You will need to take your dog to a veterinarian for a skin exam. Your dog could be suffering from an allergy, mites, fleas, a bacterial or fungal infection. Each of these requires a different treatment, so it is important to find out what is causing the the rash. Your vet will do a thorough exam and maybe a skin scrape. He will then discuss the options with you and then prescribe medications, possibly give an injection to stop the itching, if your dog is itching.

    I don't think either of those will help much, but they won't hurt, just make sure that your dog doesn't lick it off. This rash looks evident of chronic inflammation, which could be caused by atopy, flea allergies, food allergies, chronic yeast or bacterial infection, mites, etc. I would recommend that you have your dog examined by a vet so that the actual cause of the rash can be diagnosed and treated to prevent flare-ups on the skin.

    If it does not seem to bothering him that much you can try using this antimicrobial spray (link below) on the rash for a week or so. If after treating it, it does not look better then you should take him to your vet for an exam. ( https://www.petco.com/shop/en/petcostore/product/vetericyn-plus-wound-and-skin-care-for-dogs )
