Greater Swiss Mountain Dog Guide: Size, Temperament, Care and Adoption

Greater Swiss Mountain Dog overview

The American Kennel Club places the Greater Swiss Mountain Dog in the Working Group and lists Switzerland as its origin. The United Kennel Club describes it as primarily a draft breed, with a large, powerful, short-coated, tri-colored build.

Where does the Greater Swiss Mountain Dog come from?

The breed is traced to the Roman invasion of Europe, when Roman mastiff-type dogs crossed with local Swiss working dogs. That crossing also produced the other Sennenhund breeds, and the Swissy is generally thought to have come first among them. The breed is also believed to have influenced the Rottweiler.

How big is a Greater Swiss Mountain Dog?

The American Kennel Club puts it in its extra-large size category. On Greater Swiss Mountain Dog size, the American Kennel Club gives male height as 25.5 to 28.5 inches and female height as 23.7 to 27 inches, while the United Kennel Club gives males as 25.5 to 28.5 inches and females as 23.5 to 27 inches, and VCA Animal Hospitals gives the breed as a whole as 23.5 to 28.5 inches. On Greater Swiss Mountain Dog weight, the American Kennel Club lists males at 115 to 140 pounds and females at 85 to 110 pounds, whereas VCA Animal Hospitals gives 90 to 130 pounds for the breed overall.

Greater Swiss Mountain Dog temperament: are they good family pets?

The American Kennel Club describes the breed as faithful, family-oriented and dependable. It rates the breed at the top of its scale for family affection, openness to strangers and compatibility with children, though individual dogs vary. VCA Animal Hospitals calls the Swissy generally placid and eager to please, and says many like to cuddle with their people. The same source notes a bold streak, so owners need to show confidence and consistency. On whether Greater Swiss Mountain Dogs are aggressive, the United Kennel Club describes the breed as self-confident and watchful, agreeable and devoted to its family, and good with strangers, and its standard disqualifies viciousness.

Greater Swiss Mountain Dog exercise needs

The American Kennel Club rates the breed at 4 of 5 for energy, mental enrichment and playfulness. VCA Animal Hospitals says Swissies show considerable talent for weight-pulling and carting. Because the breed does not tolerate heat well, exercise is best kept to the coolest parts of the day.

Do Greater Swiss Mountain Dogs shed?

They have a double coat that the American Kennel Club describes as short and smooth. On Greater Swiss Mountain Dog shedding, VCA Animal Hospitals says shedding happens twice a year and regular brushing helps limit it. The American Kennel Club rates shedding at 3 of 5 and grooming frequency at 2 of 5. The same source adds weekly ear cleanings, nail care and periodic baths to routine Greater Swiss Mountain Dog grooming.

Training a Greater Swiss Mountain Dog

VCA Animal Hospitals recommends socialization and consistent, positive training beginning in puppyhood and continuing through life. The breed may be slower than most to grasp housetraining, and a crate with a steady feeding and potty schedule can help. The American Kennel Club rates trainability at 4 of 5.

Greater Swiss Mountain Dog lifespan and health issues

For Greater Swiss Mountain Dog life expectancy, the American Kennel Club gives a general figure of 8 to 11 years. VCA Animal Hospitals lists elbow and hip dysplasia, bloat, eye abnormalities and hypothyroidism as the most common genetic health issues. Ask a veterinarian what screening and monitoring suit a particular dog.

Considering a Greater Swiss Mountain Dog for adoption or rescue
