Abstract: A therapeutic horse saddle including a seat, a girth for securing the seat to the horse, and a quick release arrangement for normally attaching the girth to the seat but allowing the seat and girth to be quickly removed from the saddle when desired. The girth may be a packing girth. The saddle also includes a cantle cover constructed of plastic laminate attached to the seat. In use, the cover is designed to fit the body shape and to accommodate the physical disability of the rider for whom the saddle was designed. The cantle cover is also resistant to cracking caused by jolts due to movement by the horse or rider. Moreover, the cover is also resistant to expansion or contraction due to thermal changes. The novel saddle also includes an inflatable airbag attached to the cantle cover for supporting the back of the rider. At least two fenders are attached to the saddle seat, and secured to the skirt near the fender's center.
