There was the recent altercation between mascots (UGA vs Bevo) and it made me half remember something I read about bulldogs.  Turns out they were bred specifically for attacking bulls, hence the name.  Maybe Bevo knew what he was doing after all.

The designation “bull” was applied because of the dog’s use in the sport of bull baiting. This entailed the setting of dogs (after placing wagers on each dog) onto a tethered bull. The dog that grabbed the bull by the nose and pinned it to the ground would be the victor. It was common for a bull to maim or kill several dogs at such an event, either by goring, tossing, or trampling. Over the centuries, dogs used for bull-baiting developed the stocky bodies and massive heads and jaws that typify the breed as well as a ferocious and savage temperament. Bull-baiting, along with bear-baiting, reached the peak of its popularity in England in the early 1800s until they were both made illegal by the Cruelty to Animals Act 1835.
