It's very possible that your Pet may have a type of mange and/or secondary bacterial infection. You'll want to visit your local Veterinarian and request a skin scraping to rule out the presence of any mite or mange. Be sure to wash your hands before and after touching your pet and wash any bedding in very hot water regularly.

    He could have a bacterial infection or a yeast infection, possibly caused by allergies. You can shampoo him with a medicated dog shampoo and see if that helps but he should be examined by a vet to determine the cause and needed treatment. Once diagnosed, your vet can prescribe medications to help treat. He may need an antibiotic, corticosteroid, or an antifungal. You could also add Free Form Snip Tips to his diet to help keep his coat and skin healthy.
