In general, I would not recommend planning a trip around the idea of using your dog as a pack mule, but rather as a means of pulling his own weight. It is possible to train some dogs, depending on their size and conformation, to be your beasts of burden, although that is not the subject of this article. A well-conditioned sled dog can carry up to 50 percent of its weight in a pack, but most dogs are neither this strong nor this conditioned. Most dogs, however, should be able to carry a couple of weeks of their own food supply without undue strain. My dogs carry their own food.
Food is easy to pack.
It's uniform and low in density, so even if I fill the packs to capacity, they won't be too heavy. This way, I can travel with the satisfaction that my dogs are pulling their own weight. As their burden lightens, I often replace the weight with some of my own gear dog packs make great easy access compartments. Your main consideration in outfitting your dog will be the purchase of an appropriate dog pack. There are a variety of packs on the market.
