My dog has dark scabby spots and pimples on his genital area.

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 15 lbs

Dog has dark spots on penile sheath. Looks scabby. Damped cotton pad with peroxide and cleaned it. He isn't acting differently and is peeing normally. I didn't notice these spots until today. There was also a small pustule that looked like a tiny pimple. Help?

The small pinkish pimples are pustules and are suggestive of some more recent infection, the darker ones are the same but slightly older lesions. It looks like a mild skin infection, which can happen quite easily in an rare that can get dirty on walk or when they lie. I would suggest to bathe the area gently with some salty water 2-3 times daily and dry it with a soft cloth or towel afterwards, and see if the pustules disappear and the other ones start to regress, it might take a few days. To make up some salty water, just add one teaspoon of salt per two cups of bolied hot water, then leave it to cool down. Use only when lukewarm, please make sure that you don't burn yourself or Obi while preparing this salty tea ! Hope this helps.
