What is an American Bully?

The American Bully is a UKC-recognized breed developed quite recently (the 1980s). 

While the foundational stock differs between lines, the breed commonly has ancestry from the American Pit Bull Terrier, American Staffordshire Terrier, American Bulldog, French Bulldog, and Neapolitan Mastiff. 

Our reference panel includes registered dogs of all these different breeds and registered American Bullies, and we see distinct genetic signatures in each breed population. However, due to open stud books and frequent cross-registration between breeds, the American Bully breed is still very genetically diverse and can have a wide range of appearances.
