Built around eight 24 x 24 in carbon steel panels this exercise dog pen creates a 63 in octagonal play space that adapts to small and medium pets. Each panel folds flat for storage or travel and locks in seconds without tools. Eight 3.9 in ground stakes plus sixteen tension straps anchor the enclosure on grass or carpet for escape resistance. A 600D Oxford fabric mat lines the floor with a waterproof barrier while two slide-bolt latches secure the entry door from playful paws.
