The sleeping habit of horses is far different from other animals, including humans. Horses usually rest in a standing position, weight put on the front and hind legs, the other leg will relax. According to Dr. Joe Bertone – Horse Medical Professor at Western Veterinary University (USA) – horses will only lie down when they feel safe. However, this time is very short because the body weight is too large will put pressure on the horse’s internal organs when lying.
Scientists at the University of Arkansas (USA) said that although not 100% accurate, but by examining the teeth, it is possible to estimate the approximate age of a horse without knowing the date of birth. Horses are born usually have 4 incisors (2 upper jaw, 2 lower jaw). If not, after 8 days they will grow. Eight weeks later, horses begin to grow molars and by about 8 months of age, they grow enough milk teeth. Later, the milk teeth gradually shed and by about 2.5 years old, they will grow permanent incisors. 5 years old, the horse will have enough permanent teeth.
