Abstract
This invention concerns a support device for raising an animal from a collapsed position to an upright position. The support structure is a fluid inflatable bag which may be inflated by air or water. The bag has four apertures to receive the legs of collapsed animals thereby enabling the animal to be supported with its legs clear of the ground. In the preferred form the bag comprises three compartments which are separately inflatable. The compartments may be further provided with a plurality of additional compartments underneath or to each side. The bag may be made from a strong canvas outer skin with an interior lining of a suitable plastics material. There is no frame or other form of support member for the bag, it being entirely self-supporting and self-raising by virtue of the fluid pressure of air or water.
