English Bulldog
English Bulldogs originally were used to drive cattle to market and to compete in a bloody sport called ‘bull-baiting'.
If you're not familiar with that term, a variant of bull-baiting was ‘pinning the bull', where specially trained dogs would set upon a bull one at a time.
A successful attack resulted in the dog fastening his teeth strongly in the bull's snout.
It sure doesn't seem like this dog would be able to do this at all. But, alas, the Bulldog was bred especially for this sport.
However, many of us know the English Bulldog as being a brawny little powerhouse whose characteristic crab-like waddle exudes great strength, stability and vigor.
Their average height measures 17 inches (43 centimeters) in full-grown males and they can weigh anywhere from 45 to 60 pounds (20 to 27 kilograms).
