Examine carefully, and have the animal trotted slowly both towards and from you. If the lameness be in front the animal drops on the well quarter, and throws his head up when the unsound leg is placed on the ground. If lame behind he hitches up the lame quarter, and nods the head when the sound leg is placed on the ground. Then determine location. If in foot, the lameness is more apparent on hard than on soft ground. If lame elsewhere, it will be as apparent, and probably more apparent, on soft as on hard ground (except in splint and other exostoses), and is usually some sprain of a ligament between knee and fetlock in fore leg, and in hock of hind leg.
