Lifetime Deluxe Dog House, Gray, Large; The Lifetime Deluxe Dog House gives your fur-iend a safe and comfortable space to call his own. This spacious doggy abode is perfect for most medium to large breeds, providing plenty of room to sleep and relax. With its unique and adaptable design, this pet house allows you to create an enclosed back room that better retains heat, or to remove the partition to create a larger interior space. You have the flexibility to adapt the layout to your dog’s growth and preferences. The main door features a weighted vinyl flap to keep out wind and rain, and the adjustable side vents ensure great airflow. When the weather gets chilly, you can easily install a heater (sold separately) and tuck the power cord away for a clean look. The hinged roof has two gas-springs so it stays open for easy cleaning, but won’t slam shut on fingers or paws. A double hand-latch release mechanism ensures the roof won’t open due to wind or prying paws. Plus, this dog and cat house is constructed with durable, impact-resistant, UV-protected, high-density polyethylene (HDPE). The Rough Cut texture has the look and feel of natural wood, but requires no maintenance. Your dog can even lounge on the roof without worry, thanks to the steel-reinforced structure.
