  • Patent number: 5983835
    Abstract: Animals are trained to stand and stay with all four feet on the ground in the desired position by placing the animal's feet on four stable, elevated, immobilized supports, then praising the animal for standing in the desired position. This process is repeated until the animal has learned the meaning of the command to stand and stay. It is essential that the supports be immobilizable and sturdy enough to support the animal without the animal being afraid it will fall. In the preferred embodiment, the upper surface of the supports are approximately the same size as, or only slightly larger than, the animal's foot, and is covered with a non-slip surface. The support is designed to elevate the animal's foot so that it does not want to remove the foot to the surface on which the support is immobilized. The supports must be immobilizable relative to each other so that the animal is forced to stand in the desired position.
