Saint Bernard
Origin: Switzerland, Middle Ages
Weight: 110-180 lbs
Height: 24-29 inches
Saint bernards are amazingly big and easygoing dogs, but due to their impressive size they can look a bit awkward. They are quiet and peaceful, love children and are not built for active and rapid games. Saint bernards will need all of your attention, so if you spend days in the office, this dog is not for you. They are tremendously strong and, of course, they require a good bit of space.
Most likely, the ancestor of the Saint Bernard was the Alpine Mastiff, which was a pretty aggressive breed. They were used as working dogs and scouts. Nowadays they are considered excellent home companions.
