A Cardboard Whelping Box

A Cardboard Whelping Box serves as a designated space for a pregnant dog to give birth and care for her puppies during their early weeks of life. The primary purpose of a whelping box is to create a secure and controlled environment that promotes the health and safety of the mother and her litter.

Here are some reasons why investing in a quality whelping box is essential for breeding success:

Safety and Security

A Cardboard Whelping Box provides a confined space that protects the puppies from potential dangers. The walls of the box prevent the newborns from wandering away, reducing the risk of injury or accidental crushing by the mother.

Comfort for the Mother

A comfortable and secure environment reduces stress for the mother, allowing her to focus on caring for her litter. The mother’s well-being is essential for successful nursing.

Ease of Cleaning

Whelping boxes are designed to be easy to clean, promoting a hygienic environment for the mother and her puppies. Removable and washable liners or flooring materials simplify cleaning, ensuring a healthy living space.

Temperature Control

Well-designed cardboard whelping boxes come with features like heat lamps or heated pads to maintain an optimal temperature for the puppies. This is particularly important during the first few weeks of life when newborns are unable to regulate their body temperature effectively.

Factors to Consider Before Choosing a Cardboard Whelping Box

There are several factors to consider when selecting the right whelping box for your dog. Let’s take a look at them to help you make an informed decision:

Size and Space

Mother’s Size: Consider the size of the mother dog. The whelping box should be large enough for her to lie down comfortably, with some extra space for movement.

Puppy Space: You have probably gotten an ultrasound to find out how big of a litter your dog is having. This little bit of information will help you ensure the whelping box you buy has enough space for the puppies to move around as they grow. A crowded box can lead to discomfort and potential injury.

Material of a Cardboard Whelping Box

Easy to Clean: Opt for materials that are easy to clean and sanitize. The whelping box will inevitably get messy, so choosing a material like smooth plastic or coated metal can make cleanup more manageable. If you are looking for an affordable, one-time option, you can choose cardboard.

Non-Toxic: Ensure that the materials used are non-toxic and safe for both the mother and the puppies.

Height and Accessibility

Low Entry: The entry point of the a Cardboard Whelping Box should be low enough for the mother to enter easily. This is especially important right after giving birth when the mother may be tired or recovering.

Sides Height: The sides should be high enough to prevent the puppies from accidentally falling out.

Insulation and Ventilation

Adjustable Roof: Some whelping boxes come with adjustable roofs that can be raised or lowered depending on the ambient temperature, offering flexibility in climate control.

Floor Surface of a Cardboard Whelping Box

Non-Slip: The flooring of the whelping box should be non-slip to provide a secure surface for the mother and puppies. This is especially important as the puppies start to explore and move around.

Easy Monitoring

Visibility: Choose a whelping box with sides that allow you to see inside easily. This is essential for monitoring the mother and puppies, especially during the first few weeks.

Access Points: Some whelping boxes have additional access points, such as removable panels or doors, making it easier for you to check on the puppies without disturbing the mother. This also offers convenience when it comes to storage.


Removable Liner: Consider a whelping box with a removable liner or pad for easy cleaning. This feature can save you time and effort, ensuring a hygienic environment for the puppies.

Puppy Rails: Some whelping boxes come with rails to prevent the mother from accidentally lying on or crushing the puppies, enhancing their safety.

Durability of a Cardboard Whelping Box

Sturdy Construction: Look for a Cardboard Whelping Box with a sturdy construction. This is important to ensure the box remains stable and secure, especially as the puppies become more active.

Ease of Assembly

Simple Setup: Choose a whelping box that is easy to assemble. This is particularly beneficial if you need to set up the box quickly, especially when the mother is approaching her due date.
