Blueprints for whelping boxes are fairly standard with most designs based on a 4 - 5 ft. base, with walls 12 inches high or more (higher to 2-1/2 feet if you plan to use the box until the pups start climbing - happens at 6 to 7 weeks old). Railings on the inside of the box are added to protect the pups from a restless mom. To protect the box, a bottom surface is added that is absorbent and washable.
Consider using removable sides to facilitate cleaning and storing the box after use. You can do this by creating grooves out of molding for the side panels and then use eye hooks to hold each panel in place. Make a shelf around the top of the box with wood pieces that are approximately 3 inches to 6 inches. The pups will crawl under these shelves and they will prevent the mother from crushing any of the pups when she moves or rolls over. As an alternative you can use 1/2 inch dowels that will act as rails.

Whelping Box Blueprint
The bottom of the box should have a layer of newspaper followed by a washable material such as a towel. Do not use anything that can be too deep for a pup such as a blanket or wood type chips. You can also buy a commercial whelping box pad. Pads have a downside if the pup crawls under the pad and the mom gets on top and inadvertently crushes the puppy. Newspaper at about 5" deep makes a good bottom covering.
Do not use new carpet. Puppy/dog urine and carpet fibers combine to create an acidic reaction against the skin. Older carpet such as a bath mat that has been repeatedly washing works.

Supply heat such as a heat lamp that will keep the area 85 degrees with the first week, then bring the temperature down each week until 72 degrees in week 6. Make sure the mom and pups cannot reach the lamp.
