A field hunter, or a fox hunter, is a type of horse used in the hunt field for foxhunting. It may be of any breed, but should possess stamina, a level head, and bravery. The horse should have a safe jump, so as not to get caught on any of the solid obstacles found in the hunt field. The type of terrain is also an important factor: wide open, flat land is generally best for horses of a Thoroughbred type, while rockier, more unforgiving land may be best suited by a draft-cross or tougher breed. Some of the best field hunters are from Ireland, most notably the Irish Horse.
Field hunter trials are regularly held to test these horses, and have become a popular form of equestrian competition. Often the horses are judged over several days of fox hunting, with the best of the group performing in the "handy hunter" class. The handy hunter class may ask for the horse and rider pair to trot a log, open and close a gate while mounted, jump several fences, and for the rider to dismount and remount. The horse is judged on its manners, way of going, as well as its suitability as a hunter.
The British working hunter is not required to jump obstacles exactly like those met in the hunting field, although a water tray is sometimes used to simulate a ditch, and natural dips in the ground, banks etc are often incorporated into the course in order to make it more challenging.
In some ways, the field hunter is more similar to a good cross-country horse seen in eventing than a show-ring hunter, as it must gallop and jump over varied terrain, jump ditches, coops, up and down banks, and occasionally go through water.
