Special note for English bulldogs - this breed of dog still exists primarily because veterinarians are available to perform C-sections for the puppies to be born. The narrow hips of the breed combined with the relatively large head size means the female is often unable to deliver the puppies through the birth canal - they are too big for the space. If you are planning on breeding an English bulldog, you need to plan carefully so that a veterinarian is available to perform the C-section on an emergency basis if needed. Most English bulldog breeders schedule the C-section when they know the female's breeding date.
When your English bulldog no longer shows signs of heat (in the female) or has decreasing semen quality (in the male), that is when it is too late. Otherwise, most dogs can be successfully bred for most of their adult lives.
An English Bulldog.
Really it depends on what kind of bulldog you mean. American bulldog? French Bulldog? English bulldog? Pit bulls are a very powerful breed, but again, it depends on the dog, not the breed. -- The pit bull is the most powerful breed, pound for pound.

The English Bulldog is classified as Canis lupus. All domesticated and feral dogs belong to this genus and species. They are differentiated by breed, not by classification.
The breed is "Bullmastiff" which is a cross breed from the English mastiff and English bulldog it was a reconized breed by the AKC in 1957.
The American Bulldog breed was not developed until the 1980's however, the dog breed in which they descended from was the Olde English Bulldogge. The Olde English Bulldogge ( dating back to the 1700-1800's) looked extremely similar to the American Bulldog only it had more English Bulldog characteristics (like a shorter snout) than the American Bulldog.
