Just to clarify here, by English Bulldog you mean the short squatty ones. They, by reputation, have been overbred and bred into a corner. The owners want the wide front legs, recessed nose and protuding lower jaw. All these things can be health hazards affecting their walking, breathing and eating.
You might want to check into the American Bulldog. This breed is the closest representation of the original English Bulldog of the 1800's. The Am. BD is a fantastic animal.

I have been aquainted with both breeds and end up feeling sorry for every Modern English BD I meet.
They have big hearts and steady personalities but cannot even make 1 mile walk on a warm day.
I don't mean to offend with the above comments, just telling it like I see it and it is only my opinion.
