I have used Show Stopper and think that it is a very good supplement. Working with rescues and fostering I've often kept underweight (sometimes extremely underweight) dogs. Show Stopper has managed to put weight on them amazingly fast and all of their coats did improve considerably. I know it contains a lot of fats, so I'm assuming that is where the weight gain comes from. With many of the foster kids, I would see results within a week or two.
I think that if I were to use it with an otherwise healthy yorkie, I wouldn't give the full measure it recommends. Using the full measure, I would worry about too much fat in their diet.
