The Felixmuc Dog Bowls are made of high quality, food grade stainless steel that is non-slip ring and rust resistant. These bowls are perfect for medium and large dogs, as well as small dogs. They feature an extra large capacity of 64 ounces, making them ideal for feeding multiple dogs at a time. The height of 3.5 inches effectively prevents food spills, water, milk, and other messes from spilling out of the bowl.
