The Retriever 36 in. Step-Thru Exercise Pen for Dogs is the perfect next step for your puppies when they have outgrown the whelping box. This affordable pen has eight 24-inch panels (one of which has a double-latch door) and more than one can be combined to make a larger play area for bigger litters with room for toys, a bed, and a potty area. The sturdy steel is bite resistant and the pen folds flat for easy storage. It also comes in 24-inch and 48-inch heights.
