CAB Heavy-Duty Whelping Box – Hygienic Polypropylene Whelping Boxes with Puppy Rails

The CAB Heavy-Duty Whelping Box is a strong, hygienic and easy-to-clean whelping enclosure designed to provide a practical environment for mother dogs and their newborn puppies during whelping and the important first weeks of life.

Manufactured from 6mm thick polypropylene plastic with fully welded internal joints, the CAB Whelping Box combines a durable, non-porous construction with practical features designed to make cleaning, puppy access and everyday care easier.

Unlike traditional wooden whelping boxes, polypropylene does not absorb moisture and will not rot, making it particularly suitable for environments where cleanliness and regular hygiene routines are essential.

Each CAB Whelping Box is fitted with a drop-down access door featuring raised ridges to help puppies gain grip as they begin exploring and learning to move in and out of the box.

The box also includes removable aluminium puppy protection rails, designed to provide additional space between the mother dog and the surrounding walls, helping reduce the risk of newborn puppies becoming trapped or accidentally crushed against the sides of the box.

The CAB Whelping Box is available in three standard sizes, with bespoke dimensions also available to suit individual breeds, breeding environments and specific accommodation requirements.

Heavy-Duty Fully Welded Polypropylene Construction

Each CAB Whelping Box is manufactured from 6mm thick polypropylene plastic, providing a strong and durable enclosure suitable for regular breeding and kennel use.

The internal joints are fully welded, creating a continuous construction designed to be easy to clean and maintain.

Polypropylene offers several practical advantages over traditional wooden whelping boxes. It is non-porous, moisture-resistant and rot-proof, meaning the material itself does not absorb water or other liquids.

This is particularly important in a whelping environment where cleanliness is essential throughout birth and the early stages of puppy development.

Unlike untreated timber, which can absorb moisture and become difficult to maintain over time, the polypropylene surfaces can be readily cleaned as part of a regular hygiene routine.

The robust welded construction also removes the need for traditional wooden joints that may deteriorate through repeated exposure to moisture.

The result is a strong, practical and long-lasting whelping enclosure designed for breeders who require durable equipment that can be maintained to a high standard of cleanliness.

Hygienic, Non-Porous & Easy-to-Clean Surfaces

Maintaining a clean whelping environment is particularly important during the first few weeks of a puppy’s life.

The CAB Whelping Box is manufactured using non-porous polypropylene, which does not absorb moisture into the material.

This helps prevent liquids and contaminants from being absorbed into the structure of the box, making the surfaces easier to wash and disinfect when compared with absorbent materials such as untreated wood.

The fully welded internal construction also provides a practical enclosure for routine cleaning between and during litters.

The polypropylene material is rot-proof, making it suitable for regular cleaning without the deterioration associated with traditional wooden whelping boxes.

These features make the CAB Whelping Box particularly suitable for professional breeders, working dog breeders and private owners who want an easy-to-maintain environment for their mother dog and puppies.

As with any whelping accommodation, regular cleaning and appropriate hygiene procedures remain essential.

Drop-Down Access Door with Raised Grip Ridges

The CAB Whelping Box incorporates a practical drop-down front door, allowing access to the enclosure when required.

The door is fitted with raised grip ridges designed to provide additional traction for puppies as they grow and begin exploring their surroundings.

During the early stages of development, puppies gradually become more mobile and begin learning to walk, climb and move independently.

The raised ridges help provide grip when puppies start moving across the lowered door, making it easier for them to negotiate the entrance as they develop.

The drop-down design also provides a practical means of accessing the whelping area for cleaning, inspecting the enclosure and attending to the mother dog and puppies.

All door fittings, including the spring bolts and hinge, are manufactured from stainless steel.

Stainless-steel components provide durable and corrosion-resistant fittings suitable for regular use and cleaning within a whelping environment.

Removable Aluminium Puppy Protection Rails

Every CAB Whelping Box is supplied with a set of removable aluminium puppy protection rails.

Often referred to as pig rails or anti-crush rails, these are designed to create a protective space around the inside perimeter of the box.

Newborn puppies can sometimes move into the area between their mother and the sides of a whelping enclosure.

The puppy rails help maintain a gap between the mother dog and the walls, reducing the risk of puppies becoming trapped or accidentally crushed when the mother lies down or changes position.

The CAB puppy rails are manufactured from aluminium square bar, providing a strong, durable and corrosion-resistant construction.

The rail assembly is designed to be easily screwed together and can be lifted in and out of the whelping box when required.

This removable arrangement provides several practical advantages:

• Rails can be removed to make cleaning the whelping box easier.
• The aluminium construction is durable and resistant to corrosion.
• The rails can be dismantled for more convenient storage.
• The protective rail assembly can be removed when it is no longer required.

The collapsible design is particularly useful for breeders who need to store their whelping equipment between litters.

Although puppy rails are an important protective feature, they do not eliminate all risks to newborn puppies, and appropriate supervision of the mother and litter remains essential.

Stainless-Steel Hinges, Spring Bolts & Door Fittings

The CAB Whelping Box uses stainless-steel components for its door fittings, including the hinges and spring bolts.

Stainless steel is well suited to equipment that requires regular cleaning and may be exposed to moisture.

Unlike conventional untreated steel fittings, stainless steel offers greater resistance to corrosion, helping maintain the durability and operation of the drop-down door.

The use of stainless-steel components complements the polypropylene construction, creating a practical whelping enclosure designed for long-term use.

Bespoke CAB Whelping Boxes

As we manufacture our CAB Whelping Boxes, we can also produce them in alternative dimensions to suit individual requirements.

Different dog breeds and breeding environments can require different whelping arrangements, and the standard sizes may not always provide the most suitable configuration.

Whether you require a larger whelping box, a smaller enclosure for a particular space or different wall dimensions to suit your breeding requirements, we can discuss the most appropriate configuration.

Bespoke manufacturing can be particularly useful for breeders fitting out dedicated whelping rooms, replacing existing equipment or requiring boxes manufactured to fit specific kennel layouts.

If none of our three standard sizes is suitable, please contact us with your required length, width and height, together with any particular requirements, so that we can discuss your needs and provide a quotation.
