Is my staffy pup a cross breed?

Hi all can someone confirm if my staffy looks like a cross breed. He is nearly 5 months now, some people have said his ears are too big or his mouth too long to be a full staffy.

He is a handsome boy, maybe something else in him but until he matures some more it's difficult to say! I'd say more staffie than anything, but it doesn't matter if you've lost your heart to him

Jen.. my boy has well and truly stolen it.. even though he tried to kill himself last week.

He ate a hole into his bed whilst we was all out, somehow managed to get his head through and it was all wrapped around his neck. He was lay there on the floor and his eyes was all bloodshot hardly moving - he soon bounced back to normal after we cut him free. I dread to think what would of happened if i was out any longer

Oh, silly boy! 

As already said , at 5 months it's so hard to say - there is still so much growing & muscling up to do! And he may grow into those gorgeous ears. 

He's certainly got a LOT of Stafford in him & he could well be full staff. 

I take it he isn't a registered pedigree?
