Treating a Dog's Staph Infection and Smelly SoresTwo vets told me my Labrador mix has a staph infection. She has been on antibiotics 3 times to no avail. I give her yogurt, grain free dry food, make green bean, carrot, pea, and chicken mix and give her probiotics every day. She is also on thyroid meds. She also has scabby, smelly sores on her back.
