Review on ALLISANDRO Small Animal Playpen: Indoor/Outdoor Metal Wire Cage, Portable Fence for Guinea Pigs, Bunny, Turtle, Hamster - 11.8x11.8 Dimensions by Angie Love

Bought to limit my dog's movements after knee surgery. He's a chihuahua/small terrier mix so perfect for his size although I wouldn't take a bigger dog than him. Very easy to assemble - you don't even need instructions. It comes with zip ties to make the panels more secure but as we are only using it temporarily I didn't use zip ties. However, without them, the panels can be easily detached. It doesn't really matter to us as our dog is a lazy old pup and doesn't like running very much, but for more active dogs it can be a problem. I love that you can adjust the size of the pen by adding or removing panels and I plan to bring enough panels to make a smaller pen when I go on vacation with my dog. Again, this is a temporary situation, so don't use zip ties, which can be a problem for active dogs.
