Your boy is beautiful. OEBs usually live longer and have fewer health problems than EBs. They are usually longer and taller and most are born with tails that are docked when they are 3 days old. Genetically they are EB, Bull Mastiff, American Bulldog, and ??, I think Pit Bull. They breed and whelp naturally, no c-section. They are mostly EB, have the same sweet temperament but don't have the breathing issues because their airways are bigger.
