A circular outer fence or barrier is secured to the ground. A circular inner fence or barrier is secured to the ground concentrically within the outer fence to form an annular pathway between the inner and outer fences. A central shaft is located within the inner fence which extends upward. A plurality of spokes are secured to the upper end of the shaft at angularly spaced apart positions. A movable barrier having a plurality of flexible straps are secured to each spoke at a position to hang down between the inner and outer fences such that a space is formed between adjacent movable barriers sufficient to receive an animal. A mechanism is provided for rotating the shaft and hence the spokes and movable barriers. Exposed electrical leads are coupled to the straps on the opposite sides of the movable barriers. An electrical source is provided to apply current to the electrical leads as the movable barriers are rotated to encourage the animals to walk, trot, or cantor between the movable barriers.
