Muzzle skin Issue
I have here a 7 Yo QH, who I have discovered is starting have a bit of Muzzle sunburn. However, there is more when looking further....
What I think here, and I would appreciate all input, looks to me like a type of fungus. It is semi-hard (the lesions in the photo) the are greyish in color, they are bi-lateral, and completely around the nostril area.
This horse is in a not-so-perfect turnout, lots of Lord-knows-what plant life, some overgrowth, and spends to my best guess 10-12 hours a day in turnout.Two other unknown pasture mates...Not sure how long this has been going on. This is all the current info I have.
I am new to this horse, so until further medical intervention can be had, and thoughts?
