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.
Also known as the Cao da Serra de Estrela, the large Estrela Mountain Dog from Portugal is an ancient breed, having been used for centuries to guard homesteads and livestock.
The Estrela, as a herding dog, has been developed over a long period of time because shepherds particularly wanted a dog that could survive in the mountains and be strong enough to guard livestock from predators.
The first official recorded breed standard was published in 1933, with an attempt to make the Estrela a distinct breed with a hooked tail and double dew claws.
Today the Estrela is a dog which can be found in other countries beyond Portugal, and in fact in 1973 pairs of the dogs were imported to the United States.
This crossing of the English Mastiff and the Anatolian Mastiff resulted in a Mastiff with a much drier, less drooling mouth than the other Mastiffs. This is a giant, massive dog – powerful and muscular. With a wide head that is rectangular rather than square. Their eyes are dark amber, and their ears are high on their head and rounded.

Puppies of the American Mastiff are born almost black and as they grow their coat color lightens.
