Background and characteristics
The Greater Swiss Mountain Dog is the largest of the Swiss mountain breeds, developed on alpine farms to pull loaded carts, move cattle, and keep an eye on the property. The breed nearly disappeared in the early twentieth century and was rebuilt from a small number of surviving farm dogs, which is why it remains fairly uncommon outside dedicated circles. The working history explains the body you get: enormous pushing and pulling strength, a deep chest, and no interest in distance running.
Exercise and play
An hour of activity a day suits an adult. Two half-hour walks cover the basics, and a long hike on cool ground or some light carting work on a proper harness makes for a much more contented dog. Puppies are the exception.
Growth is fast and heavy, so through about eighteen months keep the repeated stairs, the jumping off decks, and the sprints on slick floors to a minimum, and keep the dog lean rather than filled out.
Coat and everyday care
The short double coat is easy to look at and deceptively heavy to manage. Undercoat comes out in sheets twice a year and needs daily work for two or three weeks; the rest of the year a rubber curry or slicker once or twice a week keeps it under control. There is no trimming or professional grooming, but the sheer volume of hair from a hundred-pound dog surprises people who chose the breed because the coat was short.
Home environment and care planning
What new owners underestimate is adolescence. These dogs stay mentally young until two or three while carrying ninety pounds, and an excited body check can put an adult on the floor. Teach loose-leash walking and a solid settle while the dog is still light enough to manage.
The bark is deep and carries. Health issues to raise with a breeder include hip and elbow dysplasia, osteochondritis dissecans of the shoulder, gastric dilatation-volvulus, splenic torsion, epilepsy, and urinary incontinence in spayed females. Feed split meals and skip hard exercise around mealtimes.
In hot, humid weather this is a dog that needs air conditioning and early-morning walks rather than an afternoon in the yard.
