History

American Mastiff History & Lineage

This breed comes out of Piketon, Ohio, where they were first bred by Fredericka Wagner in the 20th century by interbreeding the English and Anatolian Mastiffs. By the late 1900’s, Wagner had enough stock to breed from existing lines, rather than continuing to outcross and in 2000 the breed was officially recognized by the Continental Kennel Club, although it remains unrecognized by the AKC and the UKC. In 2002, Wagner founded the American Mastiff Breeder’s Council for the continued preservation and documentation of the breed.

American Mastiff Medical Challenges

The American Mastiff appears to be at risk for many of the same problems seen in English Mastiffs, such as joint dysplasia, heart problems, arthritis, bloat, eye problems and dermatological problems, although they are less prone to developing them. Most American Mastiffs live full and healthy lives without much issue. Annual checkups with your veterinarian will help you to better understand and ensure the health of your American Mastiff as they grow and age and they will appreciate the loving care you provide as much as you appreciate them.

We have the unique opportunity to grin and grow—together and share joy along the way.

This site is for dog owners and lovers—moms and dads and brothers and sisters…and every other member of the extended family. With your help and support, it will become the #1 trusted resource for dog owners and a place for us to learn, laugh and love everything about our dogs and how they inspire us.

Together, we’ll create those uplifting “championship moments” along the way.
