The American Bully is one of the youngest breeds at the moment, which began to form in the 90s and was registered only in 2013. However, the ancestors of the bulls were known in Europe long before our era and usually served as watchmen and/or hunters, and later as fighters. Mastiffs, Bulldogs, Staffordshire, and Pit Bull Terriers – all of them had excellent strength and enviable health, but at the same time, they were aggressive enough that not all owners could cope with them.
