My husband and I bought this dog house in a size small for our miniature dachshund to hold her Fresh Patch.  The inside dimensions are perfect for the standard-sized patch (16"x24").  When the package arrived, there were a few cracks in the wood and there were a couple of small pieces that had peeled off the roof; not enough to make it worth sending back.  We used clear caulk to mend the minor flaws.  The house was relatively easy to put together with two people and a small electric screwdriver.  Construction seems solid, although we've only been using it for two days so time will tell.  Before we put it outside on our terrace, my husband applied several coats of outdoor wood protection in the hopes of extending its life.  So far our dog has taken to using it for its purpose.  The only thing we need to add is a battery-operated light as the interior is very dark, even during the day.
