The history of the American Mastiff is entirely tied to the old European Mastiffs but in particular the English Mastiff. The developers of the American Mastiff crossed the English Mastiff with the Anatolian Mastiff at the Ohio kennel, Flying W Farms. The founder of this breed is Fredricka Wagner. Because of this the English Mastiff and the American Mastiff look very much alike. The difference between the two is that the American Mastiff was bred to have less health concerns than the English Mastiff and without the drooling. In 2000 the CKC acknowledged that the American Mastiff and the English Mastiff were separate breeds.
Ancestors of the Cao da Sera de Aires were used for herding livestock in the Serra de Aires and Alentejo, Portugal. This herding dog is native to Portugal and throughout the 20th Century he was kept as a working dog.
Known also as the Portuguese Sheepdog, Portuguese Shepherd Dog or Serra de Aires Mountain Dog, there are some questions surrounding the breed's ancestry as there are few records of dogs before 1900. The dog is thought to be related to the Pyrenean and Catalan Sheepdogs and that it has descended from Briards which were imported into Portugal and crossed with the Pyrenean Sheepdog.
The Cão da Serra de Aires breed standard was accepted by the Portuguese Kennel Club, and the breed was recognized internationally in 1996. The dog was also recognized by the United Kennel Club in the Herding Group in 2006.

This is of particular importance to breeders so as to prevent the parent dogs passing bad genetic conditions to the puppies.

The wrinkles in your dogs; face, around the eyes and muzzle must be kept clean as they can become infected if you don’t.

The Cao da Serra de Aires may have long hair but he isn’t high maintenance. He won’t require professional grooming, but will require a good brush a least twice a week. This is because the long coat can tangle.
