Alaskan Malamutes are naturally agile dogs and they'll love the opportunity to dart, dip, dive, duck, and dash around an obstacle course of a reliable make.

This activity will give your dog quite a workout; weight pulling involves strapping your dog to sled with a certain amount of weight piled on top of it and then encouraging them to pull it for a set distance. It can be a lot fun for your dog and a great way for them to get into better shape for any future Dog Sledding sessions.
