My dog has a full body rash. Could it be ringworm? Can I treat it OTC?

Updated on September 23rd, 2025

Pet's info: Dog | Shih Tzu | Female | spayed | 9 years and 7 months old | 18 lbs

Does this look like it could be ringworm and can it be treated over the counter? It’s all over her body

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!
