The three different sizes allow you to adjust the capacity to suit your dog. The designer Pappy dog bowl is more stable than a conventional plastic bowl due to its high weight. The bowl features additional stoppers on the bottom for increased stability. It is microwave and dishwasher safe, making it perfect for everyday use with your dog. You can warm your dog's food in it if needed, or clean the bowl in the dishwasher after feeding. The integrated grip indentation allows for easy lifting of the bowl. The outside of the bowl is matte, while the inside is glossy for hygienic reasons.
