Made from ceramic. Microwave safe and easy to clean. Dishwasher safe. Non-slip abd heavy enough (2.31lbs) that your dog cannot move easily while eating. Works great with dry or wet food. Slow Down Eating with the ridges and maze pattern helps your dog to eat slower. 8"L x 8"W x 1.8"H Holds approximately 1.5 cups of food/water Had to upgrade sizes as our 90 lb lab needs a bigger bowl! Excellent used condition. No cracks. I hate the lightweight plastic ones so found this cute ceramic option. Looks nice in room verses cheap plastic slow feeders. Ready for your guy or girl who needs to stop woofing their food down.
