The dog house is made of tough and durable PP. Its internal large room has volume enough for your dog to play and sleep, and the waterproof materials make sure to sustain outside conditions. The adjustable skylight on the roof and ventilation holes improve air circulation to let odour out and add more fun to the piece. It's super easy to clean, 100% hygienic, leakproof, and does a very good job standing up against the forces of nature, making it a great option for outdoor use.
