Best Dog Houses for Big Dogs: 12 Breeds That Need the Most Space
Discover which big dog breeds need the largest dog houses. Compare 12 giant breeds on size, space needs, and outdoor tolerance to pick the right fit.
Why the Right Dog House Size Matters for Large Breeds
A dog house isn't just a shelter — it's a microclimate. For large and giant breeds, getting the dimensions wrong means your dog either can't fit inside comfortably or loses body heat trying to warm an oversized interior. The American Kennel Club recommends a dog house that allows your dog to stand up, turn around, and lie down without touching the walls, while still being snug enough to trap body heat in cold weather.
But "big dog" covers a massive range. A 70-pound Labrador needs a fundamentally different structure than a 150-pound Great Dane. This guide matches 12 popular large and giant breeds to their ideal dog house specifications so you can shop or build with confidence.
We included breeds that meet ALL of the following thresholds:
- Adult weight: 70+ lb (32+ kg) at maturity
- Adult height: 22+ inches (56+ cm) at the shoulder
- Outdoor tolerance: Breeds that can reasonably spend extended time outdoors with proper shelter (excludes brachycephalic breeds and those with extreme cold/heat sensitivity)
- AKC recognition: Fully recognized breeds with established size standards
Breeds are grouped into two tiers: Large (70–110 lb) and Giant (110+ lb). Within each tier, breeds are ordered by typical male weight, heaviest first.
12 Big Dog Breeds Ranked by Dog House Space Requirements
Tier 1: Giant Breeds (110+ lb / 50+ kg)
These dogs need XL or custom-built dog houses. Standard "large" models from most retailers will not accommodate them. Budget for a house with minimum interior dimensions of 42" L × 30" W × 36" H, and expect to spend $300–$800+ for a quality insulated structure.
1. Great Dane
Size class: Giant (140–175 lb / 64–79 kg; 30–32" at shoulder)
Key house trait: Extreme height — needs the tallest interior clearance of any breed on this list.
A Great Dane standing fully upright can reach 35+ inches at the shoulder. Your dog house door opening must be at least 34" tall, and interior peak height should be 40"+ to allow comfortable standing and turning. Despite their size, Great Danes are relatively low-energy indoors and often prefer being close to their people, so outdoor housing should supplement — not replace — indoor access.
Why this breed made the list: At 140–175 lb, Great Danes are among the tallest dogs alive. Standard XL dog houses max out around 32" interior height, making custom or specialty builds nearly mandatory.
2. Saint Bernard
Size class: Giant (140–180 lb / 64–82 kg; 28–30" at shoulder)
Key house trait: Massive bulk and thick double coat — needs wide entry and excellent ventilation.
Saint Bernards carry enormous body mass through a broad chest and heavy bone structure. A door width of 20"+ is essential. Their dense double coat means they overheat easily in warm weather, so summer ventilation (ridge vents, raised floors, or open-side designs with windbreaks) is more important than heavy insulation in moderate climates.
Why this breed made the list: The combination of 180 lb bulk and cold-weather heritage means they need a house that's wide, well-ventilated, and positioned in shade.
3. Newfoundland
Size class: Giant (130–150 lb / 59–68 kg; 27–29" at shoulder)
Key house trait: Water-loving breed — needs moisture-resistant materials and easy-clean flooring.
Newfoundlands will drag water, mud, and drool into any shelter. Cedar or marine-grade plywood interiors resist moisture damage better than particle board or untreated pine. A sloped floor with drainage or a raised plastic floor insert simplifies cleanup. Their heavy shedding also means interior corners should be smooth for easy hair removal.
Why this breed made the list: Their waterproof double coat and love of water make material selection as important as dimensions.
4. Leonberger
Size class: Giant (120–170 lb / 54–77 kg; 28–31.5" at shoulder)
Key house trait: Large frame with moderate cold tolerance — benefits from insulated walls without excessive interior volume.
Leonbergers have a water-resistant outer coat and thick undercoat, giving them decent cold tolerance. However, their long legs and deep chest mean they need length more than width — aim for 44"+ interior length. An offset door (positioned to one side rather than centered) creates a windbreak corner inside where the dog can curl up away from drafts.
Why this breed made the list: Their rectangular build and working-dog heritage make them genuine outdoor shelter users when properly acclimated.
5. Tibetan Mastiff
Size class: Giant (90–150 lb / 41–68 kg; 26–30" at shoulder)
Key house trait: Extreme cold hardiness — minimal heating needs but requires heavy-duty construction.
Tibetan Mastiffs evolved in Himalayan conditions and tolerate cold better than almost any breed. The priority here isn't insulation — it's structural durability. These powerful dogs can crush flimsy plastic houses. Rotomolded polyethylene or framed lumber construction with metal-reinforced corners holds up best. Males at 150 lb need a 40"+ long interior.
Why this breed made the list: Their guardian instincts keep them outdoors by choice, and their sheer power demands industrial-grade shelter materials.
6. Caucasian Shepherd (Ovcharka)
Size class: Giant (110–170 lb / 50–77 kg; 27–30" at shoulder)
Key house trait: Livestock guardian breed that lives outdoors full-time — needs year-round, all-weather housing.
This is one of the few breeds where a dog house serves as primary shelter rather than supplemental cover. Invest in a fully insulated, raised-floor house with a covered porch or vestibule area. The entry should face away from prevailing winds. In summer, a second open-air shade structure nearby prevents overheating since these dogs won't abandon their territory to seek cooler ground.
Why this breed made the list: As full-time outdoor guardians, they represent the highest-stakes dog house investment on this list.
Tier 2: Large Breeds (70–110 lb / 32–50 kg)
These breeds fit most commercially available XL dog houses, though you should still verify interior dimensions before purchasing. Expect to spend $150–$400 for a quality insulated model.
7. Rottweiler
Size class: Large (95–135 lb / 43–61 kg; 24–27" at shoulder)
Key house trait: Stocky, muscular build — needs a wider-than-average door opening.
Rottweilers carry their weight in a broad chest and thick neck. A 16–18" wide door is essential even though their height is moderate. Their short double coat provides moderate cold protection but they'll need a heated pad or extra bedding below 20°F (-7°C). Dark-colored houses can help absorb solar warmth in winter.
Why this breed made the list: Their width-to-height ratio is unusual — many standard "large" houses are tall enough but too narrow for a Rottie's shoulders.
8. German Shepherd
Size class: Large (65–90 lb / 29–41 kg; 24–26" at shoulder)
Key house trait: Highly adaptable — standard XL houses work well, but placement and training matter more.
German Shepherds are versatile enough to use most well-sized commercial dog houses. The bigger challenge is getting them to actually use it — their strong pack drive means they'd rather be at your door than in any shelter. Place the house within sight of your home's entry and use positive reinforcement (treats, praise, favorite blanket inside) to build a positive association.
Why this breed made the list: At 90 lb with a 26" shoulder height, they're right at the upper edge of "standard large" house sizing.
9. Bernese Mountain Dog
Size class: Large (85–115 lb / 39–52 kg; 25–27.5" at shoulder)
Key house trait: Cold-climate breed that overheats easily — ventilation and shade trump insulation.
Berners were built for Swiss alpine work and thrive in cold weather. In warm climates, their dog house must prioritize airflow: consider a raised design with mesh ventilation panels or a three-sided shelter rather than an enclosed box. A ceiling fan rated for outdoor use inside a larger shelter can make a meaningful difference during summer months.
Why this breed made the list: Their temperature sensitivity means the wrong house design can be dangerous in summer heat.
10. Alaskan Malamute
Size class: Large (75–100 lb / 34–45 kg; 24–26" at shoulder)
Key house trait: Arctic breed with extreme cold tolerance — simple, sturdy construction beats high-tech insulation.
Malamutes laugh at sub-zero temperatures. Their double coat provides insulation that rivals most manufactured dog houses. What they need is wind protection and a dry, elevated sleeping surface. A simple three-sided shelter with straw bedding (changed weekly) often outperforms an expensive heated house. The bigger risk is summer — ensure shade access and never confine a Malamute to an unventilated house in warm weather.
Why this breed made the list: Their cold tolerance is so extreme that overspending on insulation is the most common owner mistake.
11. Labrador Retriever
Size class: Large (65–80 lb / 29–36 kg; 22.5–24.5" at shoulder)
Key house trait: Most versatile breed on the list — standard XL commercial houses work well with minor modifications.
Labs fit comfortably in most "XL" or "large" dog houses from major manufacturers like Petmate, Precision Pet, or Suncast. Their water-resistant double coat handles rain and moderate cold well. The main consideration is chewing — young Labs will destroy foam insulation, plastic door flaps, and soft bedding. Choose houses with chew-resistant edges or wait until your Lab passes the 2-year mark before investing in a premium model.
Why this breed made the list: As the most popular dog breed in the US, Labs represent the most common "big dog house" buyer — and the most common sizing mistakes.
12. Anatolian Shepherd
Size class: Large (100–150 lb / 45–68 kg; 27–29" at shoulder)
Key house trait: Independent guardian breed — house placement matters more than house design.
Anatolian Shepherds patrol territory rather than nesting in one spot. They'll use a dog house sporadically, preferring elevated vantage points. Place the house on high ground with clear sightlines in all directions. A flat roof they can climb onto (with a ramp or steps for safe access) serves double duty as a lookout platform and shade source.
Why this breed made the list: Their 150 lb frame and guardian temperament mean they need a house designed around behavior, not just body measurements.

How to Choose Between the Top 3 Breeds for Your Situation
If you're deciding between a Great Dane, Saint Bernard, or Newfoundland — the three breeds with the most demanding dog house requirements — use this decision framework to narrow your choice based on your property, climate, and lifestyle.
Decision Flowchart: Which Giant Breed Fits Your Setup?
- Do you live in a climate where summer highs exceed 85°F (29°C)?
- YES → Great Dane (short coat dissipates heat better; indoor-dominant lifestyle reduces outdoor shelter dependency) or invest heavily in shade structures and cooling mats for any breed.
- NO → Continue to step 2.
- Will your dog have regular access to water (pond, pool, lake)?
- YES → Newfoundland (natural swimmer; water-resistant coat dries quickly; moisture-tolerant house materials align with wet lifestyle).
- NO → Continue to step 3.
- Do you need a dog that can spend 6+ hours outdoors unsupervised in cold weather?
- YES → Saint Bernard (dense double coat and alpine heritage provide the best cold-weather endurance of the three).
- NO → Any of the three will work; prioritize your preference for temperament and grooming commitment.
Honorable Mentions and Breeds to Avoid for Outdoor Housing
Honorable Mentions
These breeds narrowly missed the main list but deserve consideration depending on your needs:
- Irish Wolfhound (120–150 lb): Similar height to Great Danes but leaner build. Needs tall houses but narrower door openings work. Their shorter lifespan (6–8 years) means the dog house investment is shorter-term.
- English Mastiff (160–230 lb): Heaviest breed on the planet, but extremely low outdoor tolerance due to brachycephalic features and heat sensitivity. Include them only if you live in a cool climate and the house is supplemental to indoor living.
- Chesapeake Bay Retriever (65–80 lb): Slightly under our weight threshold, but their oily, water-repellent coat and working-dog toughness make them exceptional outdoor shelter users in wet climates.
Breeds to Avoid for Extended Outdoor Housing
These large breeds should NOT be primary outdoor house dwellers, regardless of house quality:
- Dogue de Bordeaux (110–150 lb): Brachycephalic airway syndrome makes temperature regulation unreliable. The AVMA warns that brachycephalic breeds are at elevated risk for heat stroke even in moderate temperatures.
- Neapolitan Mastiff (130–150 lb): Extreme skin folds trap moisture and heat. Extended outdoor confinement in a dog house creates skin infection risk.
- Bullmastiff (110–130 lb): Short coat, brachycephalic tendencies, and strong human attachment make them poor candidates for outdoor-only setups.
Dog House Sizing Formula: Get the Right Fit Every Time
Rather than guessing, use this formula recommended by canine housing specialists to calculate minimum interior dimensions for any breed:
- Interior Length = Dog's nose-to-base-of-tail measurement × 1.25
- Interior Width = Dog's shoulder width × 1.5
- Interior Height = Dog's height at shoulder × 1.25 (add 10% for breeds with erect ears)
- Door Height = Dog's shoulder height × 0.9 (the dog should duck slightly to enter — this traps warm air inside)
- Door Width = Dog's shoulder width × 1.1
For a 150 lb Great Dane measuring 32" at the shoulder with a 38" body length, that gives you: 47.5" long × 30"+ wide × 40" tall interior, with a 29" door height. Round up to standard lumber dimensions when building.
Frequently Asked Questions
What is the best dog house for big dogs that stay outdoors year-round?
For full-time outdoor dogs, prioritize: (1) raised floor at least 4" off the ground to prevent moisture wicking and pest entry, (2) insulated walls with R-value of 5+ for cold climates, (3) an offset doorway with a flexible wind flap, and (4) a removable roof or large access panel for cleaning. The K&H Pet Products Extra Large Outdoor Heated Dog House ($280–$350) and the Precision Pet Products Snoozzzz ($220–$280) are two commercially available models that meet these criteria for breeds up to 120 lb. For giant breeds above that weight, custom-built wooden houses from local carpenters or specialty builders like Doggy Dens typically run $600–$1,200.
Can two big dogs share one dog house?
Yes, but only if they're bonded and the house is sized for both. Add 25% to the length and width calculations beyond what a single dog needs. Two 80 lb Labs sharing a house need roughly a 44" × 32" interior rather than the 36" × 26" a single Lab requires. Never force unrelated dogs to share — resource guarding over shelter space is a common trigger for fights.
How much does a dog house for a giant breed cost?
Budget realistically: basic plastic shells for large breeds run $100–$200, insulated wooden houses for giant breeds range $300–$700, and custom-built or heated models with porches can exceed $1,000. Factor in $50–$100 annually for bedding replacement, cleaning supplies, and minor repairs. A well-built cedar or redwood house should last 8–12 years with basic maintenance.
Should I heat my big dog's house in winter?
It depends on the breed and your climate. Arctic and alpine breeds (Malamutes, Tibetan Mastiffs, Saint Bernards) generally don't need supplemental heat above -10°F (-23°C) if they have dry bedding and a windproof shelter. Short-coated breeds (Great Danes, Rottweilers) benefit from a heated pad (K&H Lectro-Soft, $40–$60) when temperatures drop below 20°F (-7°C). Never use heat lamps or space heaters — they're fire hazards in enclosed wooden structures.
Why won't my dog use the dog house I bought?
The three most common reasons: (1) The house is too large — dogs seek cozy, enclosed spaces, not cavernous rooms. If your 80 lb Lab is in a house sized for a Great Dane, she won't feel secure. (2) Placement is wrong — dogs won't use a house that blocks their view of the home or family activity. (3) Negative association — if the house was used as punishment or confinement during training, your dog avoids it. Rebuild positive associations by feeding meals near (then inside) the house and placing high-value treats inside. Use only positive reinforcement — never force or push your dog into the shelter.
