Open Question: We were told our dog has staph but we’re not sure?

Our Jack Russell was scratching severely the last couple of years. The vet gave her allergies shots, steroids, and antihistamine. She then developed black spots on her belly that we first thought was dirt. The vet told us she has Staph infection. Shots weren't helping, so we put her on raw food. It helped her scratching a bit, but not much. We've tried specialty skin shampoo's and fish oil. We thought maybe its a reaction to too much yeast, so we took her off anything that would have flour. Still to no avail, the spots are spreading and her hair is coming out. She doesn't have patches of hair missing, just thinner hair all over. Any ideas? Has anyone been through this?
