VETS!!!! COULD IT BE DOG MANGE?

It could be demodex or red mange or it could be many other things. Demodex usually does not cause blisters. Most times it does not cause itching. Secondary bacterial and fungal infections are common with this disease. Ringworm is a fungal infection and not a worm Do not use a bunch of home remedies until you know what the problem is. A cleansing bath in a good hypoallergenic shampoo is a good place to start. Don't use medicated baths until you have a diagnosis. Your best bet is to have your dog examined and treated by your veterinarian. Next week is fine as long as she isn't getting worse. Take her anyways even if this seems to be clearing up.
