 The Breed of Horses Act 1535 ("27 Henry VIII, c. 6") mentions a marked decay in the quality of the breed, the cause it is claimed that ""in most places of this Realme little horsis and naggis of small stature and valeu be suffered to depasture and also to covour marys and felys of very small stature"".The statute thus required each owner of enclosed deer-parks to possess a minimum of two mares whose height was to be above thirteen hands high in order for them to be bred with horses of no shorter than fourteen hands high.The Horses Act 1540 ("32 Henry VIII, c.13") ordered that no stallion under 15 hands (60 inches, 152 cm) and no mare under 13 hands (52 inches, 132 cm) was permitted to run out on common land, or to run wild, and no two-year-old colt under 11.2 hands (46 inches, 117 cm) was allowed to run out in any area with mares.
