📖 Breed History
The American Mastiff is a newer breed that has its roots in the Mastiff dogs, which have been around for centuries. Originally bred as English war dogs, they were known for their ferocity and tenacity in attacking enemy soldiers. During times of peace, they were used to guard wealthy estates and even trained in bear baiting. However, over time, their aggressive traits were bred out, resulting in a more gentle and docile temperament.
Mastiffs arrived in America with colonists on the Mayflower and were primarily used for protecting families, livestock, and property. Unfortunately, inbreeding issues began to arise, leading to health complications. To address these problems, a breeder named Fredericka Wagner from Piketon, Ohio decided to create a new Mastiff breed. Starting in the late 1980s, Wagner carefully crossed the Anatolian dog with the Mastiff, gradually breeding out the undesirable traits. The result was the American Mastiff, which had a tighter lip line and drooled less than its parent Mastiffs.
By the late 1990s, Wagner stopped outcrossing and focused on breeding within her existing dog lines. In 2002, she established the American Mastiff Breeders Council, allowing a few other breeders to join. Currently, there are only 11 breeder members in the council, and they work diligently to ensure the health and temperament of their dogs. While there is still debate about the American Mastiff’s qualities, it is undeniable that breeders have successfully created a gentle giant with excellent health and temperament.
