It happens, I think everyone at some point has to deal with ringworm. We have a case of it here. We suspect we picked it up from the dogs -- not sure where the dogs picked it up from -- but it happens.
We were using over the counter meds for it, and thought we had it all cleared up. Several week went by with no skin rash or signs of ringworm. However, we really didn't get rid of it. Noticed yesterday a spot had return in the same exact location. So we scheduled an appointment with the doctor. Looked at it and said yep ringworm and because you attempted to cure it with over the counter meds and were not successful we will give you a script for it.
Now to check the dogs again for active ringworm spots and then decided if I should go to the vet and get meds for them too or just treat it with something over the counter like coconut oil. I wouldn't just treat your dogs with coconut oil for this or anything else without reading many reliable sources on the matter.
