Mantrailing (search dog) harnesses developed for special use, following the design of collar and hames harnesses, are not particularly suitable for everyday use, for example, because the leash ring is located on the back of the dog in line with the stomach in order to ensure that the dog is not disturbed by the leash during work. During search work, with its nose on the ground, the dog performs a special movement for an extended period of time, during which it must follow a trail with maximum concentration.
