The first dogs were probably kept at the Hospice between years 1660 and 1670. Undoubtedly, their initial purpose was that of watch dog. Around 1690, Salvatore Rosa painted two dogs from the Hospice. They are described as "Küherhunde" (cowherd's dogs) with slightly heavier heads. The first dog is splash-coated or "patched." The second dog is a "Mantelhund" (dog with a mantle) with primarily, a white head.
The first written reference to dogs at the Hospice, dates from 1703. Prior Balalu mentions that his cook, Vincent Canos, built an exercise wheel to which a dog could be harnessed. When the dog walked, a cooking spit would turn. This invention was not new and considering the number of travelers that had to be fed, it is not surprising that Canos thought of finding kitchen help. The volume of visitors through the Monastery grew such that by 1898, between 18,000 and 20,000 travelers passed through it's entrance, annually. Visitors were afforded three days free lodging with meals, which consisted primarly of meat and bread.
In 1707, a notation in the archives states: "we have lost a dog in an avalanche". In 1731, furs from dogs are mentioned as bed-side rugs. A bill from 1735 shows that the Prior paid for the repair of a dog-collar. In a note from 1787, we read that the Monastery's dogs have successfully warded off a band of brigands. These are the first written documents about dogs at the Hospice. But from where did those dogs come? Certainly, the breed did not have its origin at the Hospice.
The dogs from the Hospice are nearly always described as having exceptional size. But this must be seen as a relative size and probably was considerably smaller than that of modern Saint Bernards. Chroniclers seem to agree that the color of the Hospice dogs was typically red-brown and white. This coloration was wide-spread among farm dogs in Switzerland. Even today, when there are few red farm dogs in Switzerland, we have a saying, used to describe that which is common; "vo dämm git's meh weder rot Hüng" (there's more of that than red dogs). Thus, the red-white coloring was the singular recognizable characteristic of the Saint Bernard. Consequently many red farm dogs, whose ancestors had never seen the Hospice, were sold by enterprising farmers as true Saint Bernard dogs.
Dogs at the Monastery did not achieve great age and on several occasions, the stock vanished completely. In the "Tierbörse" from 1899, a magazine devoted to animal fanciers, we find a hint as to why the monks seemed to have troubles in their kennel. It says that "the dogs from the Great Saint Bernard do not attain the usual age, 6 to 8 years is the maximum... this is a result of the humidity in their quarters, which leads to rheumatism."
