Greater Swiss Mountain Dog

Confident, loyal, and easygoing, the Greater Swiss Mountain Dog was bred to work alongside people, and that partnership instinct shows in how attached they get to their families. They're friendly and patient with kids and generally good with other pets, though their size means supervision matters with small children or tiny dogs.

Moderate energy for their size, a couple of brisk walks or a good romp in the yard each day keeps them content. They enjoy having a job (pulling, hiking, weight-pulling sports) but aren't a breed that needs hours of hard running.

The dense double coat sheds steadily and heavily during seasonal blowouts, so plan on brushing a couple times a week (daily when it's really coming out). Otherwise upkeep is straightforward, occasional baths and regular nail, ear, and teeth care.

Smart and eager to please, they respond well to calm, consistent, reward-based training. Early socialization and basic manners are important simply because of their size and strength, a well-mannered 130-pound dog is a joy, an untrained one is a handful.

Like many large breeds, they're prone to hip and elbow dysplasia, and their deep chest puts them at risk for bloat, so knowing the signs and avoiding vigorous exercise right after meals helps. Keeping them at a healthy weight takes pressure off joints and is one of the best things an owner can do for a long, comfortable life.

This is a big dog with big-dog needs, space, sturdy furniture, and a vehicle that can fit them are worth thinking about before bringing one home. They mature slowly, often staying puppyish in mind well after they've reached full adult size.
