Yep, all depends on the abscess. Anything that opens out along the coronary band needs to be kept open. If you have a large defect in the sole that was created, you need to keep it protected until the body can seal the area off, at least 5-7 days usually. Sometimes these areas will act like a 1-way valve, where as debris packs into it, the more the horse moves around, the more that pack in and under the sole. But either-way, ask your veterinarians opinion and have him explain the reasoning, as treatment will vary depending on the abscess.
