The St. Bernard is one of the giant dog breeds. He is tall, majestic, masterful, strong and muscular. The first body builder of the dog world? Not exactly, but this dog has energy and stamina, perfect for all his past jobs, including farming, watchdog and, of course, search and rescue. St. Bernards are also very active (you should probably walk yours twice a day) and love to be involved. Sorry, folks. As far as we know, they don't do laundry?
