Best XXXL dog crate for Leonbergers

A 12-week-old Leonberger — you're already thinking ahead, which is exactly right, because this is one of the few breeds where getting the adult size wrong isn't a minor inconvenience, it's a real problem. Crate size is the single most important factor: too small causes distress, too large removes the den-like security that makes crates actually work. Material matters too — wire, plastic, and fabric all suit different situations. Before I point you to the right crate, a couple of quick questions: is this primarily for home use, travel, or both, and are you starting crate training now while he's a pup?

Good — starting now is the smart move. At 12 weeks he won't need the full adult space yet, and in fact giving him too much room too soon can slow crate training down. What I'd normally suggest for giant breeds is a crate with a divider panel so you can shrink the usable space while he's young and open it up gradually. For a male Leonberger pushing 70kg, you're looking at a dog that will need a minimum of 54 inches in length as an adult. Is he already showing a particularly long or tall build, or is he fairly typical for the breed at this stage?

That confirms it — you need to plan for a 54-inch crate from the outset. My clear recommendation is the Midwest Homes for Pets iCrate in the 54-inch size (also listed as the 'XXL' or '154cm' option on Amazon UK). It's a double-door wire crate that comes with a divider panel, so you start him small and expand the space as he grows — no need to buy two crates. The wire construction gives good airflow and lets him see his surroundings, which suits confident, sociable breeds like the Leonberger well. The floor tray is solid and easy to clean, the folding design means you can move it between rooms, and the gauge of wire on the 54-inch model is robust enough for a large dog. It's genuinely the most practical single purchase for a giant breed owner who's starting from puppyhood. I'd pair it with a non-slip mat cut to fit the tray — the smooth plastic can put pups off settling.

The divider on the Midwest 54-inch is a metal panel that slots into the wire walls — it's not designed for a dog actively throwing himself at it, but for a pup in the early training stages it holds fine. The key is that you don't leave him in there when he's frustrated or under-exercised. If he's going in calm and coming out calm, the divider does its job without drama. Once he's reliably settled and you're opening the full space, the divider just comes out and stores flat. You won't need to replace the crate — that 54-inch frame will see him through to adulthood.

You're well set up. Search 'Midwest iCrate 54 inch' on Amazon UK and you'll find it — just confirm it's the 54-inch/137cm or larger option, not the 48-inch which gets listed nearby. Start with the divider at roughly a third of the full length, give him just enough room to stand, turn around, and lie flat, and increase the space every few weeks as his training progresses. Enjoy the puppy stage — Leonbergers are magnificent dogs.
