Horses reproduce by the male impregnating the female resulting in a live, single birth; the female, or mare, carries the foal for approximately 11 months. Foals are usually born in the spring with the ability to walk, stand and run.
Foals can focus their eyes, stand, nurse and run within an hour after their birth. Their legs at birth are almost as long as they will be when fully grown. They are born without teeth. They get milk teeth within the first 6 months and adult teeth by the time they are 6 years old. A horse’s age is determined by their teeth.
