Key Features:

• Secure Dog Whelping Box: This 48” x 48” x 18.1” / 38.6” x 38.6” x 18.1” / 28.3” x 28.3” x 18.1” / 59.8” x 59.8” x 24” whelping box provides a cozy and durable space for mother dogs and puppies. Made from sturdy, burr-free PVC, it resists deformation for long-lasting use, providing your pets a dream home while giving you peace of mind. Note: Please check the dimensions to ensure a perfect fit for your breed.
• Easy to Install and Clean: This whelping box for dogs provides hassle-free installation to minimize your workload. Follow the clear instructions, snap the walls together, and secure with the included four screws using the provided screwdriver. Installation takes just minutes. The smooth walls are easy to wipe clean, with no hidden corners for dirt, ensuring your dog's health from the start.
• Remarkable Stability: Upgraded to a height of 18.1 / 24 inches, this whelping box with rails prevents the mother dog from jumping out once all the panels are installed. Velcro secures the pee pads to the corners, ensuring the walls stay in place without tipping or shifting. The snap connections feature convex cutting, preventing cracks during disassembly and keeping the panels tightly in place.
• Comprehensive Safety Design: This puppy whelping box is more than a temporary birthing space; it serves as a long-term play and sleep area. When you remove some of the detachable panels, the mother dog can freely enter and exit, while the puppies remain safely inside. The special rail system prevents accidental crushing, reducing the risk of suffocation. Expandable sections allow for flexible growth as the puppies need more space.
• Complete Care and Feeding Kit - In addition to the washable pee pads, the whelping box for dogs and puppies includes a complete care and feeding kit (measuring tape x 1, feeding set: syringe x 4, connector x 4, pet bottle x 1, bottle cap x 2, cleaning brush x 1, needle file x 1, feeder x 1, lid x 2) to support your puppies throughout their growth stages.
