Harness racing (Trotting) is a form of horse racing in which the horses race at a specific gait (a trot or a pace). They usually pull a two-wheeled cart called a sulky, although in Europe racing under saddle (trot monté in French) is also performed.
Rest place/daily stay
Stables, lately more often in paddocks and pastures
Trotting horses are well trained, hard workers. They spend their days training and racing. Therefore their behaviour towards farriers is mostly gentle. They like the moment of rest that a hoof treatment gives. Their owners are professionals or amateurs on an almost professional level.
Trotting is an unnatural movement, in between walking and a gallop. Therefore the limbs can be overstressed if the balance of the shoeing is not perfect. In that case, the limbs hurt and the horse loses his trot.
Trotting is racing, so trotting shoes are special racing shoes. Because the balance of the shoeing is critical and racing shoes are light and slim, there are many types of shoes in either steel or aluminium. The shape of a trotting shoe is specific, more 'olive' like. Otherwise the steel will be hardenend right into the core and the shoe can break easily.
Communicate well with the trainer. He knows exactely what the horse needs to have a perfect balance.
Trotting shoes are thin shoes. Keep that in mind when buying some tools, like forging tongs.
