Horse HeightHorse sizes vary a lot by breed but a horse is over 14.2 hands when measured at the withers. The average varies from breed to breed, as obviously a light show hack who's maximum height is around 16.hh is never going to have the same average height as a shire or other draught/heavy horse who's minimum height may be 16.hh.
They have seven. A horse has 7 cervical vertebrae (neck) as do nearly all mammals, 18 thoracic vertebrae (along the longest part of the horse's back), 6 lumbar vertebrae (the general area above the horse's hips), and 5 sacral vertebrae (towards the tail (dock) area).
Horses have 7 cervical vertebrae. In fact, most mammals have 7 cervical vertebrae, even giraffes, the bigger the animal the bigger the vertebrae. There are a few exceptions: Sloths have 8 or 9 cervical vertebrae while manatees have only six!
