I bought a #ELSPET 2 in1 Cats Gravity Waterer/Cats Food Bowl, Anti-Spill Raised Side/Anti-Slip Base, Pet Automatic Water Dispenser with Detachable Bowl and 500ml/17 oz Water Bottle from #rankbooster for my pug dog when she was a puppy. She's older now and so fat i plan on buying one in a larger size because they are easy to clean and very useful
