Black HDPE panels rise 31.5-in from the floor on this 12 panel puppy pen, a height that discourages climbing and hopping far better than a low rail. Suction cup feet grip laminate, tile and sealed hardwood so the enclosure does not creep across the room when a dog leans on it, and stakes take over once it moves onto grass. Each connection snaps in by hand, meaning setup and takedown need no screwdriver. The 14.5-in by 30.5-in gate opens on twin latches. Pet-safe plastic sheds mud and drool with a wipe, and the whole 30-lb set stores flat between uses.
