Are English Mastiff and Volpino Italiano both types of dog?
English Mastiff The English Mastiff is a breed of extremely large dog (often known simply as the Mastiff) perhaps descended from the ancient Alaunt and Pugnaces Britanniae, with a significant input from the Alpine Mastiff in the 19th century. Distinguishable by enormous size, massive head, and a limited range of colours, but always displaying a black mask, the Mastiff is noted for its gentle and loving nature. The lineage of modern dogs can be traced back to the early 19th century, but the modern type was stabilised in the 1880s and refined since. Following a period of sharp decline, the Mastiff has increased its worldwide popularity. Throughout its history, the Mastiff has contributed to the development of a number of dog breeds, some generally known as Mastiff-type dogs, or, confusingly, just as "Mastiffs".
Greater Swiss Mountain Dog The Greater Swiss Mountain Dog (German: "Grosser Schweizer Sennenhund" or French: "Grand Bouvier Suisse" ) is a dog breed which was developed in the Swiss Alps. The name "Sennenhund" refers to people called "Senn" or "Senner", dairymen and herders in the Swiss Alps. Greater Swiss Mountain Dogs are almost certainly the result of indigenous dogs mating with large mastiff types brought to Switzerland by foreign settlers. At one time, the breed was believed to have been among the most popular in Switzerland. It was assumed to have almost died out by the late 19th century, since its work was being done by other breeds or machines, but was rediscovered in the early 1900s.
