The lesions that you are seeing on the back of Bruce's neck could be a result of a skin infection from his excessive scratching (possibly related to allergies to fleas, food or environmental factors), but could also be associated with ringworm, mange or benign or malignant cancerous processes. Bruce should go to his vet for evaluation because he likely needs a course of antibiotics to treat any infection present. Until you can get to the vet, keep an e-collar (cone) on him to prevent further scratching and skin damage. Also be sure that he is receiving a high quality flea preventative (such as Nexgard, Bravecto or K9 Advantix II) regularly. Baths in an antibacterial shampoo (here is one example: http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=27982) may be beneficial until his vet appointment. I hope that all goes well!
