Hi there and thank you for using pet coach to address your concern. Based on the pictures you have provided, this could be a cancerous tumor that has become infected. This should be examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. It is likely he needs to have surgery to help try and resolve this. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
