Polo ponies are specially trained horses used in the sport of polo. They are typically between 14.2 and 16 hands tall and are known for their agility, speed, and endurance. These ponies are often a mix of breeds, including Thoroughbreds and Quarter Horses, which helps them excel in the fast-paced game. In polo, players ride these ponies to hit a ball with a mallet while trying to score goals. Each player usually has several ponies to rotate during a match, as the game can be physically demanding for the animals. Proper care and training are essential to keep polo ponies healthy and competitive.
