Thanks for using Petco Pet Education Center, formerly Petcoach! This looks like a skin infection. Although in theory possible, ringworm seems unlikely. You can try to use a medicated shampoo containing chlorhexidine twice weekly for 2 weeks. If there is no improvement or in the meantime this appears to be getting worse, have her evaluated by a veterinarian for further assessment and treatment. Good luck and have a good day!
