The PawGiant Dog Kennel Outdoor Dog House with Roof 4ft x 4.2ft x 4.45ft is perfect for medium to small sized dogs. Made of high-quality metal and fully welded at the seams, this kennel features reinforced ground spikes that effectively enhance the stability and prevent being knocked over or damaged by large dogs. The kennel is also equipped with non-slip rubber feet that effectively prevent the floor from being scratched. The roof is made of durable UV resistant and waterproof Oxford cloth that can easily be removed and cleaned. The lock is a brand new type of gravity-based invisible door latch that prevents smart dogs from opening the door on their own.
