Abstract: The present invention provides devices and methods for reducing compressive and concussive forces to the back of an animal. Such compressive and concussive forces can cause pain, soreness and discomfort to an animal carrying a load on its back. The invention takes into account the structural and physiological characteristics of an animal's back that correspond to areas of high concussive and/or compression forces between the animal's back and a load applied to its back. In one embodiment, the invention provides a pad for use between a load interface and the animal's back. The pad is made of at least two distinct materials, each having a different resistance to compression and ability to absorb concussive and compressive forces. In one embodiment, a first material is sized to fit over a substantial portion of the animal's back covered by the load interface.
