Old English Bulldog Breed Info.

I have an Old English Bulldog breed who is almost a year old, we've had him for 10 months. He's only a first generation old english, so his mom is an american bulldog, and his dad is an english bulldog. Everytime I try to find information about this newer breed I can't find anything. Just English Bulldog information. Has anyone had any experience with this breed? Can someone give me some helpful information to use in the future? I can already tell you one thing, he's EXTREMELY stubborn! Anyone one have any suggestions?
