I have a 14 week old pup with tiny skin flakes and very small dandruff like patches on his chest. They don't seem at all itchy. I've researched scabies, can't get a good photo or information on that. There is no hair loss, we see the little flakes and feel tiny bumps, they really can't be seen very well. We've kept several others from the litter, none of the others have it. Any ideas, suggestions?
