Animal dental hygienic device, comprising: A hollow body having an exterior surface and an interior cavity, and being sized to fit within the mouth of the animal and to be bitten thereby. The hollow body having a plurality of apertures positioned along its exterior surface, the apertures extending from the exterior surface to the interior cavity. Each aperture having dental-hygienically active dimensions allowing an animal's tooth to penetrate through the aperture; such that (i) material surrounding the aperture frictionally engages the animal's tooth's outer surface during penetration of the aperture by the tooth, the material surrounding the aperture being of sufficient hardness to scrape the tooth's outer surface during frictional engagement to remove dental plaque, and (ii) a portion of the animal's tooth extends within the interior cavity during penetration of the aperture by the tooth.
