Understanding the difference between a purebred American Bully and a mixed American Bully is important for anyone buying, breeding, or researching the breed. It affects everything from appearance and temperament to health and predictability.
Many people confuse the two because they can look similar at first glance—but genetically and structurally, they are quite different.
