This extra-large whelping box provides a spacious, enclosed area designed to support mother dogs and growing puppies with a practical 2-room layout. Built from waterproof PVC panels, it’s designed for easy wipe-down cleaning and long-term indoor use. The adjustable double-door entrance helps manage access as puppies grow, while the center divider height can be adjusted to change how the spaces are separated. Two oversized, washable pee pads are included to help protect floors and simplify cleanup. Clear directional markings on the feet help make assembly faster and more straightforward.
