Using the Dog Roof Mini is easy. First, make sure you have the Clubhouse Mini for installation. Attach the Dog Roof Mini to the Soft Crate Mini as per the instructions. When you want your dog to enjoy fresh air, simply zip open and roll up the two windows on the convertible roof. If it starts to rain or you want to keep your dog secure, zip the roof closed. As for maintenance, the durable fabric and mesh panels can be easily cleaned with a spray. Just use a mild detergent and water to keep it clean. Remember, this product is designed for small or mid - sized dogs up to 13.5 kg (30 lb), so don't put larger dogs in it to avoid any damage to the crate or discomfort to your pet.
