St. Bernard
Discover the St. Bernard's history from Alpine rescuer to giant companion, covering their health risks, temperament, and the truth about the brandy barrel myth.
9.3 years average life expectancy, significantly lower than the 12.7 years typical for other purebreds. This shorter lifespan is driven by a high prevalence of specific genetic conditions, including bone cancer, heart disease, and joint dysplasia.
The St. Bernard is a giant molosser breed originating from the Western Alps, specifically bred for rescue work by the hospice of the Great St Bernard Pass on the Italian-Swiss border. While they are famous for their gentle temperament and massive size, the breed has undergone significant changes over the last two centuries, evolving from a working dog the size of a German Shepherd to the show dog of today.
From Alpine Rescuer to Show Dog
The breed's history begins at the Great St Bernard Hospice, where monks acquired their first dogs between 1660 and 1670. The earliest written records date to 1707, though paintings by Salvator Rosa from 1690 provide visual evidence of the dogs' presence. The most famous of these was Barry, who reportedly saved between 40 and 100 lives before his death, earning a monument in the Cimetière des Chiens and a preserved body in the Natural History Museum in Bern.
The modern St. Bernard is radically different from the original dogs kept at the hospice. Severe winters between 1816 and 1818 killed many of the original dogs during rescue missions. To preserve the breed, the remaining dogs were crossed with Newfoundlands and other large breeds in the 1850s. This crossbreeding introduced a long coat that was ill-suited for the snowy climate, as the fur would freeze and weigh the dogs down, reducing their effectiveness. Consequently, the breed grew much larger and heavier, prioritizing appearance over working ability as kennel clubs and dog shows gained prominence.
Physical Traits and Appearance
Today, the St. Bernard is recognized as a giant dog with a smooth coat that lies close and flat. The coat color is primarily white with red patches, ranging from a clear to dark red mantle. The most valuable coloration is described as reddish-brown, though brindle reddish and brownish-yellow are also allowed. The tail is long and heavy, held high, and the eyes range from light to dark brown with naturally tight lids.
Unlike the original working dogs, the modern St. Bernard is much larger and more massive. The breed has been refined since the late 1800s using various large molosser-type breeds, including the English Mastiff, Great Dane, and Greater Swiss Mountain Dog. The Swiss St. Bernard Club was founded in Basel in 1884, and the breed became the first to be entered into the Swiss Stud Book that same year, with the breed standard approved in 1888.
Health Risks and Longevity
The breed faces several serious health challenges that contribute to their reduced lifespan. A 2024 UK study found the average life expectancy to be 9.3 years, compared to 12.7 for other purebreds. A 2005 Swedish study indicated that 74% of St. Bernards died by age 10, a rate much higher than the 35% for the general dog population.
Specific genetic predispositions include osteosarcoma (bone cancer), which is hereditary, and a mutation in the ARHGEF10 gene associated with a juvenile-onset polyneuropathy. The breed is also highly prone to dilated cardiomyopathy (DCM), with an American study finding 2.6% of St. Bernards affected compared to 0.2% of mixed breeds. Joint issues are common, with the breed being the second most predisposed to hip dysplasia at 14.70% and having a high prevalence of cruciate ligament deficiency. Additionally, gastric dilatation volvulus (GDV) is a significant threat, with an odds-ratio of 4.2 for the breed compared to others.
Temperament and Working Ability
Known as a classic gentle giant, the St. Bernard is calm, patient, and sweet, particularly with children. They are loyal, affectionate, and generally not instinctively protective, though their size alone serves as a deterrent to intruders. While they are no longer used for Alpine rescues, with the last recorded instance in 1955, they retain their natural ability for scent work and can participate in tracking or search and rescue events with proper training.
The dogs at the hospice never received formal training from the monks. Instead, younger dogs learned search and rescue operations by observing older dogs. This method of learning allowed the breed to develop a strong bond with their human companions and a natural aptitude for finding lost travelers.
The Brandy Barrel Myth
Popular culture often depicts St. Bernards carrying small barrels of brandy around their necks to revive avalanche victims. This image is largely a myth originating from an 1820 painting by Edwin Landseer, Alpine Mastiffs Reanimating a Distressed Traveller. The monks of the hospice deny that the dogs ever carried casks for medical purposes, noting that the brandy would have been medically unsound for hypothermic victims. While the monks did keep casks for tourist photographs, the idea of the dog as a walking liquor cabinet is a fictional exaggeration.
