There are two types of American Bulldogs, Johnson and Scott. The standard/Painter American Bulldog is considered the working dog that Farmers/Ranchers used with livestock, hunting, and ranch work. It is believed to be the dog that was bred and developed on American soil, but that does depend on the theory of ancestry you prefer. It is lighter in weight than the Johnson, muscular, and has agile movement.... (read more) It has longer legs and a longer muzzle with better breathing. The Johnson American Bulldog was developed from the Standard/Painter American Bulldog with other bully breeds bred into it which over time has produced somewhat of a giant extreme bulldog type. Both are American Bulldogs and both have there pros and cons. However when you breed for something between the two types Standard/Bully it is generally labeled a Hybrid because you are trying to combine some of the better characteristics from both of them. To accomplish this type of bulldog we have crossed the Johnson American Bulldog and another American Performance Bully. Our puppies are 80% Johnson type and 20% Performance Bully. Once you meet our bulldogs in person and see them first hand for yourself youâ€™ll surely like what you see. I hope I have addressed your curiosity in enough detail. Please let me know if I can be of any further assistance.
