10 Best Whelping Boxes for Dogs

A Whelping box (also called Birthing Box or Nesting Box or Whelping Pen) is a secure and comfortable place where your female dog will deliver her puppies. 

It is essential to get a whelping box before the last weeks of pregnancy so that your female dog becomes comfortable with it and will feel safe to keep her little ones there.

Perfect whelping solution that fits all large, medium & small dogs of every breeds.

Every whelping box has an entrance door with an adjustable height. This allows the mother to come and go safely as she pleases while keeping the pups secure. Also includes a 360-degree puppy protector rail (“pig rail”) to keep your puppies safe and secure. The puppy protector rail is essential during birthing to ensure newborns have the protection they need.

The PUPez Whelping Pen is super easy to assemble. Requires only 1 person to assemble and disassemble in just a couple of minutes.

The PUPez Whelping Box is made from extremely durable PVC. It is lightweight and portable and is built to last for years.


The quality of the whelping box far exceeded my expectations considering the price.

Pros: easy assembly, easy to wipe material, inner rail for pups, plenty of space for my Cavalier & pups, tall wall to prevent drafts.

I would definitely recommend this budget-friendly whelping box!



This is a sturdy whelping pen; well designed and easy to assemble. I have a German Shepherd who’s due on 11/12, and she’s able to fit comfortably into the pen. I also love that you can get a second one and attach it to the first pen to create a play and potty area outside of the denning area.

The price is incredible as well!



Easy assembly, excellent size and dimensions, reasonably priced, easy clean up, and I’m looking forward to ordering a second one to attach to the first one.

Worth the investment.

This whelping pen works great and would work well for a Breeder with 1 female or 5. It’s easily cleaned and the puppies don’t get squished under Mom if rolls in her sleep. I’d recommend it to anyone.

4. EZclassic Whelping Box

This whelping box is sold complete with rails*, one absorbent pad, and one heavy-duty canvas floor liner. Wall height = 18 inches

Moulded Plastic. The walls are made by injection moulding. The plastic is tough and light while providing great wall strength and rigidity. Walls are connected with a very high-strength extruded plastic post. Under normal use, your box will serve for multiple litters.

Cleaning. Clean the plastic with general-purpose detergents and disinfectants, including bleach. This material, used together with our whelping pads, will ensure that your box is clean and tidy throughout the whelping process. The use of our washable pads will significantly reduce your cleanup effort. The liner that is included is also machine washable and water-resistant.

Size Consideration. Molded plastic boxes are usually not suitable for large, heavy breeds such as German Shepherd Dogs, Bernese Mountain Dogs, etc. Generally, bitches should be smaller than 60-65 lbs. But this weight guideline may vary depending on the temperament of the bitch.

Delivery was prompt and the product arrived in perfect condition with clear instructions for simple set-up. It has many convenient features that make whelping easier. It is easily stored and very convenient to move around. We use it for whelping and as a puppy showing box in and outside of our home. We highly recommend this product

This is truly the whelping box of whelping boxes. It’s so easy to put together and you don’t need any tools except that little L shaped wrench that John sends with the box. There’s also a tarp to go underneath. It can be done by one person. The quality is fantastic. Great workmanship. I’m impressed

Kimberly Anderson


I shopped around, this whelping box is the best. It’s worth every penny. The workmanship is unbeatable. No rough edges anywhere, very smooth & takes minutes to assemble. Height & door options are great. Will be easy to keep clean, will last for years. My dogs all love it & took to it immediately! Shipment depends on where you live, I got mine in 5 days. You need a whelping box…this is the one! Love it!

Kyleigh Hamilton


I am extremely pleased with this whelping box. This is the best whelping box on the market for the price FOR SURE. My momma dog LOVED IT IMMEDIATELY she was sleeping in it a week before her pups came. I set it up all nice and perfectly for her. 9 puppies came shortly after and they are all 20 days old now and thriving. 10/10 recommend!!!



Got this for my Rottie and she loves it so much. She couldn’t wait for us to put it together. Very well made and easy to put together. Its plenty big enough for her and she weighs 118 lbs when not pregnant. Love how you can take the pvc pipe out for when the puppies get bigger to give them more room. Great customer service and quick shipping. Thank you so much!
