The Story
The Greater Swiss Mountain Dog is the largest and oldest of the four Swiss Sennenhunde breeds, believed to descend from mastiff-type dogs brought to Switzerland by Roman legions over 2,000 years ago. The breed was virtually unknown outside Switzerland until Professor Albert Heim began documenting it in the early 20th century. The Swissy was a working farm dog used for drafting, herding, and guarding. Today they are loyal family companions and competitive cart-pulling athletes.

Fun Facts
The Swissy was nearly extinct in the early 20th century — Professor Albert Heim identified only a handful of pure specimens in 1908, and his advocacy is credited with saving the breed.
Greater Swiss Mountain Dogs are competitive cart-pulling athletes — at drafting competitions they can pull loads far exceeding their own body weight.
Despite being the largest of the Sennenhunde, the Swissy was historically the most widely used as a working dog.
