Not as such. We have a husky and a leonberger. Both lovely dogs who love the snow. We are training the husky, Khumbu, to pull us uphill on skis. Last years training was pretty good and we managed to do this. His attention span is short however and if he sees a mountain goat he tends to charge off in chase, dragging the hapless skier behind in his wake!!!!
They would come out on normal winter excursions should our clients like the company of dogs.
