How To Choose a Whelping Box?


To determine what size of box you will need to purchase, you need to know the size of your dog and the average litter size for her breed. You want everyone to fit comfortably within the box, with enough room for the mother to stretch out and the puppies to move around. If it is too large, then your dog may feel exposed, making her feel uncomfortable and less secure.

Height is also an important factor. If it is too low, the puppies could escape and be exposed to harmful situations. While if it is too high, the female may not be able to get in and out with ease.


There are pros and cons to each type of material. Generally, a box made of plastic will be easy to clean, and there are different grades of plastic, with some being stronger than others. If it is too thin, it can be broken with enough pressure. Vinyl is durable and lightweight, though there can be jagged pieces if it breaks. Both plastic and vinyl won’t absorb fluids, making them more sanitary and less likely to harbour germs and parasites.

You will want a durable and strong box unless you are going to use the box only once; in that case, you may want to consider a disposable box. Disposable boxes aren’t as durable but may work well, especially for smaller dogs.


The typical design of the whelping box is one with high sides and a “door” for the mother dog so she can get in and out easier while still containing the pups. There should be puppy rails along each side that prevent the mother from accidentally pinning a puppy against the wall and smothering it.

Some may offer handles to make it easier to move from place to place, and the box may or may not have a bottom. The advantage of this is that you can place materials of your preference, making the box lighter and easier to move around.


You will notice that whelping boxes are not cheap, and some are more expensive than others due to the quality of the materials. If you are on a budget, try to find one that fits your requirements and offers the features you desire. If you will be using the box for the long term, it is important to purchase one durable enough to hold up to the rough abuse from various puppies.


Your mama dog will want a comfortable spot for her and her newborns. Line the box with plenty of newspapers for your dog to use as nesting material. You can add additional accessories to the whelping box to make it nice and cosy.

Can I build my own Dog Whelping Box?

Of course- if you’re good at DIY, then why not have a go at making your own.

Whelping Boxes are generally 4ft x 4ft with an overall height of 2 feet (apart from the entrance)– this is to keep puppies from escaping. Mummy Dog should easily get in and out of the whelping box, especially for toilet time. The door is mostly half the size of the rest of the walls. Pigtail installation should be around half the width of your dog’s chest. These are to ensure that your dog remains comfortable after giving birth and can lie on her side. Keeping level with the spine.

You can use some thick Dowling wood or a thin drain pipe/water pipe to make the pigtail. The pigtail is used to protect your newborn puppies from a major accident like being crushed against the wall. When installing, it should be 4 inches minimum from the base of the dog whelping box. When asleep, your mummy dog will not crush the puppies as the pipe will protect them. Strong piping is necessary as you don’t want it to bend or snap and cause any damage to puppies or mum.

Cardboard / Plastic / Wood – Which is Best?

Material Advantages Disadvantages
Cardboard Easy to Dispose of and very cheap Will need more than one throughout the time a pup is in there as all liquid, pee and poop is absorbed.
Plastic Great for Hygiene and Keeping Clean It can be more expensive
Wood Large Breed Dogs require these Must be waterproofed and fit where you need it as they can be very heavy

Quick and Easy 4 step guide to building a Dog Whelping Box

  1. Measure and cut all your sides. Your base should be approx. 4ft x 4ft. The entrance should be low enough for mum to get out.
