Hi there and thank you for using pet coach to address your concern. Judging from the picture, the bump you are referring to appears to be what we call a sebaceous adenoma. These are typically benign wart like skin tumors that develop in older dogs. Sometimes these can open and bleed when they get caught on something. I typically recommend removing them when they start to become bothersome or bleed. Otherwise, you can monitor the bump for now. I hooe this helps guide you in the right direction. Please let me know if you have any other questions or concerns.

    It looks like these may be sebaceous adenomas or papillomas (warts). With either of these causes, often more will pop up. They don't usually cause any issues, but they can become damages easily, especially after grooming, which causes them to bleed a little and itch a lot. I would recommend that you have them examined by a vet for diagnosis.
