Does anyone have any tips for handling summer sores. This is the second year in a row my horse has a bad one. Last year it was on the bulb of his heel, and it took almost 6 months to completely heal. Now he has one on the bottom of his cheek bone. We are keeping it wrapped (which is fun with a face wound) and keeping flies off it, and giving ivermectin every 10 days (all per the vet). Any other tips?
If you are lucky enough to live where summer sores are not an issue, they are wounds that start out just as regular little nicks or cuts, then flies lay eggs into them and the larvae is what causes the wound to worsen. The normal treatment is to give them ivermectin every week to 10 days to kill the larvae and keep it wrapped to keep flies off it. There is only a certain type of fly that causes it, and I think the fact that my barn used to be a dairy barn has something to do with it. We are moving him next week so hopefully that will help. I don't have a photo of my horse's wound, but here is one I found on google images:
