Abstract: Systems and methods according to the present invention include a device for delivering non-invasive direct current electricity to the oral cavity of a non-human animal. The device generally comprises layers, wherein an electronic circuit assembly is protected within an enclosure, which itself is protected within a frame. Surrounding the frame, a plurality of traces connect to rails and nubs, which are exposed through the outer mold layer. The rails and nubs act as anodic and cathodic electrodes. When masticated, the non-human animal's mouth (teeth and/or gums) closes the circuit between the anodic and cathodic electrodes, delivering relatively weak direct current electricity to the animal's oral health benefit.
