Thanks for using Petco Pet Education Center, formerly Petcoach! This looks like a focal infection though an examination is needed to know. 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. It may be the picture but I am concerned that there may be also a lump as well. If that is the case, that should be evaluated to know if it is actually a growth. Good luck and have a good night!

    Thanks for using Petco Pet Education Center, formerly Petcoach! This looks like a focal infection. You can try to use a chlorhexidine containing shampoo to bathe her twice weekly for a week. You may find these online or at your local pet store.
