An omega-3 (or fish oil) capsule once a day is good for both skin and overall health. I put it in a dab of pumpkin and heat it in the microwave, then mix in a little warm water and use it to moisten dry food for Ava's morning meal. A quarter- or half-teaspoon of olive oil mixed in with food will help dry skin, too. (If it causes diarrhea, step down the amount.) Some people mix the olive oil with warm water and massage it onto the skin, but I've stuck with the internal treatment and that keeps the coat soft and glossy. This winter has been brutal!
