Abstract: A rod-shaped animal restraining device, the length of which is adjustable to fit securely under tension between two vertical walls such as the walls of a bathtub or shower stall, the rod shaped restraining device including an attachment for easy securement of an animal to the rod. Adjustment of the length of the rod-shaped device is preferably accomplished by providing a lever activated length adjustment device, such that pivoting of a lever changes the overall length of the rod-shaped device. The device is simple, lightweight, made of non-corrosive materials, and can be quickly and easily installed between two opposing vertical walls. The device thus enables pet owners to securely restrain their pets while the animals are being bathed indoors.
