Fits Different Raised Feeders: The stainless steel water bowl with internal diameter of 7.2” and external diameter of 7.8” can be used in a raised feeder stand with opening diameter between 7.2” and 7.7”. Please measure your elevated feeder openings before buying. No Spill & No More Mess: The splash proof rim and floating disk prevents water from overflowing and splashing to keep floor dry and tidy. It also keeps dogs’ mouth hair or ears from getting wet and dripping water everywhere, especially for messy drinkers and dogs with long ears or long beard. Also great for cats that like to play with water. Slow Water Feeder: Floating disk design makes a small amount of water come out of the holes when dogs’ tongue presses the disk, which effectively helps slow down a sloppy drinker to avoid choking, vomiting or gulping. It also prevents dust, dirt or pet hair from falling into the water to provide your dog with clean water.
