An XL Bully is a modern breed of dog, specifically the largest variation of the American Bully breed. The American Bully itself is a crossbreed that was developed in the 1990s and is closely related to the Pitbull Terrier, with additional crossbreeding with other breeds such as English Bulldogs and Olde English Bulldogs. The XL Bully is not recognized as a breed by the UK Kennel Club, as it is a crossbreed.
The XL Bully is known for its large size and weight, with males typically weighing between 70 and 130 pounds and females between 70 and 130 pounds. However, these sizes and weights are for the show ring, and many XL Bullies available for sale can be even heavier and taller, with weights exceeding 150 pounds. The breed is muscular, powerful, and has enormous strength.
Temperament in adult XL Bullies is highly dependent on training, and the breed can be demanding, requiring proper training and socialization. They are often bred as family dogs and can adapt well to socializing and meeting new people.
