PUPPY WHELPING SUPPLIES: The EZclassic whelping box for small dogs offers a comfortable sanctuary for mother and puppies. It’s made of tough plastic and has a high-walled build and internal rails to increase litter safety. It comes with a heavy-duty canvas floor liner and a washable whelping pad and has interior dimensions of 28" x 28" x 18". SECURE BUILD & PUPPY SAFETY RAILS: Our whelping box is made of durable-yet-lightweight plastic injection molding. The walls are connected with strong plastic posts and are tall enough to keep puppies from escaping. The removable internal rails help protect the puppies from being smothered by their mother, and the entrance allows the mother to come and go without feeling trapped. PORTABLE & EASY TO MAINTAIN: Our comfy indoor dog pen is easy to clean and move around! The reusable pet pee pad and canvas liner are water absorbent and machine washable, and you can wipe it clean using detergent or bleach. YOUR PUPS WILL FEEL AT HOME: This padded-bottom indoor dog fence and enclosure is more than just a birthing place. It’s also a safe puppy pen and sleeping area, a recovery enclosure for an injured dog, foldable fencing to organize puppy accessories, and a reusable home for future litters.

We create whelping boxes for all dog breeds and sizes as well as washable pads, heating solutions, and other pet supplies. Made from a labor of love, our EZclassic whelping box is a high-quality, durable, and easy-to-use indoor dog whelping pen. It’s made of strong-yet-lightweight injection-molded plastic and is easy to transport and clean. This box features walls that connect with high-strength extruded plastic posts that are tall enough to keep puppies from escaping. The EZclassic comes with a removable rail assembly that protects puppies from being smothered by their mother and has a front panel with a two-piece door that prevents puppies from escaping. The two-piece door allows you easy access to the puppies and allows the mother to come and go. The whelping box requires no tools to assemble, so setup is easy! Our dog whelping box is lined with a soft, absorbent machine-washable canvas lining and comes with a reusable pet pee pad.
