Unsoundness and other frailties of old age often call for horses to be relieved of day-to-day performance requirements, but regular exercise remains important for older horses. Exercise comes in many forms—it can be as simple as encouraging aged horses to walk from one end of a field to the other for feed and water, or walk-only lessons or lazy strolls.
Exercise boosts health of aged horses in three important ways. First, it encourages a horse’s musculoskeletal health. A sedentary lifestyle weakens bones, muscles, tendons, and ligaments. Aged horses that are stalled at night often seem especially creaky when turned out, and this is likely due to multiple hours of confinement with only occasional movement. Regular, low-impact movement will help keep joints healthy and reduce lameness.
Second, exercise helps keep the horse’s weight in check. Retirement and obesity frequently go hand in hand. An obese horse is not a healthy horse, and for older horses, excessive weight can be a precursor of endocrine problems, including metabolic syndrome. Light, structured exercise can help ward off unnecessary weight and metabolic difficulties. Many horses that were familiar with daily contact will enjoy the interaction, especially if games or new skills are introduced.
Third, exercise can facilitate colic control. Aged horses have an increased risk of gastrointestinal issues, including colic. Specifically, old horses seem prone to impaction colic, likely associated with decreased motility of the gastrointestinal tract. Horses with dental disrepair may also be predisposed to problems rela
