  Hi there. The most common cause of itching and hair loss on the lower back/base of tail area is flea allergies - so if Oreo isn't already on a good-quality flea medication like Nexgard or Bravecto, this is the first thing I would suggest. If you're positive she doesn't have fleas, then other possible causes would include environmental allergies, food allergies, a bacterial or fungal skin infection, or skin mites (mange). Treatment will depend on what the underlying problem is, so I would recommend taking her 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.

  I can't see much from the second picture, but the first picture looks like a hotspot. These can occur from too much moisture, such as excessive licking when the skin itches. The moisture sets up an environment for a bacterial infection, which itches even more, and the cycle continues. The first step is to clip the hair so the skin can dry out - you need to use buzzing clippers, not scissors or a razor. Then bathe the skin to clean it using dog shampoo or a medicated shampoo like Dechra MalAcetic Ultra Shampoo. You can then use a topical like hydrocortisone and neosporin. During the healing time, you will have to prevent all licking, so Oreo will probably need to wear an e-collar or cone. Don't bandage the area because it needs to dry out. If you try this for 48 hours and it doesn't look better, Oreo should be evaluated by a vet. Itching can be caused by fleas, mange, lice, infections (bacterial or yeast), ringworm, allergies, among others. Since even 1 flea bite can make the whole dog itchy, Oreo should be on a monthly flea preventative. Nope, I don't think this is caused by Rabies!!
