Interesting case history. Could you tell me a little more about the problem.....
1. Any trauma that you know of, specifically, are there any dogs or coyote's that could have attacked the filly?
2. Is the filly more prone to infections than other horses at the farm?
3. Are the area's itchy?
4. Do you notice any other areas that may be starting to form these sores?
5. Any allergies?
Looking forward to your reply.....
After discussing the problem with a friend who suggested I look for the plant "nettle" in my field, I walked the pasture and found the plant suspected. The nettle plant has very tiny thorns that can get into the skin un-noticed. They cause the swelling, hair loss and eventual rupturing. The filly is now on the mend and no other problems seem to exist. Thanks for your input.
