hi Bunny - my vet did not "like" the idea of Program either. It turns out that his vet school at the Ohio State University, is where I actually found positive references to using this medication as a promising flea treatment. Anyway, that is what finally got rid of ringworm here. I quit the scrubbing, bathing and $100 prescription. I still was a bit of a clean freak and handwasher - but I believe it was the Program that took care of the ringworm. I gave Emily two largest dog tablets (one initially and a repeat the next month) I gave one dose to the remaining kitties as prevention. My cats gobbled up the tablets like a treat, too I bet this does the trick, Bunny. Good luck!
