Hardcover Edition is printed in Full Color Bernese Mountain dogs are the second-largest breed of Sennenhund-type dogs, a group of four breeds developed to assist the herders and dairymen of the Swiss Alps in their daily lives. Not only did Sennenhund dogs like the Bernese Mountain Dog guard livestock, but they also protected the homestead and provided herding and drafting services. Modern-day Bernese are more likely to play the role of devoted companions than farm dogs-a role they excel at due to their affectionate and docile natures.All four of the Sennenhund breeds are hardy, good-natured working dogs with striking tricolored coats, but only the Bernese has gained widespread popularity in the United States.
