This happens every summer. I always feel so bad for him. We have asked the vet and he said he bobs his head because his brain is receiving little electric shocks. He can't wear a fly mask or it just gets worse and I feel like I'm hurting him while riding. Has anyone ever experienced this? Is there a medicine to fix this? Please HELP ME!
PS: My pony is 16yo and he is about 12.3hh
