Abstract: A collapsible pet containment apparatus with foldable side walls to enable selective containment of a pet. Embodiments of the present disclosure provide a pet containment apparatus that can be configured from an extended position to a folded position. The apparatus may have a fabric perimeter defining a bottom and side walls terminating around an upper frame perimeter. The upper frame perimeter may be selectively lowered to allow independent entrance and exit from an interior portion of the apparatus, defined by the fabric perimeter, by a pet such as a dog.
