Saint Bermastiff Breed History

The Saint Bermastiff is a relatively new hybrid, though the two breeds that make the hybrid have long histories. It is believed that the Saint Bernard resulted from crossing dogs that were native to the Alps with Mastiff dogs that were brought by the Roman army during the reign of Emperor Augustus. Establishing the breed was St. Bernard de Menthon and some monks; the dogs were then used by a Switzerland Hospice to help those who were coming through the Alpine pass between the countries of Switzerland and Italy. The breed became a popular choice for rescue work in the 17th Century because they had the ability to smell a person who was buried under a lot of snow in an avalanche. Due to their ability to hear low frequency sounds, the dogs have been found to predict storms and avalanches. The Mastiff is a descendant of the Molosser family and it is believed that he was brought to the British Isles on Phoenician trading vessels sometime between 2000 and 1500 B.C. These dogs were isolated on an island and bred to protect the tribes that lived on the Isles over the course of hundreds of years. During the Roman invasion in 55 BC, Mastiffs participated in the resistance against Rome. Julius Caesar was impressed with the size and courage of the breed and he brought them to Rome to battle lions and gladiators. Over the course of the centuries, the Mastiff continued as a protector and guardian, though also participated in bull and bear baiting and pit fighting. The modern Mastiff is a descendant of these dogs as well as the Lyme Hall Mastiffs. The foundation of the Lime Hall Mastiffs and future English Mastiffs was the dog of Sir Peers Legh, who was fatally wounded in a battle on October 23, 1415 in northern France. His Mastiff defended him for hours during the battle and returned home with a litter of puppies. The Mastiff ultimately was selectively bred to minimize the qualities that caused concern, creating a large docile dog that earned recognition by the American Kennel Club in 1885.

Saint Bermastiff Breed Appearance

The Saint Bermastiff will inherit traits from both of his parent breeds; as with all mixed breeds, you can anticipate that he may inherit more physical characteristics from one or the other parent breeds, or a relatively equal combination of traits from each breed. Typically, the Saint Bermastiff will be large with a short to medium length coat that is soft and fluffy and often, there is feathering on the legs. The head of the Saint Bermastiff will be wide and include a square face, large ears and a short muzzle. His lips and nose will be black. The tail of the hybrid will frequently be thick and wide close to the body, tapering throughout the length. The body of the Saint Bermastiff will appear short and thick with a broad, deep chest. His eyes are dark and round and have an expression of kindness and understanding.

Saint Bermastiff Breed Maintenance

Maintenance of your Saint Bermastiff will depend upon the coat that he inherits. Should he inherit the smooth or rough coat of the Saint Bernard, grooming will be relatively easy. Brushing his coat with a firm bristle brush on a weekly basis will help with shedding and he should be bathed as needed with a mild soap developed for dogs. If the hybrid inherits the short-haired coat of the Mastiff, he will require weekly brushing and the removal of dead, loose hair, particularly during his two shedding seasons. The hybrid may inherit the increased oil produced by the Mastiff which can lead to an odor and require regular bathing; though you will want to be careful to be sure that you don’t strip away the necessary oils. Regular brushing will help keep the oils evenly distributed. Regular ear cleaning is helpful to avoid infection and as with all dogs, his teeth should be brushed every one to two weeks to ensure his long term dental health. As the hybrid can be prone to bloat, it is best to feed him two to three times per day as opposed to giving him one large meal.

Saint Bermastiff Temperament

The Saint Bermastiff will inherit his behavioral traits from his parent breeds, the Saint Bernard and the Mastiff. The hybrid will be easygoing and loving, with a desire to please his humans. The Saint Bermastiff should not bark much and will have times where he prefers to be lazy. Both parent breeds are loyal to their humans and this can be expected in the hybrid as well. The Saint Bernard and the Mastiff are gentle dogs despite their large size and both are protective toward their humans; this will likely be the case in their offspring. As both breeds display patience and are good with children, the hybrid should be as well. It is recommended that because of their size, interactions with smaller children be supervised; neither parent breed is aggressive, though as a result of their size they could inadvertently harm someone small. While the hybrid will be loving with his family he will be leery of strangers and will likely require socialization from a young age in order to interact well with other animals.

Saint Bermastiff Activity Requirements

The activity requirements of the Saint Bermastiff will vary by the particular dog and the traits that he inherits from his parents. The Saint Bermastiff is often active, requiring regular exercise. A dog of the hybrid is able to live in an apartment as long as he is taken for short walks on a daily basis or has access to a small yard where he can be active. The Saint Bermastiff will do well in cold temperatures, though will likely struggle in particularly warm weather. When it is hot outside, it is important that you offer your Saint Bermastiff plenty of water and ensure that he has access to shade.
