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.
Descended from the English Cocker Spaniel when the latter were brought to the United States in the late 1800s. American hunters wanted a smaller dog for bird hunting, so they crossed them with smaller spaniel breeds. The English and the American Cockers were considered the same breed until 1935 when the American Kennel Club officially separated them into 2 distinct breeds. After this the American Cocker’s popularity increased dramatically. To this day they are one of the most popular breeds in the U.S. Recently their popularity has spread back to England. The American Cocker Spaniel has evolved from a hunting dog life to a very popular family pet.
