Slide assembly dog whelping box / birthing bed

Dog whelping bed / birthing box. Assembles in minutes with no tools. Includes the slide together pvc bumper rail on the inside. PVC bumper rail protrudes 4" into the interior of the bed on all sides, to provide a "safe area" for the puppies - this helps prevent the pup from getting trapped between Mom and the wall. Removable door slides out easily. Disassembles and stacks flat for easy storage. Constructed of 12 mm Baltic Birch plywood with smooth, eased edges - these pieces are unfinished, ready to receive non-toxic paint or sealer, if you choose.
