My TB mare has a fungus on her hind leg (the only one with a sock) that only covers the pink skin. The fungus creates huge, hard scabs that are difficult to remove. I wash her leg frequently/daily and have tried multiple shampoos. Right now I am trying a sweat with Hydrocortisone cream, Triple Antibiotic ointment and antifungal cream. It gets the scabs soft enough to where I can remove them. The issue is when the leg is clear, keeping it clear. I also keep her sock clipped.
This has been an ongoing problem with her for about a year, on and off. I have had multiple vets look at her and give their remedies (some Rx, ointments, creams, antibiotics, etc...). Some help for a while but then the scratches (that's what I am calling them) come back. Any advise?
She doesn't wear boots, is turned out 24/7 so dew could be a problem, is on multiple supplements including an immune booster.
