Izzey had pretty hair on her face but thin hair on her body. I saw an ad for a pet cod liver oil supplement from Nordic Naturals and contacted them. They send me 4 little trail size bottles to try and I could see such a drastic difference when we finished the trail bottles. Her hair thicken up, grew and is shiney. I have also switched all of mine to a grain free natural diet that has salmon and other fish in it so they say she won't need the cod liver oil supplement with that food.
