Does anyone have a preference of a supplement or something they add to their pups food for itchy skin? No , my dogs don't have flaky skin, just scratching alot, due to the colder climate. First it was the ears, being reddish, and treated that. Now I hear during the night them scratchy . They are on Purina Pro Plan salmon sensitive skin and stomach. They have been for over a year. They get gr.beans, sometimes cooked eggs in their food, plus a Vit.E . And I've tried Brewers yeast and garlic. Just wondering if something works best for your pups that I'm not aware of yet?
