 These dogs were originally used in blood sports such as bull baiting, and dog fighting - a bloody entertainment introduced by the British to the Indian subcontinent.When the blood sport was made illegal across the Empire, the Gull Terriers were used as guard dogs.In colonial India, some breeders crossed the Gull Terrier with the Bully Kutta, naming the progeny the "Gull Dong", which "is celebrated in India and Pakistan for its speed and tenacity".
