Duct tape a large piece of cardboard to the bottom of the plastic tray before installing it in the dog crate (I cut out a piece from the box the crate came in). Having replaced many a broken tray from an excitable dog, I learned simply taping a piece of cardboard to the bottom offers enough cushioning between the bottom of the crate and the plastic tray to keep it from cracking. This can be a huge money saver!
