My dog has a blank spot. We think it has always been there, but it seems to have gotten bigger. We wonder if it may be ringworm?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Judging from the photo, it does not appear to be ringworm to me. This could be a skin parasite such as Demodex or a skin infection. I would recommend having Angel seen by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. 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.
