I would give him two or three of the capsules a day. A little extra is not going to hurt him. After you see some results, two would probably be fine. The vitamins that are in dog food are usually not very effective because they get sprayed on. Omega 3 is very delicate and doesn't have a high heat tolerance or long shelf life. It is best to add your own. Also Omega6 is not the same thing. Chicken is high in omega 6 but I'm not sure if that is very stable in kibble either. If you want to add both, you can give Missing Link. That stuff is really good.
