Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on the picture you have provided, it appears that this could be bacterial or a skin parasite causing the lesion. The skin may need to be cultured and if a skin scraping has not been performed, I would certainly recommend having this done to make sure this is not due to a skin mite such as demodex. If this is not due to a mite and is still there, I would recommend a culture / biopsy of the area for a more definitive diagnosis. 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.
