The Road Refresher Pet Bowl is an entirely new concept in keeping your pet happy at home and when you are on the move. This ingenious design eliminates spills and can even help reduce pet slobber. The bowl can be filled with water and placed in a moving vehicle, yet will not spill. The bowl limits the amount of water your pet can pick up at any one time, yet holds 54-fluid ounces, so there"s plenty of water for all sizes and breeds. The Road Refresher has a floating plate inside which feeds enough water for your dog to drink, but restricts the flow whenever there is a surge of water, from cornering, braking, kicking, etc. The bowl also has a Velcro(R) base to attach to carpet. May also be attached to plastic, wood or metal surfaces with the additional included Velcro (R) tabs. Made from heat resistant polypropylene.
