  • The problem seems to have improved, but you are not sure if the lameness is completely resolved.

You are riding your horse – performance or pleasure – and suddenly your horse stops and will not move forward. You may have heard a sound or felt a bad step. You dismount and your horse is obviously lame on one limb. The horse may not want to walk at all or is limping.

The severity of the injury is likely related to the intensity and type of exercise. For a racehorse, an injury severe enough to overcome adrenaline and speed and bring the horse to a stop may well be catastrophic, a fracture or severe tendon tear.

For a pleasure horse, the injury could be anything from a stone bruise to a tendon strain. Maybe the horse stepped on a nail or other sharp object. Limb to limb contact (interference) may cause instantaneous and severe pain that begins to resolve after the moment of contact.

You may also give the horse a few moments to rest and then ask them to walk them forward. If they are willing to walk forward, the safest thing to do is hand walk your horse to the barn. When you arrive, examine the limb again, especially feeling for digital pulse. With time, swelling may develop giving further clues about the injury.
