Abstract:
A urine pad has a hard upper layer, and a sensor positioned to sense urine deposited onto the pad. In preferred embodiments, the pad comprises at least bottom, intermediate, and top layers, where the bottom layer comprises a liquid impermeable material, structured to prevent passage of urine, the intermediate layer comprises a liquid absorbent material, and the top layer comprises a durable material that is sufficiently hard to resist chewing by a dog; and structured so that deposition of the urine on the top sheet will pass through to the intermediate layer.
