The St. Bernard or St Bernard (UK: /ˈbɜːnəd/, US: /bərˈnɑːrd/) is a breed of very large working dog from the western Alps in Italy and Switzerland. They were originally bred for rescue by the hospice of the Great St Bernard Pass on the Italian-Swiss border. The coat can be either smooth or rough; the smooth coat being close and flat while the rough is dense, flat, and more profuse around the neck and legs. The colour is typically a red shade with white, or a mahogany brindle with white. Black shading is usually found on the face and ears. The breed is strikingly similar to the English Mastiff, with which it shares a common ancestor known as the Alpine Mastiff. The modern St. Bernard breed is radically different than the original dogs kept at the St. Bernard hospice, most notably by being much larger in size and build.
