The Alpine Mastiff was, along with the Tibetan Mastiff and Caucasian Shepherd Dog, one of the earliest breeds of dog to reach truly gigantic size. It was one of the very first true mastiffs, originating in northern Europe before 500 B.C. The largest individuals may have reached more than 1 m (39 in) tall at the shoulder and weighed 160 kg (350 lb) or more, surpassing the modern Saint Bernard and English Mastiff in size.
