This indoor outdoor dog playpen gives small to medium pets a secure, freestanding space for containment at home, on a patio, or while traveling. Built from tough, pet-safe Hdpe plastic, the enclosure connects 8 individual panels, each measuring 21 inches wide by 31.5 inches tall, so the overall height stands at 31.5 inches once assembled. Panels rotate a full 360 degrees at every connection point, allowing the layout to be arranged into round, square, or custom shapes that adapt to available floor space. A dedicated door panel measuring 14.5 inches by 30.5 inches opens and closes with a double latch for simple, secure entry and exit. Suction cup feet grip smooth indoor or outdoor surfaces, and included ground stakes anchor the panels into soil for extra hold during backyard or campsite use. The complete set snaps together without tools, weighs 20.5 pounds, and wipes clean with a damp cloth for easy upkeep between uses.
