What is a whelping box?

A homemade whelping box is also known as a nesting box or whelping pen.

It is designed to protect puppies during birth (whelping) and in early life by keeping them safely contained.

They will be protected from cold, and safe from the danger of getting crushed or suffocated by the mother.

This whelping box design is long lasting, easy to clean, and a sanitary place for your puppies.

Plywood is NOT a recommended material to use for building a whelping box.

Plywood is a very porous material, because it can trap bacteria. This could lead to sickness in your litter.

It is also very difficult to clean, and not a long lasting option for a quality DIY whelping box.

Building a cardboard whelping box will achieve the same result as plywood, and is not a recommended solution.

With a few basic tools and materials, you can build this homemade puppy whelping box over a weekend.

Overall Design

echo GSP DIY whelping box

We breed German shorthaired pointers so this design is based on a box to fit a 55-75 pound dog.

Because German shorthaired pointers are a medium to large breed, so they will need some extra room to move around in their whelping box.

This design boasts a spacious 4 foot by 4 foot area that is also around 24″ high preventing the puppies from climbing out.

Door design

Door design DIY whelping box

The door is a very important part of the homemade whelping box and also a great safety feature.

It allows mom to comfortably get in and out of the whelping box, while also containing the puppies inside.

This design has adjustable doors to assist in all stages of the puppies lives.

You can remove both doors to allow for easy access to the puppies and for mom to easily get in and out.

After about 2 weeks the puppies will be getting more mobile, therefore they will need additional space.

Adding the thin door option will still allow mom to easily get in and out but still contain the puppies in the whelping box.

As the puppies get older and larger, the thicker door is a great option. Keep the small door slide removed.

Mom will still be able to get in and out, but the whelping box will still contain the puppies safely inside.

After mom has weaned the puppies, both doors can be used for the final stages of the puppies lives. This will assist in containing them in your homemade whelping box.

Pig rail design

Pig rails are a very important part of your homemade whelping box.

Suffocation from mom laying on the puppies and pinning them between her and the wall is an enormous risk to newborn puppies.

Pig rails should be designed to allow room for puppies to crawl behind mom safely in the event of her laying down on them and pinning them against the wall.

Pig rails are a safety device that serves as a buffer between mom and the wall in a whelping box.
