I'm housesitting for a freind of mine and I noticed that her yearling's left eye was a little weird looking so when I took a closer I saw that he had some black dots and few red dots in the inside of his eye and there was some nasty gunk in there to. I tried whipping it down but he's real sensative about it. I put his fly mask on but I was just wondering what it might be? I have some pictures that I'll post. There not to good cause he wouldn't sit still. Lol
It's probably a clogged/blocked tear duct. Have a vet check him & they will probably just flush it out. I don't think it's a very expensive procedure but it's not one of those probems that will just go away. Trust me. My old mare had the same problem for over a year before I figured out what the problem was (the reason it took so long is because she was at my aunts which is 3 hours away).
