If you don't want to try to feed it to him, which could prove difficult at any age, try applying the apple cider vinegar to the bottom of the feet with a cotton ball. The vinegar will absorb through the skin and should help calm the stomach. It is also good for diarhea. It dries in about a minute or two. I use this whenever my family gets sick. I have used it for food poisoning, flu, gastric overingulgence. It has worked wonders. Try it and see how it works.
