Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on the picture, I suspect that this is a pustule that ruptured and crusted over. This could be due to a localized skin infection or this could be a fungal infection such as ringworm. The vomiting is likely unrelated so I would not worry about that as long as he is improved. For the skin, I would recommend having a veterinarian examine the area so that the most appropriate diagnostic and treatment recommendations can be made. A topical and / or oral medication may be needed for treatment. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
