Crate training a puppy

Build the crate up in short, rewarded steps over days or weeks, never use it as a punishment, and keep each stay short. The UK and New Zealand charities put the ceiling at about three hours, and US guidance at three or four hours for a puppy under 6 months.

Step by step

This is the method Humane World for Animals publishes, which SPCA New Zealand and RSPCA UK follow closely, with Dogs Trust's and PDSA's cautions added. Move on only when the puppy is relaxed at the current step. The whole thing usually takes a few weeks at least, PDSA says, and can take much longer.

  1. Set it up. Soft bedding, water and a chew, in a room where the family spends a lot of time. Fix the door open so it cannot swing shut and frighten the puppy (RSPCA UK, Dogs Trust, PDSA).
  2. Introduce it. Drop treats near the crate, then just inside, then at the back. Let the puppy walk out whenever they like and do not force them in. Humane World for Animals says this can take a few minutes or several days. RSPCA UK keeps sessions to about three minutes.
  3. Feed meals in it. Put the bowl as far in as the puppy will happily go, a little further back each meal (Humane World for Animals, SPCA New Zealand).
  4. Close the door during meals. Open it as soon as the meal is finished, then leave it closed a few minutes longer each time until the puppy stays calmly for about 10 minutes after eating. If they whine to be let out, you went too fast (Humane World for Animals, RSPCA UK).
  5. Add a cue and short stays. Say your cue, such as 'crate', give a treat and close the door. Sit quietly nearby for 5 to 10 minutes, then go into another room for a few minutes, come back, sit again, then let the puppy out. Repeat several times a day, building the time and the distance.
  6. Build to about 30 minutes with you mostly out of sight, calm the whole time. Humane World for Animals says this can take several days or weeks.
  7. Start short absences. Crate the puppy 5 to 20 minutes before you leave, varying the point in your routine, and keep departures and returns matter of fact (Humane World for Animals, SPCA New Zealand). Keep using the crate for short spells while you are home too, so it does not always predict being left.
  8. Watch the first few absences on a camera if you can, which VCA suggests, and at any sign of worry go back a step: whining, scrabbling, panting, excessive barking, cowering or aggression (RSPCA UK, Dogs Trust, PDSA).

How long can a puppy stay in a crate?

Nobody agrees on one number. The UK and New Zealand charities are the most cautious, at about three hours or less, and US guidance runs higher. Treat them as maximums for a single stretch in the day. RSPCA UK and SPCA New Zealand both say it is never acceptable to shut a dog in a crate all day while you go to work.

SourceGuidance
RSPCA UKNever all day while you work. An adult who sees their crate as a safe haven is normally happy to be left for about three hours.
PDSA (UK)Never more than 3 hours at a time, and less if the dog is not used to it. Some dogs will not cope even that long.
Blue Cross (UK)Build up gradually to a maximum of three hours, which it calls the maximum a dog should be left in a crate.
Dogs Trust (UK)No crate figure. Dogs should not be left alone for more than four hours, and your vet can advise how long suits your dog.
SPCA New ZealandPuppies under 6 months: no more than 2 to 3 hours during the day without a toilet and play break. Trained adults: about three hours. Never all day while you work.
Humane World for Animals, formerly the Humane Society of the United StatesPuppies under 6 months: no more than three or four hours at a time, because they cannot control their bladders or bowels for that long. The same page's FAQ also says no longer than the puppy's age in months plus one hour, and no more than 4 to 5 hours during the day for an adult.
American Kennel ClubNo fixed figure. Never longer than the dog is comfortable with or can hold their bladder, and never if it causes stress or panic.
VCA Animal Hospitals (US)No crate limit as such. Its toilet training rule adds an hour of bladder control per month of age, so about 3 hours at 3 months.

Published crate time guidance, by source

Australia

RSPCA Australia's knowledgebase has no crate time guidance that we could find. The nearest published figures are SPCA New Zealand's: no more than 2 to 3 hours in the day for a puppy under 6 months, and about three hours for a trained adult.

United States

Humane World for Animals, formerly the Humane Society of the United States, says three or four hours at a time for a puppy under 6 months and no more than 4 to 5 hours during the day for an adult. The AKC gives no number: never longer than the dog is comfortable with or can hold their bladder.

United Kingdom

RSPCA UK, PDSA and Blue Cross all land on about three hours as the most, and RSPCA UK says never all day while you work. Dogs Trust gives no crate figure but says no dog should be left alone for more than four hours.

Canada

We could not reach a Canadian welfare body's crate guidance in this pass. The cautious reading of the figures that are published is about three hours for a trained adult and less for a young puppy.

New Zealand

SPCA New Zealand says puppies under 6 months should spend no more than 2 to 3 hours in a crate during the day without a toilet and play break, trained adults about three hours, and that it is never acceptable to shut a dog in a crate all day while you go to work.

Out for longer than the crate limit? Use a puppy proofed pen with a toilet area, or a sitter or dog walker. The AKC and Dogs Trust both suggest a playpen or gated area instead.

What not to do

Night time

Start with the crate in or next to your bedroom. Humane World for Animals says puppies often need to go out in the night and you want to hear them, Blue Cross recommends your bedroom at the beginning, and VCA suggests a second crate in the bedroom for sleeping. Once the puppy sleeps well, move the crate gradually to where you want it. Blue Cross says inch by inch.

Last toilet trip, then into the crate with your usual cue and a treat. The AKC and the Royal Kennel Club both suggest a cover over a wire crate to make it darker and more like a den.

If the puppy cries, the advice differs. Humane World for Animals and SPCA New Zealand say try ignoring the whining for several minutes, then use your toilet phrase, and if the puppy gets excited take them out on a boring trip with no play. The AKC says never leave a dog to cry it out, and Blue Cross says leaving a new puppy alone to cry is stressful for them and suggests keeping them close and building up time apart gradually. A crate beside your bed lets you do both: you can respond calmly without letting the puppy out to play.

A playpen is an alternative. Dogs Trust says playpens can be more suitable than crates at night because they give more room to move, and a crate can sit inside or at one end of the pen as the bed.

Crates and separation distress

A crate does not treat separation anxiety. Humane World for Animals says it may stop destruction but the dog may get injured trying to escape, and that separation problems can only be resolved with counterconditioning and desensitisation. The AKC says dogs with separation anxiety often panic in a crate and may do better in a larger puppy proofed area such as a gated room or exercise pen. PDSA says crates should not be used to manage separation anxiety without professional guidance.

Choosing the crate

This is general guidance, your vet sets the actual schedule. Local disease risk, the products your clinic stocks and your puppy’s own history all change the plan. Take this page to your vet as a starting point, not as an instruction.

Common questions

How long can a puppy stay in a crate?

A few hours at most. SPCA New Zealand says no more than 2 to 3 hours in the day for a puppy under 6 months, PDSA and Blue Cross give three hours as the maximum for any dog, and Humane World for Animals says three or four hours for a puppy under 6 months. Never all day while you work.

Should I let my puppy cry in the crate at night?

The sources split. Humane World for Animals and SPCA New Zealand say ignore whining for several minutes, then offer a quiet toilet trip. The AKC says never leave a dog to cry it out, and Blue Cross says it is stressful for a new puppy. Keeping the crate beside your bed at first lets you respond calmly without turning night into play time.

Where should the crate go at night?

In or next to your bedroom at first, so you hear the puppy when they need the toilet. Humane World for Animals and Blue Cross both advise this. Once they sleep well, move the crate gradually to where you want it.

How long does crate training take?

Days to weeks, sometimes longer. PDSA says usually a few weeks at minimum, and Humane World for Animals says building to 30 calm minutes can take several days or weeks. Go at the puppy's pace and step back at any sign of worry.

Is crate training cruel?

Not when it is done gradually, the crate is the right size and it is never used for punishment or all day confinement. The AKC notes most dogs will be crated at some point, at the vet, boarding or in an emergency, so a dog that is relaxed in one copes better. Humane World for Animals adds that for some dogs a crate will not be an option.

Can I crate my puppy while I am at work?

Not for a full day. RSPCA UK and SPCA New Zealand both say it is never acceptable to shut a dog in a crate all day while you work. Use a puppy proofed pen with a toilet area, or a sitter or dog walker. Humane World for Animals suggests that if you will be away more than four or five hours a day, you consider whether this is the right time for a puppy.

Should there be water in the crate?

Yes, for anything more than a short stay. PDSA, Blue Cross and Dogs Trust all include water in the setup.

How we worked this out

Time limits disagree most. The UK charities, RSPCA UK, PDSA and Blue Cross, give about three hours as a maximum. SPCA New Zealand gives 2 to 3 hours for a puppy under 6 months and about three for an adult. Humane World for Animals gives three or four hours for a puppy under 6 months. The AKC and Dogs Trust give no crate figure at all and send owners to their own judgement or their vet. Puplr shows all of them in one table and does not average them.

Humane World for Animals contradicts itself. Its main text caps puppies under 6 months at three or four hours, while the frequently asked questions at the bottom of the same page say no longer than the puppy's age in months plus one hour, which would allow six hours at 5 months, and add a 4 to 5 hour daytime limit for adults. Both are quoted. The Puplr crate size calculator page lists the adult figure and the months plus one figure as untraced; as of 25 September 2026 both are on the Humane World for Animals page.

Crying at night is the other real split. Humane World for Animals and SPCA New Zealand say ignore whining for several minutes first. The AKC and Blue Cross say do not leave a puppy to cry it out. Both are shown, with the practical middle ground of a crate beside the bed.

The country differences come from who publishes what. The UK and New Zealand welfare bodies publish lower ceilings than the US ones. No crate time guidance was found in the RSPCA Australia knowledgebase, and the Ontario SPCA crate tips page returned an error, so no Australian or Canadian welfare body figure is given. Dogs Trust deliberately gives no crate number.

The step timings (about three minute sessions, 10 minutes after meals, 5 to 10 minutes sitting nearby, about 30 minutes before leaving the house, crating 5 to 20 minutes before departure) come from Humane World for Animals, SPCA New Zealand and RSPCA UK, which publish near identical four or five step methods.

Crate size figures are not repeated here. The crate size calculator has the measuring method and its own sources.
