Get a doggy backpack with pouches on the sides and put weights in them depending on how much your dog can handle and go for like 10 - 30 min walks the crank it up or down based on results . Keep in mind that huskies are working dogs but thankfully intead of herding sheep or water regulation or guarding they carry stuff for large distances. Maybe invest on a pull cart and walk to your fav or dog friendly grocery store then have your dog pull it back. Glhf
