A young horse is called a "foal." This term generally refers to a horse that is less than a year old. Foals are known for their energetic and playful behavior, as they spend their early months exploring their surroundings and strengthening their muscles. A foal can be either a filly (female) or a colt (male), and typically, they are weaned from their mothers around six months, although they may continue to stay close to their dam for social development. The growth and early training stages of foals are critical, as they lay the foundation for their future strength and temperament.
