By the age of three, Haflinger foals are already almost fully grown. However, they may still grow by another three to six centimetres before their fifth birthday. At birth, Haflinger foals are given a name beginning with the same letter as their mother’s or father’s name. Their coats are always sorrel-coloured, while their manes and tails are blonde. Sometimes, they have marks or blazes on their heads; otherwise, they are generally single-coloured. When they are fully grown, they are 138 to 155 cm tall. Although the minimum height for a horse is 148 cm, meaning Haflingers are usually categorised as ponies, they are actually a breed of horses.
