Can anyone help me with the breed of my dog?

My dog looks like a staff. He is still very young I would say about 2/12.
Basicly ive had him for about 1/12 now and he is a rescue dog. He obviously came with no papers so know nothing about him eg the day he was born how old he actually is etc. Anyway prince is a white dog with what looks like a ridgeback going down the back of his neck. He looks like a staffy and had got spotty black ears. Can anyone help please ?/

I can MAYBE help u if u send me a pic of him contact me at [email protected]
