History

The American Mastiff was developed by Fredericka Wagner. She constructed the breed in Piketon, OH after crossing an English Mastiff with a dog thought to be an Anatolian Mastiff or Anatolian Shepherd. After much selective breeding, Fredericka Wagner was able to create Mastiff puppies with a tight lower lip line and a dry mouth.
