I always have questions, but recently wondered about fly masks. Our gelding has eyes that tear up a lot and the flies love that, even with bug spray. We bought him a fly mask and he seems fine with it, but when I check him later in the day, there is hay sticking in the eye area and that can't be comfortable either. First question...mask? best kind? Second question...best bug spray?I do have an appointment with the vet for September 11 to see if the tear ducts need to be checked.
