This sounds like Bruce has a skin infection, or pyoderma. This usually needs antibiotics to resolve. However, in the meantime you can bathe him in an antimicrobial shampoo such as chlorhexidine or salicylic acid. These can be found in the human shampoo aisle in the dandruff area. Best of luck and thank you for using Pet Coach.
