Keeping dog crates clean is one of the responsibilities of the dog owner. Dogs have a natural distaste for living around their own waste. By keeping the crate clean, it is easier to train them to do their thing only in specified places. Wire dog crates are so much easier to clean than those made of other materials. Metal pens are also more durable.

Metal dog crates may be made of stainless steel or aluminum. Steel dog crates have the advantage of being durable and not easily destroyed by the dog or the elements. If it is a wire metal crate, make sure that the wires are spaced so that the dog cannot squeeze their paws or heads through the spaces. This is especially true for playful little puppies that can hurt or escape. Dog crates with larger spaces are easier to keep clean.
