Abstract: A wheelchair for animals includes a harness support frame having first and second lateral supports spaced from each other and a width extender adjustably connected between the first and second lateral supports, first and second knuckle clamp assemblies where each one of the first and second knuckle clamp assemblies has a first clamp component and a second clamp component, a plurality of harness connectors attached to the harness support frame, first and second leg assemblies where the second clamp components receives a leg assembly proximal end of one of the first and second leg assemblies, first and second wheels where each one of the first and second wheels is rotatably connected adjacent to a leg assembly distal end of one of the first and second leg assemblies, and a harness assembly detachably connected to the harness support frame.

Abstract: The stabilizer for shoeing a horse is trailer-style apparatus for securely holding horses for close work such as shoeing operations or veterinary procedures. The unit consists of an open-back rectangular perimeter frame with a trailer hitch assembly and an outboard-mounted wheel assembly on each side. The support frame consists of a vertical support in each corner connected by an upper and lower horizontal support on the front, right and left sides and an upper support on the rear side. Mounted in the center of the right and left sides are adjustable retainer bars which slide horizontally inward to restrain the sides of the horse. Elongated spines with retention notches are mounted upon the retainer bars and allow the handler to attach a number of chains for further restraint purposes. An underbelly harness, a back restraint strap, and a neck restraint strap are also connected to the spines and restraint bars.

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: An animal lift apparatus comprises a lift. The lift includes a rigid support sheet, wherein the rigid support sheet is capable of supporting an animal. A lifting mechanism is capable of raising or lowering the rigid support sheet to a desired position. The rigid support sheet is supported in a raised or lowered position by at least one lift arm. At least two wheels are connected to the lift to allow the animal lift apparatus to be rolled to a desired location. A release is capable of being engaged to enable the rigid support sheet to be raised or lowered to the desired position. At least one belt is capable of strapping the animal to the rigid support sheet. The rigid support sheet may also include a waste portal. A waste container may also be included, wherein the rigid support sheet is sloped such that waste from the animal may be directed toward the waste portal via the sloped rigid support sheet. Waste then flows through the waste portal into the waste container. At least two I.V.

Abstract: An animal support apparatus for providing supplemental vertical support to ease strain on portions of an animal during a process of medical rehabilitation is provided. The animal support apparatus includes an elongate flexible sheet member for positioning about a belly and sides of an animal. The sheet member is generally oval-shaped and has a plurality of apertures for receiving the limbs of the animal. The sheet member comprises a substantially flexible cloth material and has a cushioned material attached to an inner side of the sheet member. The sheet member has a plurality of handle sections for lifting the sheet member upward such that limbs of the animal are relieved of a portion of a weight of the animal to facilitate the process of medical rehabilitation of one of the limbs or other related parts of the animal.

Abstract: An apparatus for use in transporting and lifting immobile large animals. It has two major cooperating components: a cart and a lift. Both have tubular frame constructions with fabric releasably attached to the frames for supporting an animal. The cart has large wheels for maneuverability even over rough terrain to an animal needing care. The fabric can be unsnapped from the cart frame to more easily load the animal. The legs can be pivoted outward, allowing the cart to be lowered to the ground for greater ease in loading an animal. The cart, with the loaded animal, fits over a lowered lift. The lift has an upper frame which can be raised to bring the supported animal to a desired level. It has wheels on its base frame to allow it to be wheeled to a desired location. Two separate motor-driven lifting mechanisms are used to raise the upper frame, capable of lifting up to 300 pounds. Belts are provided to secure an animal on the lift.
