This house was a snap to assemble and is better than I hoped for at this price. My dogs think they have hit the lottery! The roof opens for air and the floor panels lift out for cleaning. It is elevated above the floor with protective caps on the legs for keeping it safe from moisture. It is the perfect Dog house. I bought a pair for my garage for my furbabies so when I am at work they can guard the place and stay warm!! Love them!
