A doghouse includes a plurality of side panels connecting a front panel and a rear panel. A roof includes two roof panels each including runners that slidably connect to upper ledges in the front and rear panels. The side panels can be connected to the front and rear panels using hooks on the side panels that are slidably engaged to receiving members in slots in the front and rear panels. Alternatively, the side panels can slidably connect to the front and rear panels using a tee or dovetail joint. The prefabricated doghouse can be disassembled and reassembled multiple times over the lifetime of the doghouse without experiencing significant wear and tear. The doghouse can be assembled and disassembled efficiently by following a series of easy-to-follow steps. A user can disassemble the doghouse, store the doghouse, and easily assemble the doghouse with a minimal amount of time and effort.
