Congrats mate, looks like a lovely dog.
I've got a Staffy, he goes by the name of Bruno. He was called that when i got him at 10months old. Every Bull Terrier seems to be named after a boxer up here (Edinburgh) Tyson,Bruno,Ali etc....
Buddy works for me, IMHO looks like it'd suit him too. He looks like he'll be a belter with a bit of feeding up and lotsa nice walks.
Look after him and he'll more than look after you.
