I love this so much for my 5-yr-old corgi that I'm going to order a 3rd set.  I have 2 sets now because I have a huge yard, but I also stand extra sections in my garage doorway so she can sit there and watch what's going on in the neighborhood, and another section at the top of the deck stairs.  I have plans to  fence portions of my ravine where she loves to explore.  With this extremely versatile fencing that is so quick and easy to install, I never worry about her 'escaping' to chase rabbits!
