Best Crate for a Large Breed Puppy: Size Guide + Top Picks

Choosing the best crate for a large breed puppy comes down to two decisions: most large breed puppies need a 42-inch wire crate with a divider panel — that covers dogs that will weigh 50–90 lbs as adults. Dogs expected to exceed 90 lbs at maturity (male Rottweilers, Great Danes, Cane Corsos, Mastiffs) need a 48-inch crate instead. The second decision is the divider: without it, a young puppy in an adult-sized crate will simply use the far end as a bathroom, which makes housetraining significantly harder.

If you're not sure how big your puppy will grow, our free puppy weight calculator generates a breed-specific adult weight estimate from your puppy's current weight and age — which tells you exactly which crate size you need before you buy anything.

What crate size does a large breed puppy actually need?

The right crate size is determined by your dog's projected adult weight and height — not their weight as an 8-week-old puppy. The standard sizing rule: a crate should be just large enough for your fully grown dog to stand up without hunching, turn around completely, and lie fully stretched out. Anything larger than that for a puppy in housetraining is counterproductive.

Here's how crate size maps to adult weight for the most popular large and giant breeds:

Breed	Adult weight (male)	Adult weight (female)	Recommended crate size
Labrador Retriever	65–80 lbs	55–70 lbs	42-inch
Golden Retriever	65–75 lbs	55–65 lbs	42-inch
German Shepherd	65–90 lbs	50–70 lbs	42-inch (48-inch for large males)
Australian Shepherd	50–65 lbs	40–55 lbs	42-inch
Siberian Husky	45–60 lbs	35–50 lbs	42-inch
Doberman Pinscher	75–100 lbs	60–90 lbs	42-inch (48-inch for large males)
Boxer	65–80 lbs	50–65 lbs	42-inch
Rottweiler	95–135 lbs	80–100 lbs	48-inch (males); 42-inch (most females)
Bernese Mountain Dog	80–115 lbs	70–95 lbs	48-inch
Cane Corso	99–110 lbs	85–99 lbs	48-inch
Great Dane	140–175 lbs	110–140 lbs	48-inch

If your breed isn't in this table, look up the breed's expected adult weight and match it to the sizing guide: 50–90 lbs → 42-inch; over 90 lbs → 48-inch. For mixed-breed puppies, our weight calculator can generate a projected adult weight estimate from your puppy's current size and age.

One source of confusion: breed terminology uses "large breed" to mean different things depending on the source. For crate sizing purposes, the practical cutoff is weight, not terminology. A Rottweiler may be called a large breed, but a 130-lb male Rottweiler needs a 48-inch crate regardless of how he's classified in breed standards.

Why you should buy the adult-sized crate from day one

Every few weeks, someone returns the medium crate they bought for their puppy and orders a larger one — sometimes twice. This replacement cycle costs more in total and doesn't solve the underlying problem any better than starting with the right size and using a divider. The single-crate approach is both cheaper and more effective for housetraining.

Here's what the growth data shows about why it works: based on veterinary growth data from Salt et al. (2017) — a PLOS ONE study analyzing over 8 million vet-measured weight records — a large breed puppy at 8 weeks has completed just 16.2% of their adult weight (male) or 17.5% (female). At 12 weeks, they're at 27.9% and 29.6% respectively. The full growth journey for a large breed dog doesn't complete until around 70 weeks (about 16 months). You can see how our growth predictions are built from this dataset if you want the full methodology.

A divider panel is what bridges the gap between puppy size and adult crate size. Set it so your puppy has just enough room to stand, turn, and lie flat — no spare room beyond that. As your puppy grows, you slide the divider back. As housetraining becomes reliable, you can eventually remove it entirely. One crate purchase, no upgrades, and the setup that actually makes housetraining work.

Without the divider, a puppy in a 42-inch or 48-inch crate will choose a corner to eliminate in and sleep in the other end. The denning instinct that crate training relies on — dogs avoiding soiling where they sleep — only functions when the space is snug enough that there is no available "other end." The divider doesn't add cost or complexity. Skip it and you make housetraining meaningfully harder.

The approach:

1. Buy a 42-inch wire crate with a divider panel (most quality wire crates include one at this size)
2. Start with the divider positioned so your puppy has room to stand, turn, and lie flat — nothing more
3. Move the divider back every 2–3 weeks as your puppy grows
4. Remove the divider entirely once your puppy is consistently housebroken

Divider guide: adjusting the crate as your large breed puppy grows

Large breed puppies grow fast in the first few months and slow gradually through their first year. The divider schedule below is based on the large breed growth curve from veterinary records (Salt et al., 2017), expressed as the percentage of adult weight your puppy has completed at each milestone age.

Weight estimates in the table below assume a male Lab or Golden at 70 lbs adult and a female at 60 lbs — adjust proportionally for heavier or lighter breeds in your crate. For your specific puppy's growth projection, use our weight calculator to see exactly where they sit on the curve at every age.

Age	% adult weight (male)	% adult weight (female)	Approx. weight (70-lb male)	Divider position in 42" crate
8 weeks	16.2%	17.5%	~11 lbs	~18–20 inches from back
12 weeks	27.9%	29.6%	~20 lbs	~22–24 inches from back
16 weeks (4 months)	41.4%	43.4%	~29 lbs	~26–28 inches from back
20 weeks (5 months)	54.0%	55.7%	~38 lbs	~30–32 inches from back
24 weeks (6 months)	65.7%	67.1%	~46 lbs	~34–36 inches from back
36 weeks (9 months)	87.8%	87.5%	~62 lbs	Remove divider if reliably housebroken
52 weeks (12 months)	96.0%	95.9%	~67 lbs	Full crate space

A few things this data makes clear: at 6 months, your large breed puppy still has more than a third of their total growth ahead of them. At 9 months, they're close enough to adult size — and typically housebroken enough — that the divider can usually come out. At 12 months, they've completed 96.0% of adult weight but may continue filling out with muscle through 14–16 months.

Use behavior as your primary guide alongside these age markers. If your puppy is eliminating inside the crate and sleeping away from the spot, the space is still too large — push the divider forward regardless of age. If your puppy never eliminates inside and reliably signals to go out, you may be able to expand the space a step early. For the bladder control side of the equation, our guide on how long a puppy can hold its bladder by age covers exactly what to expect at each month of development.

Giant breeds: when to choose a 48-inch crate instead

The 42-inch crate covers most dogs that owners think of as "large breeds" — but a meaningful group of dogs people describe as large actually needs the next size up. The cutoff is adult weight: if your dog will mature past 90 lbs, go with a 48-inch crate from day one.

The breeds where owners most commonly undersize the crate:

Rottweilers: Female Rottweilers (80–100 lbs) can typically manage a 42-inch crate. Male Rottweilers (95–135 lbs) should have the 48-inch — they're a wide, heavy-chested breed, and a full-grown 130-lb male in a 42-inch crate is noticeably cramped.

Bernese Mountain Dogs: Males reach 80–115 lbs and females 70–95 lbs. The 48-inch is the right call for this breed across both sexes, particularly given the Berner's long, thick double coat — which adds significant apparent bulk beyond their underlying frame.

Cane Corsos: Males reach 99–110 lbs with a 25–27.5 inch shoulder height. The Cane Corso is a wide, blocky breed, and the 48-inch serves both sexes better than the 42-inch.

Great Danes: At 140–175 lbs (males) and 110–140 lbs (females), Great Danes are the extreme end. Both sexes need the 48-inch, and very large male Danes may feel somewhat cramped even there — verify the interior dimensions of any crate you're considering for a Dane.

Giant breeds also grow for significantly longer than large breeds. Based on veterinary growth data from Salt et al. (2017), giant breeds don't reach 99% of adult weight until around 100 weeks — about 23 months. Large breeds hit 99% at 70 weeks. That extended growth window means a giant breed puppy spends many more months in the divider phase, making the adult-crate-from-day-one approach even more economically sensible for owners of bigger dogs. For more on how giant breed growth timelines compare to large breeds, see our guide on when large and giant breed puppies stop growing.

Wire, plastic, or soft-sided: best crate type for large breed puppies

For almost every large breed puppy, a wire crate is the best choice. Here's why:

• Divider panels: Nearly every quality wire crate in the 42-inch and 48-inch size includes a removable divider — the feature the single-crate-from-day-one strategy depends on. Most plastic and soft crates in these sizes don't include dividers.
• Ventilation: Large breed dogs run warm during growth. Open wire panels allow airflow that enclosed plastic crates can't match, which matters especially for double-coated breeds and dogs in warmer climates.
• Visibility: Most large breeds are social dogs. Wire crates let puppies see and hear the household while resting, which reduces the anxiety and vocalization that comes from feeling isolated. A puppy that can see you from their crate settles significantly faster than one in a windowless box.
• Easy cleanup: Wire crates have a removable metal tray that slides out, rinses, and goes back in a minute. Accidents are inevitable during housetraining — the tray setup makes them a two-minute interruption rather than a project.
• Flat fold: Most 42-inch and 48-inch wire crates fold flat for storage, moving, or taking between rooms. Plastic crates in this size are permanent structures.

Plastic airline crates are a legitimate second option for large breeds that genuinely prefer a darker, more enclosed sleeping space. Some independent breeds — Siberian Huskies, for example — do settle better in the den-like feel of a plastic crate. The trade-offs: no divider panel (complicates the housetraining setup), less airflow, and significantly bulkier to store or move. If you go the plastic route, buy a size that matches your adult dog's dimensions and improvise a divider solution with a cardboard insert during the housetraining months.

Soft-sided crates are not appropriate for large breed puppies. A motivated large breed puppy can push through or tear mesh panels within days. Soft crates are also genuinely difficult to sanitize after housetraining accidents — fabric absorbs urine in a way that wire trays don't. Reserve soft crates for reliably housebroken adult dogs who need portable containment and don't chew.

How to measure your large breed puppy for a crate

Even with a clear size recommendation, knowing the measurement method helps you verify dimensions for a specific crate model or size an unfamiliar breed accurately.

Length

Have your dog stand on a flat surface. Measure from the tip of the nose to the base of the tail — not the tail tip, which can add 6–10 inches that don't need to fit inside the crate. Add 2–4 inches to that measurement. For a fully grown male Labrador (22.5–24.5 inches at the shoulder, roughly 27–31 inches nose-to-tail-base), this gives a minimum crate length of 29–35 inches. A 42-inch crate clears this by a comfortable margin.

Height

Have your dog sit with their head held naturally upright. Measure from the floor to the top of the head — not the ears on an erect-eared breed, which adds misleading height. Add 2–4 inches. A male German Shepherd at 24–26 inches at the shoulder has a sitting height of approximately 28–32 inches. Most 42-inch wire crates are 28–30 inches tall internally — right at the minimum for tall large breeds. For German Shepherd males at the upper end of the height range, verify the interior height of your specific crate model.

One important note: you're measuring for the dog your puppy will become, not the puppy you have now. An 8-week-old large breed puppy at 16.2% of adult weight looks nothing like a 70-lb adult. Use the breed table above or run our weight calculator to get a breed-specific adult weight estimate, then apply the measurement guidelines to that projected adult size.

Setting up a large breed puppy's crate for success

Getting the right crate and right size is step one. Setting it up well is what makes it actually work as a housetraining tool.

Keep bedding thin for young puppies. An 8-week-old large breed puppy will chew a thick foam bed and soil it during housetraining. A thin, washable flat mat works better until your puppy is reliable. Many owners upgrade to a proper bolster or orthopedic bed around 5–6 months once accidents inside are rare.

Cover three sides with a lightweight blanket if your puppy seems anxious or overstimulated in the wire crate. The visual enclosure creates a den feeling without blocking airflow. Leave the door side uncovered so your puppy can still see the room. Remove the blanket immediately if your puppy pulls it in and starts chewing.

Place the crate where the family is. Large breed puppies that can see and hear the family settle into crate routines much faster than puppies kept in isolated rooms. Bedroom at night, main living area during the day is the standard placement. Being physically close without direct contact is the right balance, especially in the first two weeks.

Feed meals inside the crate. Moving meal placement from the crate door to just inside to the back over the first few days builds a positive association faster than most other approaches. A puppy that willingly walks into the crate for meals will generalize that feeling to going in on cue much faster.

Don't use the crate as punishment. The crate should remain a neutral-to-positive space throughout housetraining. Sending a puppy to the crate as a consequence for bad behavior makes them reluctant to enter voluntarily — which creates resistance right when you need willing crate acceptance most.

For a complete schedule covering overnight and daytime crate use at each age, our puppy crate schedule by age gives you a full framework from 8 weeks through 6 months. If your large breed puppy is whining overnight despite the right size and setup, our guide on puppy whining in the crate at night covers what actually helps — it's almost always an environmental adjustment issue rather than a crate sizing problem.

Breed-specific crate guides for popular large breeds

If you have one of the two most popular large breeds in the country, we've put together detailed guides with breed-specific divider schedules and growth-curve data:

• What size crate for a Lab puppy? — covers male and female Lab sizing, with a divider schedule based on Lab growth data
• What size crate for a Golden Retriever? — covers male and female Golden sizing, including how female Goldens compare to males on the growth curve

Both Labs and Goldens are solidly in the 42-inch category regardless of sex — male Labs reach 65–80 lbs and female Labs 55–70 lbs; male Goldens reach 65–75 lbs and female Goldens 55–65 lbs. The breed-specific posts include divider schedules calculated from each breed's actual growth trajectory rather than a generic large-breed average, which can be useful if you want precision timing on divider adjustments.

Best crate for a large breed puppy: FAQ

What size crate does a large breed puppy need?

Most large breed puppies need a 42-inch crate — this covers dogs that will weigh 50–90 lbs as adults, including Labs, Goldens, German Shepherds, Boxers, and Huskies. If your puppy will exceed 90 lbs at full growth (Rottweiler males, Great Danes, Mastiffs, Cane Corsos), size up to a 48-inch crate from day one. When in doubt, buy the larger size so you won't need to upgrade mid-puppyhood.

Should I get a 42-inch or 48-inch crate for my large breed puppy?

Dogs that will mature at 50–90 lbs need a 42-inch crate. Dogs that will exceed 90 lbs — including male Rottweilers (95–135 lbs), Great Danes (140–175 lbs), and Cane Corsos (99–110 lbs) — need a 48-inch crate. Use your breed's expected adult weight as the guide, and check our puppy weight calculator if you're unsure where your puppy will land.

Can I use a divider in a large breed puppy crate?

Yes — it's the recommended approach for every large breed puppy. Buy the adult-sized crate from day one and use the divider to keep the space snug during housetraining. At 8 weeks, a large breed puppy is only at 16.2% of adult weight based on veterinary growth data from Salt et al. (2017). The divider prevents a puppy from treating the far end of the crate as a bathroom, which is essential for housetraining to work the way it's supposed to.

When can I remove the divider from my large breed puppy's crate?

Remove the divider once your large breed puppy is reliably housebroken — typically around 6–9 months. By 9 months (36 weeks), large breed puppies are at roughly 87.8% of adult weight and most have reliable enough bladder control that the full crate space is appropriate. Use behavior as your primary signal: if there are no accidents inside the crate, the divider can come out. If accidents are still happening, keep the divider in regardless of age.

What is the best type of crate for a large breed puppy?

Wire crates are the best choice for most large breed puppies. They include divider panels, offer ventilation that large dogs need, let puppies see the household (which reduces anxiety), and are easy to clean after accidents. Plastic airline crates are a solid alternative for dogs that prefer an enclosed space. Soft-sided crates are not suitable for large breed puppies — the panels don't hold up to pushing and chewing, and the fabric is difficult to clean thoroughly after accidents.

Can a crate be too big for a large breed puppy?

Yes — for puppies in housetraining. A crate that is too large gives a puppy room to eliminate in one corner and sleep in another, which defeats the denning instinct that makes crate training work. A divider panel keeps the space appropriately snug during housetraining, which encourages the puppy to signal that they need to go outside rather than use a spare corner. Expand the space gradually as your puppy gains reliable bladder control over the months ahead.

Your large breed puppy will spend a significant amount of time in their crate during the first year — getting the size and setup right from the start makes that time work for housetraining rather than against it.
