From what we are told in the passage, we can assume that.....

Beginning in about 1750, the massive sad-eyed
dogs known as Saint Bernards were bred for
mountain rescue work by the monks of the St
Bernard Hospice on the Italian-Swiss border.
Barry was the most successful of all their dogs
because he seemed to possess an extraordinary
ability to sense an oncoming avalanche and to
locate travellers trapped in the snow. After
Barry died, the monks continued to name each
of their chief dogs in his honour. The original
Barry can still be seen, stuffed, at the National
Museum in Bern, Switzerland. In 1961, a car
tunnel was constructed beneath the St Bernard
Pass and the need for winter rescue work
became a thing of the past. The monks at the
Hospice continue to breed the dogs, however,
but now export them as pets.
