i just read that fish oil or evening primrose is good for flaky skin, add one of them to ur dogs foods, its meant to be really good.
then again it could be somethin to do wiv ur dogs diet aswell so look into that. wat are u feeding her on?? maybe some of the others can then tell u wats best for ur dog.
actually raw feeding is best for ur dog, with the natural diet u will deffo see a change in her skin condition and overal appearance.
