Offer your pet a fresh drink of water with the Radio Systems DDOG-INOUT Indoor Outdoor Dog Fountain. It has a water capacity of 450 ounces and features a patented free-falling stream that entices your pet to drink more. While the constant circulation inhibits bacteria growth, the replaceable charcoal filter removes bad tastes and odors. Dual-water flow improves aeration and helps remove debris, and a foam filter catches debris before it reaches the pump. It also features an anti-bite cord cover and UV-resistant plastic.
