This whelping box features a spacious design that offers versatility, suitable for small, medium, and large breed dogs. It adopts a two-room layout, providing an ideal environment for new mothers by allowing them to have their own space once the first two weeks pass—equipped with three removable doors (including one in the middle) to enable open access between the areas. The right side is fitted with fences that promote airflow, maintaining a clean environment for the mother dog, while the left side is sealed to create a wind-resistant habitat for the pups. Constructed with pinewood walls and railings, it is tough and durable for extra strength, and non-slip pads underneath ensure stability during use. Please note that a dog pee pad is not included, and assembly is required.
