Apparatus for promoting the healing of a hoof or leg injury or disease of an animal, particularly a horse, comprises a strap to be placed around the trunk of the animal and a mounting by means which the strap can be pulled upward. The strap is mounted by way of a balancer to a fixture that can be moved two-dimensionally in a horizontal plane. The fixture comprises a carriage disposed on a slide rail, which is arranged and displaceable on two slide rails oriented at a right angle thereto, wherein the slide rails are arranged in a cuboid or cube-shaped frame. The strap is fastened with the two ends thereof to mutually parallel sides of a two-dimensional cross bar, which at or close to the center thereof is connected to the balance, and is composed of a number of individually tensionable supporting straps having a common, preferably breathable, cushioning pad.
