Saint Bernards are among the largest dog breeds. Adult males typically weigh between 130-180 pounds, while females usually range from 110-150 pounds. Their height generally measures around 26-30 inches at the shoulder, with males being slightly taller than females.

Saint Bernards are known for their gentle, friendly, and affectionate temperament. They are typically very good with children and are known for their calm demeanor. Despite their large size, they are usually sweet-natured and friendly with other pets and people. Their intelligence and willingness to please make them relatively easy to train, although early socialization and consistent training are important to ensure good behavior.

The coat of the Saint Bernard can be either short-haired or long-haired, both of which are dense and weather-resistant. The short-haired variety has a smooth coat, while the long-haired variety has a wavy, flowing coat. Saint Bernards traditionally come in colors such as white and red, brindle, and combinations, with distinct markings. Regular grooming is necessary to manage shedding, especially during seasonal changes, with brushing recommended several times a week.

This breed thrives in environments where they receive plenty of companionship and moderate exercise. Saint Bernards can adapt to various living situations but are best suited for homes with ample space. They enjoy being part of family activities and should not be left alone for extended periods, as they appreciate social interaction.

Saint Bernards enjoy a variety of activities that keep them physically and mentally stimulated. Daily walks, playtime, and gentle exercise are essential for their health. While they are not as energetic as some other breeds, they still enjoy outdoor activities that allow them to explore their environment. They can also participate in therapy work, obedience training, and gentle canine sports suited to their temperament and abilities.
