Has anyone ever used a real baby box for a puppy?

I'm new puppy in a few weeks and I'm getting all my supplies together. Sell a puppy game pen for the dogs is more than $ 100.00, but have a real baby box for $ 40.00. No matter what you choose? Anyone else has ever used a playpen for non puppy? This a Shih-poo

Yes, I made the mistake of buying a box for my cute little baby kittens. It 'was a disaster. The puppies have been constantly getting nails caught in the net. Would "Scream" and whine so loud When they got hung up on the network, it would scare the sugar out of me. We quickly made them something to play until we had a case of large wire.
