Summary
About Saint Bernard
Large, gentle mountain dog developed by Swiss monks for rescue and companionship. Calm and affectionate, especially with children, but very big, drooly, and heavy shedding. Needs moderate exercise, careful joint and health management, and close inclusion in family life.
About Spanish Mastiff
Large, powerful livestock guardian, calm and observant yet strongly protective. Quiet and laid back at home if well exercised, deeply loyal with family and usually reserved with strangers. Independent and thoughtful, it suits experienced owners with space, structure and early socialisation.
