All week I have been working on a new dog pen for my puppies. I was quite pleased with the results considering I am NOT a builder. It is made out of 2x4s and some chicken wire. God also supplied several of the materials I needed, so I didn't have to even spend much on it! It measures 4 ft. long by 2 ft. wide. I think it will work very well, and give me a place to keep them at night.
