seems so many of our Pitties have 'skin' issues.
when i first got my girl she had a lot of problems..itchy.hot spots.loose stools, etc.
i put her on the same food my dobes get.purina pro plan salmon and rice and she has had no skin or digestive problems since.
ACV is a very good supplement to feed your pets too. you must start out with just a few drops added to their water or food and slowly build it up to a tsp. or two a day, depending on the size of your pet.
To help soothe irritated skin........an oatmeal bath works wonders.
