Prepare a pet first aid kit to bring along on the journey. You'll want to include basic items such as gauze, bandages, first aid tape, an antiseptic, benadryl, aspirin and a sock. A sock pulled over a bandage will work quite well in keeping it in place. As in any outdoor trip where the dog is joining you, you'll want to be prepared in the event an accident occurs. Place all your first aid items in a waterproof container or plastic bag. If you'll be stopping and hiking in the woods, make sure your dog is wearing a flea and tick repellent.
