Crate training divides dog owners like almost nothing else. Some swear the crate is the single best thing they ever bought, while others picture a metal cage and assume it's cruel. The truth sits somewhere in between, and it depends almost entirely on how you use it.
Done right, a crate becomes your dog's den - a quiet, safe space they choose to nap in with the door wide open. Done wrong, it's a box for locking a stressed dog away. This guide covers the kind way: how to pick the right size, introduce it without force, and build a positive routine that helps with toilet training, travel, and separation anxiety. If you're still buying the rest of your kit, our complete dog setup guide covers beds, food and gear at every budget.
- A crate gives your dog a den, not a prison - trained properly, most dogs choose to sleep in theirs voluntarily
- Size is everything: big enough to stand, turn around and lie flat, but no bigger, or house training stalls
- Introduce the crate over days with meals and high-value treats - never force a dog inside
- Never use the crate as punishment or leave a puppy in for longer than one hour per month of age
- A correctly sized crate makes toilet training dramatically easier because dogs avoid soiling their sleeping area
Why Crate Training Works
Dogs are den animals. Their wild ancestors raised puppies in secure, enclosed spaces, and that instinct is still there today. A crate taps into it: a covered, enclosed space feels safe to a dog in a way an open room never quite does. That's why so many owners find their dog naps in the crate with the door open, even when the whole house is available.
The practical benefits are huge. First, toilet training: dogs naturally avoid soiling the place they sleep, so a correctly sized crate teaches bladder control in weeks rather than months. Second, safety: a crate keeps a curious puppy away from cables, shoes and toxic plants while you can't watch them. Third, travel and vet visits: a dog that's relaxed in a crate handles car journeys, boarding kennels and hospital stays far better than one that panics in any enclosed space.
Choosing the Right Crate Size
Size is the decision that makes or breaks crate training, so don't rush it. The rule is simple: your dog should be able to stand up, turn around, and lie flat with their legs stretched out. Any bigger and a puppy will section off the far end as a toilet, which defeats the whole point of house training. Measure from the tip of the nose to the base of the tail, add 10-15cm, and match that to the crate's internal length.
For larger breeds, step up to the Amazon Basics Large Crate (91cm). It follows the same design - double doors, fold-flat frame, easy-clean tray - just sized for labs, golden retrievers and similar dogs. The extra height matters more than you'd think: big dogs need to stretch out fully, and a crate that's too short is a common reason they refuse to use it.
How to Crate Train Your Dog, Step by Step
Crate training works when you go at your dog's pace. Rushing it, locking them in on day one and hoping for the best is exactly how owners end up with a dog that hates the crate. Plan for a week of gradual introduction, and let your dog set the speed.
Step 1: Make the Crate a Good Place
Put the crate in a busy family area - the kitchen or living room - not a forgotten corner. Leave the door open, put a soft bed or towel inside, and let your dog investigate on their own. Toss in a few freeze-dried liver treats so going in is rewarding. Don't close the door yet. The goal is simply for your dog to walk in and out freely.
Step 2: Feed Meals Inside
Once your dog is happy going in and out, start feeding every meal inside the crate with the door open. This builds the association that the crate means good things. For the first few days, sit near the crate while they eat. If your dog is anxious about eating inside, put the bowl just outside the door and move it a few centimetres further in each day.
Step 3: Close the Door for Short Stretches
When your dog is relaxed eating inside, close the door while they eat and stay in the room. Open it the moment they finish. Over several days, leave the door closed for a minute or two after the meal, then open it before they get restless. If they whine, wait for a quiet moment to open - letting them out mid-cry teaches them that crying works.
Step 4: Extend the Time
Gradually build up to 10, then 20, then 30 minutes with the door closed while you're home. Give them something good to do: a chew toy or a frozen treat keeps them busy and builds positive association. A tough chew toy is ideal here - it keeps strong chewers occupied without being destroyed in the first ten minutes.
Step 5: Leave the Room
Start stepping out of the room for a minute, then two, then five. Build up slowly so your dog never panics when you disappear. If they're fine for a few minutes, you can start leaving the house for short trips, always with a chew or toy to occupy them. Keep the first few departures to 15-30 minutes and work up from there.
Step 6: Use It for Overnight
For the first few weeks, keep the crate in your bedroom at night so your puppy can hear and smell you - this massively reduces night-time crying. Take them out for a toilet break at least once overnight (roughly every 3 hours for a 3-month-old puppy). As they grow, you can move the crate to wherever you want it to live permanently.
Crate Training Mistakes to Avoid
Using the crate as punishment. If the crate becomes the place your dog goes when they've done wrong, they'll never relax inside it. The crate must always be a safe space, never a consequence.
Leaving puppies in too long. A puppy can hold their bladder roughly one hour per month of age. A 2-month-old puppy needs out every 2 hours. Crate them longer than they can physically hold it and they'll be forced to soil the crate, which destroys the instinct that makes crate training work.
Letting them out when they cry. This is the most common beginner mistake. Every time a dog cries and gets released, they learn that crying opens the door. Wait for a pause, even a brief one, then open. It takes patience, but the lesson sticks within days.
Choosing the wrong size. Too small is uncomfortable, but too big quietly undoes your house training. Stick to the sizing rule above and buy the crate your dog needs now, not the one they might grow into - you can always size up later.
How Long Should a Dog Stay in a Crate?
There's no magic number, but the guidelines are clear. Adult dogs can comfortably manage 3-4 hours in a single stretch, and most can handle up to 8 hours overnight once fully toilet trained. Across a full day, don't leave an adult dog crated for more than half the day, and arrange a dog walker or lunchtime visit if you work full-time hours.
Puppies follow the one-hour-per-month rule strictly: a 3-month-old needs out every 3 hours, a 4-month-old every 4. Every puppy is different, so watch for signs of distress - persistent whining, panting, scratching at the door - and adjust your schedule rather than pushing through.

Final Verdict
Crate training is one of the most useful skills you can teach a dog, and it costs nothing but a few days of patience. The key is always the same: let the crate become a good place on the dog's own terms. Feed them inside, reward every calm moment, and never rush the door-closing stage.
Start with the right size - a medium Amazon Basics crate covers most UK family dogs, step up to the 91cm version for larger breeds, or pick the heavier FurDreams if you've got a determined chewer. Pair it with high-value treats and a good chew toy, and you'll have a dog that treats its crate as the best room in the house.
