Today is
Okay so my two big horses both over 16.3.... one TB one QH. The second it warms up have what looks to be dried sweat marks over the back and hips. Doesn't respond to antifungal treatment, EPM treatment, two different vets had no idea.... but my horses are the only ones who look that way. Open pens with shade, free choice alfalfa and mineral blocks? Thoughts? Google is no help
Looks like dried salt to me from the sweat.
Can you rinse it off?
