I’ll check his eyes, I did have my 22 y.o. mares eyes checked last fall due to them looking a little cloudy. My vet thought it could be the start of moon blindness but when I read up on that it really doesn’t look like that to me. She still seems to have a little cloudy on some of her eye and she isn’t spooky at all. Just hard to pin point when there are so many possibilities. But the last spook wasn’t caused my something he saw it was from the small tree swiping under his belly and guessing it poked him somewhere goosing him causing him to lunge and then now its like once he does that lunge and I lose my seat he starts right in with the bucking.
