What activity are the people enjoying with their dog in the snowy weather?

In the snowy weather shown in the image, the three people are enjoying cross-country skiing while being pulled by a large dog on a leash. The combination of skiing and having the dog pull them adds an extra element of fun and excitement to their activity. It is a unique way to bond and exercise together with their pet, taking advantage of the snowy conditions for an engaging outdoor activity.
