A kennel includes a plurality of side panels that are connected or coupled together with a gate panel to form an enclosure. The gate panel has a pair of ends that are configured for connecting to the side panels and allow access into and out of the enclosure via a doorway positioned between the ends. A door configured for opening and closing the doorway is positioned therein, and has a frame member directly and rotatably attached to a doorway frame member to form a compact door and doorway combination in the gate panel.
