This dog pen has literally changed my life!!   I bought 2 sets to create a larger outdoor area for my 3 Schnauzers.     The assembly was very straightforward and I tackled it myself.  I've never before had the luxury of a fenced yard, but I arranged the panels into a shape so that it safely surrounds by back door and the dogs can now easily just go right outside and play freely in the yard.    It is one of the absolute best investments I've ever made.    I especially appreciate it for outings after dark as I don't have to worry about skunks or raccoons getting through the panels---what peace of mind.    The height is just right and the see through design allows me to still enjoy my flower gardens.    This is a winner in every way.
