, or DSLD, is a degenerative genetic condition that causes the horses suspensory ligaments to become inflamed and gradually break down, leading to the stretching of the ligament. The condition was renamed Equine Systemic Proteoglycan Accumulation (ESPA). Without access to fresh air and pasture, horses tend to develop other health problems that may require more care and additional medications. Riding a horse with a diagnosis of DSLD is not recommended. This stops it from hyperextending during motion. Please keep in mind that we may receive commissions when you click our links and make purchases.
