Treating a Dog's Skin InfectionMy Pit/Blue Heeler, Nyla, has had a skin infection for almost 4 months. It is on her neck, vulva, stomach, inner leg, armpits, and under her eyes. I took her to the vet. The medicine never stopped the itching. I tried apple cider, vinegar, peroxide, and water mix. But it seems to be irritating her skin more.
