One line is the dry-mouthed American Mastiff, developed by the Flying W Farms kennel. Flying W Farms had bred English Mastiffs for decades, but noticed several negative health characteristics incumbent within the breed, namely hip dysplasia, excessive drooling, a shorter lifespan, and chronic elbow and knee problems, although it's important to keep in mind that not all English Mastiffs suffer from these ailments. During World War II, English Mastiffs nearly vanished from England; with resources limited due to the war effort, it became unpopular to feed a dog quantities of food that could feed an active soldier. Following the war, the English Mastiffs breed began to recover in North America, but perhaps due to the dramatic narrowing of the breed's bloodlines, many of these negative health traits began appearing more frequently. In order to correct these faults, Flying W Farms crossed the English Mastiff with an Anatolian Shepherd and engaged in aggressive medical screening of its sires and dams.

Both lines are very new with not much breed history, making them ineligible for registration in most breed registries; registries with relaxed requirements may recognize a new breed with minimal history, such as the Continental Kennel Club's recognition of the Flying W Farms line.
