How to make a rectangular dog house

To make a rectangular dog house, you can first find a rectangular cardboard box. The cardboard box must be according to the size of the dog to avoid insufficient space. Place the box on the floor with the opening facing up. Use scissors to cut off all the lids of the carton, and then use tape to secure the bare carton to prevent it from being easily damaged. You can wrap the cardboard box with cloth to decorate it, and put a quilt in the box, so that an open-air rectangular dog kennel is completed.
