Heated animal bed

A heated bed for dogs, cats or other animals which can provide a selected amount of heat to the animal depending upon environmental temperatures. The bed includes a hollow blanket casing within which is disposed at least three layers of foam insulation material placed one on top of another. A removable heating element is interposed between two adjacent layers of the foam material and supplies heat to the animal resting on the bed. The amount of heat delivered to the animal is regulated by selectively positioning the heating element between different adjacent layers of the foam material. The heating element is connected to a power source via a step down transformer which converts high voltage energy into lower voltage energy to minimize the danger of serious shock to the animal.
