Try Grizzly salmon oil. I ordered it from petflow.com. I read tons of great reviews on it. It comes in several sizes, price range varies depending in size. All you need a squirt (pump) per day. Comes in a convenient pump bottle. Although, after reading your other post on his bland diet, I wouldn't add any supplementation just yet. When is good on his food, try the salmon oil. You can also run a site search on coconut oil.
