Fly season is back in full swing. As any of you who own horses know the flies are back with a vengeance. This is the time when we begin to see habronema or “summer sores” pop up on horses. These nasty sores are often times difficult to treat, and must be treated every day or they will not heal. If you see a non-healing wound on your horse that just seems to fester or gets worse, chances are you are dealing with a summer sore. The longer you wait to get it treated the harder it will be to get it under control. They seem to appear out of nowhere and get bad very quickly. Common areas that we see summer sores are: on the corners of the mouth, the front of the fetlocks, in the corner of the eyes, on the sheath, or on the end of the urethra.
