What age is a foal fully grown?

Answer 1

This can vary from breed to breed and every horse is different. Some breeds like the Arabian are more slow to mature. But on the average most horses have the majority of their height between the ages of 2 and 3 years old. But they continue to fill out for several more years. When working with young horses you have to be careful not to push them too hard. There is a growth plate in a horse's knees that do not close until after they have acheived their full growth. Like a soft spot on a newborn's head. Too much too soon can ruin the horse's legs. They also need to mature mentally. A young horse has a short attention span. When working with youngsters keep their lessons very short and build up over time. A few minutes a day, twice a day is much better than a 2 hour workout. This is the best time to get a horse's trust that will last his whole life. A horse treated with love and patience will always return the favor when you, the handler, makes a mistake.

Answer 2

They grow. Just like any other animal. They reach complete maturity at age 4. A filly becomes a mare at age 4, and a colt becomes a stallion (unless castrated).
