It is super important to make sure those growth plates are closed before starting horses. Growth plates at the knees and hocks typically close at 2-3 years old. It is usually safe to start riding horses at this age as long as the growth plates have closed. It’s also important to keep in mind that the equine skeleton is not fully developed until the age of 6 and horses undergo a lot of changes in their body up until then. Riding horses before the age of 2 or before growth plates close can have serious damaging effects on their long term soundness. Studies have shown that bone adapts to stress in small amounts causing the bone to strengthen. While light exercise and stress can help the bone to remodel stronger, too much can have adverse effects on development and especially on joints. Horses skeletally mature from the bottom up— the third phalanx (coffin bone) is the first to mature and the back is last to mature. Starting horses is exciting, but it is important to make sure your horse is physically ready before doing so.
