Saint Bernards trace back to the Great St Bernard Hospice, high on an Alpine pass between Switzerland and Italy. Monks kept them from the late 1600s to guard the hospice and help find travelers lost in snow and fog. Today's Saint is a giant, massive-headed dog of 120 to 180 pounds, with a shorthaired or longhaired double coat that's white with red or brindle markings.
Saints are known as calm, patient and kind, and many are gentle with children. Living with one takes planning, though. They shed heavily, drool freely and need early training, because a friendly dog that size can still knock over a child. Expect a shorter lifespan of about 8 to 10 years, and budget for joint care and giant-breed health risks. Saints vary, so each dog's own personality matters as much as the breed.
