Answer
debbie,
I have not heard of this treatment for ringworm.  The only thing I know is lamisil and I don't know if you can use that on dogs.  I would check with a druggist to be sure and call a vet after that.  They will usually answer a phone call.  You need a black light to see if it is a fungus.
