Lesions in the picture have several potential causes including mange, a skin infection or allergies. Bathing Mojah may be helpful; however, if the lesions are caused by mange or a skin infection he will likely need additional treatment. If the lesions are not improving, are becoming worse or if Mojah is not feeling well, he should be seen by a veterinarian. They may perform a skin scraping and or cytology of the skin to get a better idea of what is causing the lesions.
