Today, the American Pit Bull Terrier dog breed has many different lines that originated from the same ancestors. However, dog breeders took these pitbull bloodlines in many different directions. For instance, the American Bully Pit Bull is bred to have the look of a ripped athlete and the temperament of a family dog. The American bullies in the XL classes weigh in over 120 lbs in some cases.
You also have the Eddington pit bull bloodline that derived from APBT’s as well. However, they were bred for weight pulling competitions. Some of the Eddington dogs weigh in over 130 lbs. They are definitely up there with some of the biggest pitbulls in the world.
Then we have the watchdog bloodlines. The watchdog pitbulls are some of the biggest of them all. This line was originally bred from game dog lines that included Mason and Carver to name a few. They were created as a means of a hog catching dog. They were bred to be strong and athletic and have the strength and agility while still carrying a great deal of size.
As with any dog this large, it would be a good idea to start them on a joint supplement for dogs to prevent joint issues when they get older. A joint supplement that contains glucosamine and chondroitin can prevent certain issues such as hip and joint pain, arthritis, as well as hip dysplasia.
