Saint Bernards trace back to the Great St Bernard Hospice on a high Alpine pass between Switzerland and Italy, where monks kept them from the late 1600s to find travelers lost in snow and fog. Today's Saint is a giant, massive-headed dog of roughly 120 to 180 pounds, in a shorthaired or longhaired coat, always white with red or brindle markings.
Saints are known as calm, patient and gentle, and many are good with children. Living with one still takes planning, because they shed heavily, drool and tire quickly in warm weather. Early training matters, since a friendly giant can still pull you off your feet. Their lifespan of 8 to 10 years and giant-breed health risks mean budgeting for joint care and vet visits.
