Owners and trainers love their horses and have invested huge amounts of time and care into looking after and training them. The last thing they want is to have to put down a horse. But horses have far more complex physiology than humans, and a broken leg can often cause damage to blood vessels and other tissue. Because horses can not stay off their feet for long periods, broken bones do not have a chance to heal, and so often sadly the kindest way to help a horse with a broken limb is to put it down.

The vets on the racecourse, in conjunction with the owner, will make a decision as to what is in the best interests of the horse. Racehorses enjoy a very high standard of care and quality of life when in training. Maintaining a comparable quality of life is a key consideration when considering future options for a horse that has had a serious injury or condition.
