Best crate for Tibetan Mastiff puppy

A 14-week-old Tibetan Mastiff is already a sizeable puppy, and you're right to think ahead — at 70kg adult weight, you're looking at one of the largest dog breeds there is, so buying twice would be expensive and disruptive. Crate size is the single most important factor here: too small causes real distress, but too large at the puppy stage removes the den-like security that makes crates useful for settling and toilet training. The good news is you can solve both problems with one purchase if you choose a crate with a divider panel. Before I point you in a specific direction — is this crate primarily for home use, travel, or both, and are you crate training from scratch with this pup?

Perfect — that makes the decision straightforward. For home-only use with a giant breed you're training from puppyhood, a heavy-duty double-door wire crate with a divider is exactly what you need. Wire gives you ventilation, visibility, and easy cleaning, which matters a lot during toilet training. The divider lets you start him in a smaller, cosier section now — big enough to stand, turn, and lie down, but not so large he treats one corner as a toilet — and you open it up in stages as he grows. What's his current rough size or weight, so I can confirm the right internal dimensions for the divider setting you'd start on?

That's helpful. At 12kg he's already solid, and Tibetan Mastiffs grow fast through adolescence before filling out fully around age three. For a dog heading to 70kg, you're looking at needing an internal space of roughly 130cm long by 90cm wide at adulthood — that puts you firmly in XXL territory. My recommendation is the MidWest Homes for Pets iCrate in the 54-inch (137cm) size. It comes with a steel divider panel, double doors for flexible placement in a room, and folds flat if you ever need to store it. The gauge is robust enough for a large breed, and at that size it's genuinely future-proof. Start him with the divider giving him about 60–70cm of length now, and move it back every few weeks as he grows. It's widely available on Amazon UK and is one of the most consistently well-reviewed large-breed crates on the market.

That's a fair concern and worth being honest about. The MidWest iCrate is solid for most dogs, but Tibetan Mastiffs are genuinely powerful and, as you say, determined. If he takes to crate training well — which most puppies do when introduced positively and gradually — it'll hold him without issue. However, if by adolescence you find he's bending the bars or working the latches, that's a signal to move to a heavy-duty welded steel crate like the ones from Impact Dog Crates or Gunner. Those are significantly more expensive, so it makes sense to start with the MidWest at the puppy stage and only upgrade if you need to. The key is making the crate a genuinely positive place from day one — cover three sides with a blanket, feed meals inside, never use it as punishment — and the vast majority of dogs, including giant breeds, settle into them without ever testing the limits.

Somewhere he can see and hear family activity but isn't in the middle of constant foot traffic — a corner of the living room or kitchen works well. Avoid anywhere with temperature extremes: no direct sun through a window and away from radiators, since Tibetan Mastiffs have a thick double coat and can overheat easily. Covering the top and sides with a blanket or a purpose-made crate cover helps reinforce that den feeling, especially in the early weeks. Once he's reliably settled in it, you can move it to wherever suits your household best.
