Thanks for reaching out about Wilbur and including a photo. At first appearance, two possibilities come to mind: ringworm (fungal dermatitis) and a benign tumor called a trichofolliculuma. A veterinary visit is recommended for both situations to provide a diagnostic/treatment plan. Ringworm will require anti-fungal treatments, and is possibly contagious to people. The trichofolliculuma would need minor surgery to remove. Good luck.
