Abstract: A mobile prosthetic apparatus for disabled four-legged animals comprises a cart having a chassis. The chassis includes a front subassembly detachably mounted to a rearward subassembly. A primary wheel is mounted to the frame of the chassis at each side of the rearward end and a set of swively mounted secondary wheels is mounted to the frame at each side of the forward end. A yoke extends across the frame at the forward end and is movable from an active position spanning the side walls of the frame to an inactive position away from one of the side walls to permit entrance and exit of the animal from the cart.

Abstract: A mobile orthosis for a four-legged animal such as a dog having injured rear quarters comprises a wheeled cart to which the animal is to be harnessed, the cart having a yoke attachable to the animal's thorax, a hip support member for carrying the animal's rear quarters, and a shin support for the animal's rear legs. A preferred embodiment comprises a two-wheeled cart having a pair of adjustment blocks each having a plurality of axle holes, the axle being positionable with respect to the cart to approximate a balanced support of the rear quarters.
