  • Patent number: 6216636
    Abstract: An device for assisting four-legged pets to walk during periods of convalescence from foot, leg, or hip surgery or injury. A sling portion is connected to two handle grips. The sling portion may be disposed under the chest of the animal in the case of debilitated front legs, or under the abdomen in the case of debilitated hind legs, and the handle grips grasped by a human user to help support or lift the pet. The invention is particularly useful for assisting a convalescent pet to take beneficial walks without having to bear full weight on injured limbs or hips. A version of the device is disclosed which may be adjusted in length to accommodate the size of the animal and the height of the user.
