LE TAUCI Ceramic Slow Feeder 0.6 Cups Dog Food Dish for Fast Eaters Dimensions: 6"L x 6"W x 1.38"H Purple The veterinarian recommends using a ceramic bowl for your dogs. Plastic slow food bowls are easily damaged by dogs, they will bite and eat by mistake. The surface of the plastic will also fall off during use. The surface is smooth and very easy to clean. Whether you put it under the faucet for rinsing or in the dishwasher, it will save more of your time on cleaning. These ceramic dog bowls are heavy enough(about 1.48kg) and non-slip base so that the dog cannot move the bowl easily while eating.
