I am unable to get appt with vets until next week so I am reaching out to see if anyone here could advice on what may be causing this rash and what I could do to help. It seems to be self inflicted as my dog constantly scratches and lickes the area. I also seen the dog bum scooting few times. My dog is cross between poodle and terrier. Regular flea and worming treatment, no recent changes in the diet and taken for walks to regular places.
