It's definitely not fungal scars or from a cribbing collar. And since some of you brought up that it might be from his sleazy I'm going to take it out to the barn tonight to see if it lines up with the white spots. I was pretty sure it didn't but you may be right since nothing else seems to fit. Thanks for all your help, and any more ideas would be appreciated!
I got pictures of Sunny in his sleazy last night. He was so confused about putting it on when he wasn't getting prepped for a show. Lol
It didn't really cover any of the white spots and when I tried shifting it around it could only have caused about half of them. It has such big eye holes and such small ear holes that it doesn't move around a whole lot. It is pretty snug but I don't think it's too tight on him.
That is his main one but he does have another one. The eye holes are the same size and it fits a bit looser in the face than the green one. That's why I didn't think it could have been his purple one. The green one fits tighter.
