  Hi there. I'm not sure if you meant to attach a photo to your question, but if so, it didn't come through - feel free to try again if you want us to take a look. In general, though, I'm afraid ringworm can't be diagnosed just by looking - it requires testing by your veterinarian. This is not a very common problem in dogs, so in most cases, circular skin lesions are more likely to be due to an allergy or bacterial skin infection, but an exam and testing by your vet would be needed to know for sure. I would recommend taking Mollie in to be seen when you're able to, so that you can find out what she has and get her started on appropriate treatment.
  
  To answer your other question about OTC treatments for ringworm, it really depends on how severe the infection is and where it's located. Sometimes, it can be treated successfully with something like Malaseb shampoo or lime sulfur dip, but in other cases systemic anti-fungal medication is needed, which would be prescription only. But again, I wouldn't assume that Mollie has ringworm unless she's diagnosed by your veterinarian after appropriate testing. It's much more likely that she has a different skin problem like allergies or a bacterial infection.
