I titled this review dog without a leash because this is what I wanted for my dog-no leash. I shopped everywhere for an affordable pen for my dog. Trying to decide what size to purchase I called Chris at Wayfair, he guided me all the way with size and even suggested purchasing two exercise pens to allow more room for my dog to roam. Thanks to Chris I did purchase two pens. Never imagined how easy these pens are to put up and take down. In less than 5 minutes my dog is inside enjoying her freedom from the leash. The pens fold up so compact I can slide them between my cabinets. Also fit into my car trunk not taking up a lot of space. Great for the backyard or to take on trips. Thanks Chris and thanks Wayfair for pricing this so affordable. Delivery was right on time too.
