Following is a video on how to make a whelping box or dog bed. Last year, our AKC chocolate Labrador Coco Pebbles weighed 85lbs was due to have 9 puppies.  We decided to create a new whelping box with nice material that we can turn into a dog bed after she was done.  As we have three chocolate labs, we wanted to have a big dog bed for our room.  This worked perfectly.
