The Alapaha Blue Blood Bulldog is a breed of bulldog from the United States, and it is predominantly used as a guard dog. It is a very powerful, muscular breed with large head and brachycephalic muzzle. The hair coat is short, typically colored white with black, blue, buff or brown patches, and its tail is kept un-docked. Sexual dimorphism is common in the breed, with larger dogs typically twice the weight of smaller bitches.
The Alapaha Blue Blood Bulldog is a rare breed that is believed to be descended from Old English Bulldogs that were brought to the Americas in the 18th century where they were used in the blood sports of bull baiting and bear baiting; they were later used as cattle and pig herders. For multiple generations, the breed was bred solely by the Lane family of Rebecca, Georgia. They eventually started a breed registry with a dog called Otto, the foundation dog of the family’s breeding operation. The dog’s name has occasionally been used as a nickname for the breed. In the early 21st century, there were an estimated 120 to 150 extant Alapaha Blue Blood Bulldogs.
