Review: Perfect for puppies and growth - Highly recommend product. Had a litter of 9 and quickly need a 2nd room and then a 3rd when growing! Pieces are put together in a way you see the room.
Review: Great product - Absolutely the best product for breeding I love the way you can add on. I breed Yorkies, Maltese, red teddy China poodles and Biewer Terriers. I have bought off Temu and the ones I got were made of something besides wood, I think particle board, they fell a part, so don’t waste your money, get a EZWhelp product.

## Features

- WHELPING BOX ADD ON: EZclassic 3-Wall is Ezwhelp's newest whelping solution! This whelping box add-on features a modular construction for your indoor puppy pen and thick, molded plastic for a sturdy enclosure. This box allows you to add a third wall, allowing plenty of space for your dog and her puppies! This add-on room connects to Ezwhelp's EZclassic whelping box with rails to give your dog's whelping box an extra potty room, play room, or even a spacious play yard!
- STURDY DESIGN: Our add-on dog fence for whelping boxes for dogs and puppies is made of easy-to-clean, strong, and sturdy plastic. Even for medium-sized breed dogs, the panels of the pet pen act as a barrier or pet fence. Unlike flimsy dog cages and dog houses, this 3-wall add-on features extra-rigid panels that ensure our dog house won't tip against the most unruly puppies. You can extend your EZwhelp whelping box without worrying about tipping or wobbling!
- EASY ASSEMBLY: No need to spend hours searching for the right dog accessories or tools when building a whelping box or puppy play pen. Build your own puppy playpen or breeder box in a few minutes using our add-on room. No screw, clips, or other parts - just snap them together and you're done! You can assemble your 3-wall whelping box for large breed dogs and small breeds more easily. Plus, it also has easy to use doors for an adjustable space for your dogs and puppies to move and roam free.
- CUSTOMIZABLE LAYOUT: Whelping box extensions come in 3 different sizes, (28x28, 38x38, 48x48), allowing you to customize the layout of your indoor dog pen or playground and find the perfect space for your dog's home and litter. Add an extra potty area to your dog playpen indoor or a play room to give your puppy litter more space to exercise. Maybe even an entire play yard! Connect multiple whelping plastic box extenders to create a large play yard for your pets to enjoy!
- PACKAGE INCLUDES: Each 38x38 dog playpen add-on room package contains (1) Front Panel set with doors, (2) 28" side panels, (3) 10" side panels, and (5) Posts with caps. Liner, pad, or rails are NOT included. EZclassic add-on rooms are meant to be extensions to EZwhelp's EZclassic whelping box with rails. They are not designed to be standalone whelping pens.

### ⭐⭐⭐⭐⭐ Quality product
*by T***J on January 22, 2025*

I ordered the 28x28 whelping box for my small breed ( 15lbs at adulthood) puppies. It’s made of quality material and was easy to assemble. With the guard rails, it was maybe a bit small. Since I slept in the whelping room, I took them out, but if I had to do it over, I’d probably go up one size. However, when I decided to expand the box, it was super easy. I ordered the extension, and again, very easy to assemble. I turned the doorway upside down so my small puppies could get through it. I highly recommend this product. Also, the manufacturer is very responsive to requests.
