Crate training a Pug with overheating issues

Crate training works when the crate genuinely feels like a safe, comfortable space to your dog — and for a breed like a Pug, the type of crate you choose matters even more than usual, because poor ventilation can make the whole experience miserable and even dangerous. The right introduction approach matters too; rushing it almost always backfires. To point you in the right direction: what breed and age is your dog, are you starting from scratch or trying to undo a bad experience with the crate, and is this mainly for home use or do you need it for travel as well?

That's exactly the right thing to be thinking about. Pugs are brachycephalic — that squashed face means they can't pant as efficiently as other dogs, so they struggle to cool themselves down even in mildly warm conditions. A solid-sided plastic crate or a heavily covered wire crate in summer is a bad combination with a Pug. Before I give you a specific recommendation, can you tell me roughly where the crate will live in your home? A spot that gets afternoon sun, for example, would affect how important additional airflow measures are on top of the crate itself.

Good — a fan nearby is genuinely helpful, and the living room placement means he won't be isolated, which makes the training process easier. For Monty, I'd go with the MidWest Homes for Pets iCrate in a size 24 or 30 inch. It's an open wire mesh crate on all four sides and the top, so airflow is as good as you'll get from any crate — there are no solid panels trapping heat. It folds flat, has a removable tray for cleaning, and crucially for a Pug who's learning, it doesn't feel like a sealed box. The dual-door version gives you flexibility for how you position it in the room. For a 9-month-old Pug, the 24-inch is usually the right fit — big enough to stand and turn around, small enough to feel den-like rather than exposed. You can find it on Amazon UK under 'MidWest iCrate single door or double door 24 inch'. Pair it with a cooling mat inside rather than a thick padded bed in warmer months and Monty should be genuinely comfortable.

You can cover three sides lightly — the back and both ends — with a thin breathable fabric like a cotton sheet, leaving the front door and at least one full side completely open. That gives a den feeling without trapping heat. Avoid fleece or heavy throws entirely in summer. The key is that air needs to be able to move through, not just around the outside. With the fan at a gentle indirect angle and the front open, Monty will have airflow without a draught blowing directly on him, which some dogs find unsettling.

Take it in stages and let him lead the pace. Start by leaving the crate open in the room with the door off or secured open — let him investigate it on his own terms over a day or two, with treats scattered just inside the entrance. Once he's going in voluntarily, start feeding meals just inside the doorway, then gradually move the bowl further in. Only once he's relaxed eating fully inside should you start briefly closing the door — just for a minute while he's eating, then open it before he shows any anxiety. Build duration gradually from there. The goal is that he never reaches the point of distress; if he does, you've moved too fast and need to go back a step. With a Pug, keeping the space cool throughout training matters too — a stressed, overheated dog will form a negative association very quickly.
