My dog has a new, severe rash on her private area. What should I do?

Updated On September 23rd, 2025

Pet's info: Dog | American Pit Bull Terrier | Female | spayed | 4 years and 10 months old | 56 lbs

I recently noticed a type of rash on my dogs private area. We took her to the vet 2 weeks ago for her heat rashes, and it got significantly better. But we’ve never seen a rash like this before.

Thanks for using Petco Pet Education Center, formerly Petcoach! This looks like very severe irritation/inflammation. It may be a reaction to something in the environment which may be causing this. Or it could also be something like a severe infection. I would highly recommend you consider going back to your veterinarian if she currently has the rash. They would be able to assess the situation and proceed with therapy accordingly. Best of luck!

    If she’s not spayed she could be coming into heat. That starts with some vaginal swelling. Sometimes dog lick the area and get it irritated. A rash is not usual. You may want to give a cleansing bath to soothe the skin. She may have a rash from grass, pollen or something she has laid on. If it worsens then I’d have the skin checked since it may be a skin infection that needs antibiotics. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Ruby.
