If you're reading this it's probably because you love Bull Terriers, but then again, who doesn't.
In 1907, "eminent dog authority" Robert Leighton wrote in "The New Book of the Dog": The Bull-terrier is now a gentlemanly and respectably owned dog, wearing an immaculate white coat and a burnished silver collar; he has dealings with aristocracy, and is no longer condemned for keep bad company. But a generation or two ago [that would be about 1860] he was commonly the associate of rogues and vagabonds, skulking at the heels of such members of society…" p 329.

The historical record remained, but the dog's shape didn't (nor did the hyphen in the name). Bull Terriers have been redefined over the last hundred years. The photos below show how much the skull has changed.
Breed standards from 1900 and 2014 describing the head.
It wasn't an abrupt change as these photos show.
