Saint Bernards come from the Great St Bernard Hospice, high on the Alpine pass between Switzerland and Italy, where monks kept them from the late 1600s to find travelers lost in snow and fog. Today's dog is a giant, usually 120 to 180 pounds, with a massive head, a wrinkled brow and a white coat marked with red or brindle. Both shorthaired and longhaired coats are double coats.
That Alpine heritage matters on the Texas coast. A dense coat built for snow holds heat, so most Saints do best as indoor dogs here. Expect heavy shedding, drool and a big appetite, plus early training so a friendly giant doesn't pull a leash out of your hand. They're patient and often wonderful with children, though each dog varies.
