A breed of very large domesticated dogs, weighing an average of 90 kg but often more. They were originally from Switzerland, France, and Italy, where they were developed for guarding and herding livestock, hauling loads, and for search and rescue, from which they earned their reputation, the breed name coming from two hospices on the two St Bernard Passes in the Alps. They are renowned for being calm and gentle, provided that they are well trained and socialized.
