Poor pup! There are a number of different things that can cause redness, hair loss, and raw spots like this. Some common possibilities would include allergies (food allergies, or an allergy to something in the environment), a bacterial or fungal skin infection, or skin mites (mange). Treatment will depend on the underlying cause, so it's important to get a diagnosis first in order to know what she needs. Because of this, I would recommend taking Pepper to the vet for an exam. He/she can do some simple skin tests if needed to help diagnose the problem and get her started on appropriate medication to treat it.
