Four panels is the compact option, making an 82cm square that fits in a corner, beside a desk or in the back of an estate car. Where it differs from lighter pens is the gauge — 2.5mm wire in both directions and a 7.65kg finished weight, which is heavy enough that a bored dog leaning on it moves themselves rather than the pen.

The door is a step-through with a locking latch, at 36.5 x 40cm, so you get in and out without lifting a panel or climbing. Four ground stakes come in the box for use on grass, and they matter more outdoors than people expect: without them a light pen creeps across a lawn over an afternoon as a dog pushes at the sides. It knocks down flat for transport, so it can live in the boot and come out at a campsite or a relative's house.

Sized for small dogs and puppies. At 60cm tall this is a boundary rather than secure containment — a medium or large dog will step over or scale it, and it is not intended to hold one. Used for what it is, a puppy pen and a portable safe square, it is noticeably better made than most at the price.

Who it's for: Puppy owners wanting something sturdier than a folding fabric pen, and anyone needing a compact, transportable safe space for the car, campsite or holiday let.
