You certainly CAN take your dog on your hike! IF you are prepared to get him properly ready. He most certainly CAN carry at least some of his own gear and food, but he must be conditioned to the weight. As for the cold, I would look into having a customade fleece suit made for him and a properly designed sleeping bag. If you condition him to hiking in cold he probably won’t need the suit while he is moving, but he may when you stop to rest and for the night. The bigger problem is HEAT. Dogs do not disapate heat well at all and when it is humid they have even more trouble. Be SURE you are prepared to treat him for heat exhaustion and that you CAN carry him out if you need to. Learn the proper treatment for heat troubles and make sure that at ANY time on the trail you can initiate those procedures. Be SURE that between you he and you can carry a safe amount of water.
Sled-dog sites probably aren’t going to help much, since sled-dogs have the coats and the training to cope with very cold conditions. But they DO have very nice “booties” to protect dogs feet and I would strongly suggest getting a set or two for when hiking conditions are very rough or very hard and dry.
Make SURE your dog is well trained in obedience! It is absolutely essential that they have a good, solid recall and down-stay. Those are the bare minimum. Dals can be difficult to train, but it is necessary. It is good, too, if your dog will bark on command - could be useful if you get hurt, but he must also SHUT UP on command and stay quiet!
Dals are endurance dogs, their original use as a working dog was to follow coaches for miles and miles and to act as guard dogs. Long distance hiking should not be a problem for a properly trained and conditioned Dal. It’s true they aren’t draft animals, but they can still carry at least some of their equipment.
