It looks like your dog has a skin infection so he should be examined and treated by a vet. He, likely, needs an oral antibiotic and an anti-inflammatory that your vet can prescribe. If the meantime, you can bathe him with a medicated shampoo, like Douxo Chlorhexidine. You could also spray the lesion with Vetericyn wound and skin care spray.

It could be a bacterial skin infection. You could continue to apply the antibiotic ointment but if it does not resolve than he should be examined by a vet to determine the cause and treat the problem. He may need an oral antibiotic and corticosteroid to help treat.

It looks like he has a hot spot. You could continue to clean the area with something like DOUXO® Chlorhexidine Pads and see if it completely resolves. Otherwise, he will need to be examined by a vet for treatment. He may need an antibiotic and corticosteroid to treat the problem.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. This could certainly be a skin mite infection but without examining it or seeing a picture, it is difficult to say for sure what it could be. I would recommend having a veterinarian take a look at this so that the most appropriate diagnostic and treatment recommendations can be made. I would recommend that a skin scrape be performed on the lesion to rule out skin parasites. It may be a bacterial / fungal skin infection as well. If you are unable to get to a vet right away, I would recommend using a product called Malacetic conditioning spray and apply 2-3 times per day to the lesion until resolved. You can find this spray online quite easily. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
