More interesting things about the Bullmastiff

  • Dogs from the Mastiff family were used in Ancient Roman times as war dogs and gladiators, fighting bears and other wild animals. The Mastiff breed comes from these Roman Mastiffs.
  • The Mastiff of Sir Peers Legh became famous in 1415 when the dog stood over his wounded owner for hours during a battle, protecting him from the enemy. Though Legh later died, the dog became famous and founded a kennel influential in forming the modern Mastiff.
  • Mastiffs were crossed with Bulldogs (actually a breed that more resembles today’s Olde English Bulldogge, so not quite as short and wide) in the late 1800s to produce a dog who could sneak up on, catch, and subdue (but not maul) poachers on English estates.
  • The breed was dubbed the Gamekeeper’s Night Dog.
  • Dark brindle was preferred because it blended into the night.
  • Fawns later became popular with estate owners who wanted a flashy looking Mastiff-like guardian.

  • A Bullmastiff named Swagger is the team mascot for the Cleveland Browns football team.
  • Bullmastiffs appear in the movies Rocky, Rocky II, and License to Wed.
  • The Bullmastiff in Rocky was Sylvester Stallone’s own dog. The dog was named Butkus, after the football player Dick Butkus. He got the part in the movie because trained dogs cost too much and Butkus came free! Among the tales Stallone recounts of misadventures with Butkis is this one: “On our way from New York to Hollywood to seek our fortune, the heat became so intense that we had to pack old Butkus in cracked ice for two days. I promised him that if we survived, he’d someday get treated like a king. But I almost changed my mind when he practically got us killed in a wildlife preserve. An exceptionally large ostrich decided to peck him to death and attacked the car. Rather than being diplomatic, Butkus jumped out in a counterattack, and I practically got slaughtered trying to separate them. By the time I got him back in the old car for a quick escape, the thing stalled and a herd of unhappy buffalo descended and attempted to upset the car with us in it. In the middle of all that confusion, Butkus jumped in the backseat and went to sleep.”
