.

She does not have any official breed information other than pitbull. But I have never seen a black and white American pitbull before. She has received many compliments about this because she is a very pretty girl.

What do you guys think she is? A staffy perhaps? A bully?
