I have a 9 week old pup who seems to have really bad dandruff. I also just noticed on one of his elbows he has this yellow dry skin stuff???? And I dont know whether to wash it, scrub it, leave it alone??? I have been reading online and found so much information, but some say not to bathe your gsd all the time because they have sensitive skin and others say to get special shampoos and bathe often to help their skin... So I'm not sure what to do. We just got Zeus on July 4th and he has been to the Vet but we just noticed this dry skin. He has also been itching and when he does you can see the dandruff. I did use an Oatmeal shampoo on him but his coat still feels rough and his skin still feels dry. Any suggestions on special shampoos or supplements I should give him?
