Our 2 Mini Dachshunds love being able to go in and out when they want to.  We installed a doggie door and this dog pen all in one weekend.  Bought 2 sections and gave them a pretty good size yard. Easy to install and hopefully easy to take down and store in the winter.  May buy one more set in the future.  Only suggestion would be to add one more post for the ends, because we did Not attach the ends together, but attached to the house.
