I made a 40ft fence out of 3/4-inch PVC pipe and plastic snow fence. It works well with our three Shih Tzu dogs. We would never leave them alone in there but it is so much better than tangled leashes when we want to sit outside. Each panel is about 40 inches wide by 30 inches tall (I don't recall the exact dimensions but I wanted to get the most out of each 10-ft PVC length I could. The snow fence is simply 'laced' to the frame with nylon twine. There are a total of twelve frames with four wire tied together so they can be folded up together. The final product is light and doesn't rust but is a little bulky. If need be we use fiberglass rods to hold it in place but they are rarely needed.
