Horse breeds are distinct groups of horses that share specific characteristics, such as size, color, and temperament. Each breed has unique traits that make them suitable for various activities, including riding, racing, and work. Popular breeds include the Thoroughbred, known for its speed, and the Clydesdale, recognized for its strength and size. Breeds are often categorized into three main types: light horses, draft horses, and ponies. Light horses are typically agile and fast, making them ideal for riding and racing. Draft horses are larger and stronger, used for heavy work, while ponies are smaller and often favored for children and beginners.
