This isn't too much to ask from a forum, but it IS too much to ask from your dog. Some dogs are more light on their feet than others. No training can effectively make your dog silent in the forest yet move comfortably and naturally. General training, like teaching your dog to stay, move forward little by little, or be focused on you, can help with situations that require stealth. Though if you are hiding from a killer, I am afraid your dog would be the least of your worries.
