The first slow feed bowl I’ve ever tried that significantly slows down my dog’s eating. No more inhaling their food! The bowl measures approximately 2 inches tall by 7.5 inches in diameter. It holds 16 fluid ounces. The interior of the bowl has a raised spiral, which causes the dog to have to move to different areas of the bowl to get the food. Bowls are made of hard plastic and are top rack dishwasher safe. Available in blue and pink.
