While the American Bulldog is all one breed, it does actually come in four distinct variations, as well as a variation referred to as a “hybrid,” which is a bred combination of any of the other four types. These bulldogs vary in appearance and structure, but all of them maintain the basic characteristics of the breed in general.
The Standard American Bulldog (also known as the “Performance” American Bulldog or the “Scott” American Bulldog) are less wrinkled than their counterparts, with smooth skin across the skull. Standard American Bulldogs are often mistaken for Pit Bulls because of their smooth, wide-set heads. Their snouts will be a bit longer than other types of American Bulldog and they are typically taller, as well. This is the faster variety that has developed a reputation as being aggressive, though proper training can stop any potential negative behavior.
Old Southern Bulldogs are pure white. They are referred to as White English Bulldogs, as well. While they are more wrinkly than their Standard counterparts, they are still larger than the regular English or British Bulldog. They are often named the “true” kind of American Bulldog and are mated with the other variations to keep the breed close to its roots.
The Margentina Bulldog, also known as “The Painter,” are the smallest version of the Bulldog. The Margentinas are stronger and were initially bred for use in dog fighting. This version of the breed is supposed to be significantly more aggressive than other American Bulldogs. It is even said that Margentinas were cross-bred with Pit Bulls to help increase their strength and aggression, but this could just be an urban myth. Margentinas, because of their nature and use in fighting, are often inbred by irresponsible owners.
The Classic American Bulldogs are technically called Johnson Bulldogs. These are the variety that most people think of when they picture an American Bulldog, being far larger than their counterparts and having a stunted muzzle. Johnson American Bulldogs also have wrinkling in the face and soggy lips, the way a typical bulldog is stereotyped.
Hybrids are any combination of these four types, and are often healthier dogs. Hybrids cannot have been inbred, as their mares and sires have to have differing bloodlines and features. The distinct lack of inbreeding in hybrid American Bulldogs leads to less health and temperament issues. Hybrid bulldogs are often bred to produce only desirable traits and reformulate new versions of the American Bulldog, usually with less aggression or potential health issues. The Classic and Standard American Bulldogs are the most common mix for a hybrid.
