The breed derives from red-nosed American Bulldogs that were owned and bred by Rev. Scott L. Amos Sr. and his international breeding program “S. Amos American Bulldogs/Free-Style American Bulldogs”. Originally, the breeder’s intention was to compose a quality bulldog of distinct color and beauty while maintaining diverse functional working structures and abilities. Additional characteristics that were preserved through breeding were the bulldog’s naturally protective prowess, free-producing sires, free-whelping dams, and natural coursing ability.

The Red-Tiger Bulldog breed is recognized by its principal/parent registrant the “Red-Tiger Bulldog Registry and Archive”, The Canine Bodybuilding Association, the American Canidelogical Kennel Club and the Dog Registry of America, Inc.
