Review on Pet Trex Foldable Metal Pet Exercise Playpen Collection - Premium Indoor/Outdoor Enclosure with Gate for Dogs, Cats or Small Animals by Dawn Webster

It can be folded into different shapes, mine is upside down in a 2x4 rectangle so the door with the pot pads inside stays open. My two new little puppies are potty trained and doing great. Now they get in there automatically and know what that is for, what a big help. A week of training! Too young to go outside and wait for puppies to be vaccinated. This pen will continue to have many uses in the future, folds down to 2 x 2 feet making it great for travel. The seller was also very accommodating and answered my questions immediately! I have small pom poms so the size will be ok and I am very happy with the quality. Love it! I would also like to add that the breeder recommended this for training and when they get a little older we can take them outside and they will have the same mental picture for training.
