My horse has had scratches for 2 years, even with vet intervention. I bought him with them, and I have gotten them down to these 3 ‘scabs’ that I can’t seem to get rid of. Though I’ve had amazing luck with Fungasol Cream. Smear it on, let it sit overnight, reapply it next day (without washing the leg), then on the 2nd day I wash the leg and the scratches scabs come off easier. I put normal Tri-Care Wound Treatment on the sensitive scabless skin. You have to be super consistent with it to make sure the scabs don’t come back, I’ve never been able to get 100% fully rid of them. But I went from legs covered in them, to just a few. Hope this helped! Good luck!
