Abstract: The training device of the present invention is worn by a dog or other small quadruped and sounds an audio alarm when the animal urinates. This device includes a flexible absorbent panel assembly, a saddle assembly, a back strap assembly, and a front strap. The absorbent panel assembly absorbs the urine discharged and contains embedded moisture sensing electrodes. This panel assembly is supported beneath the animal by the back strap assembly and the saddle assembly. The back strap assembly, passing over the animal's back, supports the rear end of the panel. The saddle assembly, passing over the animal's withers, support the forward end of the panel. The front strap prevents posterior movement of the saddle and panel assemblies. The saddle assembly contains electronics for detecting moisture in the panel assembly, a battery, and an audio alarm. The the panel assembly is releasable from the saddle assembly and is washable. Separate embodiments of this invention are suitable for training male and female animals.
