【Rust Resistant & Rubber Bottom】Made from genuine stainless steel. If properly cared for, your stainless steel dog bowl will last for years. Regular metal bowls that try to pass themselves off as stainless steel when they are actually regular steel (carbon steel) will rust in no time. The added slip resistant rubber rim on the bottom prevent the bowl from sliding around and reduce noises while your dog eats. 【Easy to Clean & Dishwasher Safe】Dog bowls made out of stainless steel can easily be cleaned with mild dish soap and warm water. In addition, they are also dishwasher safe, making for easy cleanup. Besides, the rubber ring can be removed to wash these bowls thoroughly in the dishwasher. 【Stackable Design for Easy Storage or Travel】With a considerate and convenient design, these bowls stack easily inside one another for easy storage or travel. Durable for long time use and healthy for your beloved four-paw companions.
