The primary concern is the one "weeping." Friend who has been in horses for about 30 years said, "Looks like allergies." It's not causing him pain, but I'm curious about what it could be. Someone also pointed at 'clover blisters.'
Any ideas on the forum? (Most importantly, anyone seen this before?) Will be making a point to talk to my vet when she comes out for the Spring rounds to be on the safer side of things. None of our other horses have them. (Pictured before cleaning.)
