Keegan is only 4 mos old, but I noticed that when I would pet her down her back she had horrible flaking and dandruff. I asked the vet about it and he said that it was probably the change in weather. But it didn't get any better so I started adding 2 Vit E capsules to her food (she gets fed twice a day) and a tablespoon of vegetable oil. I only added the oil once a day, maybe every other day. Her coat has become softer and shinier and the flakes are almost completely gone. I did this with Shaianne also when she had the same condition. I also add 1 T of plain nonfat yogurt which also helps too, but I add it b/c even tho she is little she has killer gas. I don't know why but she totally does!! Makes my eyes water!
