Hello all !!! I have my little guy on the breeders recommended royal canin for yorkies puppy food. Within the last 3 weeks, he has developed dry flaky skin. the breeder recommended I use Olive Oil shine spray on his coat after his bath and Olive Oil shampoo and conditioner. I have followed this advice to the letter but after bathing he has "dry skin flakes" that look like dandruff. Anyone else experience this ? what can I do ?
