Saint Bernard and Labrador Mix: The Complete Breed Guide
Everything about the Saint Bernard and Labrador mix: size, temperament, coat types, health risks, costs, and whether this gentle giant suits your family.
The Saint Bernard and Labrador mix — sometimes called a Saint Labernard or Labernard — pairs two of the most beloved family dogs in the world into one very large, very affectionate companion. This designer cross blends the mellow, watchful nature of the Saint Bernard with the exuberant, people-pleasing drive of the Labrador Retriever. The result is a dog that can weigh anywhere from 60 to 180 pounds, shed prodigiously, and melt into your couch like a giant, drooling lap dog.
But because mixed-breed dogs inherit traits unpredictably, no two Saint Bernard and Labrador mix puppies turn out exactly alike. This guide breaks down what you can reasonably expect — and where surprises are likely — so you can decide if this oversized sweetheart is the right fit for your household.
Parent Breed Breakdown: Saint Bernard Meets Labrador Retriever
Understanding the parent breeds is the single best way to anticipate what a Saint Bernard and Labrador mix puppy might become. Both breeds rank among the most popular family dogs in the United States, but they bring very different histories and physical traits to the table.
| Trait | Saint Bernard (AKC Working Group) | Labrador Retriever (AKC Sporting Group) |
|---|---|---|
| Weight Range | 120–180 lb / 54–82 kg | 55–80 lb / 25–36 kg |
| Height | 26–30 in / 66–76 cm | 21.5–24.5 in / 55–62 cm |
| Lifespan | 8–10 years | 11–13 years |
| Coat | Short smooth or long rough; dense undercoat | Short, dense double coat |
| Energy Level | Low to moderate | High |
| Original Purpose | Alpine rescue, draft work | Waterfowl retrieving, gundog |
| Temperament | Calm, gentle, watchful, somewhat stubborn | Outgoing, eager, trainable, mouthy |
| Shedding | Heavy, seasonal blowouts | Heavy, year-round with seasonal peaks |
The AKC Saint Bernard standard describes a dog bred for endurance in extreme cold, with a broad chest and powerful build. The AKC Labrador Retriever standard describes an athletic, water-resistant-coated gundog built for hours of swimming and retrieving. When you cross these two, you're essentially blending a mountain draft animal with an endurance swimmer — and the offspring can lean heavily toward either parent.
How Big Will a Saint Bernard and Labrador Mix Get?
This is one of the most common questions prospective owners ask, and the honest answer is: the size range is enormous. Because the Saint Bernard can be more than twice the weight of a Labrador, the resulting puppies span a very wide spectrum.
| Size Category | Weight | Height at Shoulder | Likely Inheritance Pattern |
|---|---|---|---|
| Smaller End | 60–90 lb / 27–41 kg | 22–25 in / 56–64 cm | More Labrador-dominant genes |
| Average | 90–130 lb / 41–59 kg | 25–28 in / 64–71 cm | Roughly equal parent influence |
| Larger End | 130–170+ lb / 59–77+ kg | 28–31 in / 71–79 cm | More Saint Bernard-dominant genes |
Most Saint Bernard and Labrador mix dogs land in the 90–130 lb range as adults, but littermates can vary by 40 or more pounds. Males tend to be 15–30 lb heavier than females. If you're adopting a puppy, ask the breeder for the exact weights of both parents — this gives the best indicator, though it's still an estimate. Growth typically continues until 18–24 months for the larger specimens, so budget for a dog that may not reach full size until age two.
Coat Types, Colors, and the Shedding Reality
Neither parent breed is hypoallergenic or low-shedding, and the Saint Bernard and Labrador mix is no exception. Here's what you might see in a litter:
- Short, dense double coat (Labrador-dominant): Sleek, water-resistant outer coat with a thick undercoat. Sheds moderately year-round with heavy seasonal blowouts in spring and fall.
- Medium-length rough coat (Saint Bernard-dominant): Slightly wavy, longer fur around the neck, chest, legs, and tail. Requires more frequent brushing and sheds heavily.
- Intermediate coat: Slightly longer than a Lab's but not as full as a rough-coated Saint Bernard. This is the most common outcome in F1 litters.
Common colors include black, chocolate brown, yellow/golden, and various combinations with white markings inherited from the Saint Bernard side. Some puppies display the classic Saint Bernard red-and-white patterning, while others look nearly identical to a black or yellow Lab with slightly heavier bone structure.
Temperament: What to Expect from a Saint Bernard Lab Mix
Both parent breeds are known for being good-natured and people-oriented, which gives the Saint Bernard and Labrador mix a strong temperament foundation. But the expression of that temperament varies considerably between individual dogs.
Best-Case Scenario
You get a dog with the Labrador's trainability and enthusiasm combined with the Saint Bernard's calm steadiness. This dog greets visitors warmly, settles quickly indoors, learns commands readily, and is gentle with children. Think of a large, patient dog that enjoys a good walk but is equally content lounging at your feet.
Challenging Scenario
You get a dog with the Labrador's high energy and mouthiness paired with the Saint Bernard's stubbornness and size. This combination means a 120-lb dog that jumps on people, pulls hard on leash, counter-surfs, and doesn't always respond to the first command. It's not aggression — it's enthusiasm without brakes, in a very large package.
Common Temperament Traits
- Affectionate and clingy: Both breeds bond closely to their families. Expect a dog that follows you room to room and wants to be on or near you at all times.
- Good with children: Generally patient and tolerant, but the sheer size means toddlers can be knocked over accidentally. Always supervise interactions.
- Moderate watchdog instinct: The Saint Bernard side may bark at strangers approaching the home, but neither parent breed is a protection dog. This mix is more likely to lick an intruder than bite one.
- Food-motivated: Labs are notoriously food-driven, and Saint Bernards are no strangers to a meal. This mix tends to be highly treat-motivated (great for training) but also prone to counter-surfing, garbage-raiding, and obesity.
- Variable energy: Some individuals are couch potatoes; others need 60–90 minutes of daily exercise. You won't know which you'll get until the dog matures.
Generations Explained: F1, F1B, and Beyond
If you're researching breeders, you'll encounter generation terminology. Here's what it means for the Saint Bernard and Labrador mix:
F1B (First Generation Backcross): An F1 Saint Bernard/Lab mix bred back to one of the parent breeds (usually the Labrador). Results in puppies that lean more heavily toward the backcross breed.
F2 (Second Generation): Two F1 Saint Bernard/Lab mixes bred together. This produces the widest variation in a single litter — some puppies may look almost entirely like one parent breed while others look like a blend.
Multigen (F3+): Multiple generations of Saint Bernard/Lab mixes bred together. Extremely rare for this particular cross, as most breeders do not maintain dedicated multigen lines for non-doodle designer breeds.
Because the Saint Bernard and Labrador mix is not as commercialized as Labradoodles or Goldendoodles, the vast majority of available puppies are F1 crosses. This means you'll typically see a wide range of appearances and sizes even within a single litter. Ask breeders which generation they're producing and request to see both parent dogs in person.
Health Considerations: Hybrid Vigor vs. Reality
Let's address a persistent myth: mixed-breed dogs are not automatically healthier than purebreds. The concept of "hybrid vigor" (heterosis) suggests that crossing two genetically distinct populations reduces the expression of recessive inherited diseases. There is some truth to this — but it only applies to conditions where both parent breeds carry different recessive mutations. When both breeds share the same genetic vulnerability, the mix inherits that risk equally.
The Saint Bernard and the Labrador Retriever share several overlapping health concerns, and a responsible owner should be aware of all of them.
| Condition | Prevalence | Shared by Both Breeds? | Screening Test |
|---|---|---|---|
| Hip Dysplasia | Saint Bernard: ~47% affected (OFA data); Lab: ~12% | Yes | OFA or PennHIP radiographs |
| Elbow Dysplasia | Saint Bernard: ~22%; Lab: ~12% | Yes | OFA elbow radiographs |
| Gastric Dilatation-Volvulus (Bloat) | High risk in deep-chested large breeds | Yes | No screening; preventive gastropexy discussed with vet |
| Dilated Cardiomyopathy (DCM) | Saint Bernard: elevated risk | Partial (more common in Saints) | Echocardiogram, cardiac exam |
| Osteosarcoma | Saint Bernard: significantly elevated | Partial (more common in Saints) | No routine screening; monitor for lameness |
| Exercise-Induced Collapse (EIC) | Labrador: ~5–10% carriers | No (Lab-specific) | DNA test for EIC gene |
| Obesity | Labrador: highest breed predisposition | Yes (both prone) | Body condition scoring at every vet visit |
According to the Merck Veterinary Manual, hip dysplasia is the most common inherited orthopedic condition in large-breed dogs, and both parent breeds are predisposed. A Saint Bernard and Labrador mix should be evaluated by a veterinarian at 4 months, 12 months, and 24 months for joint health. PennHIP screening can be performed as early as 16 weeks.
Bloat (GDV) is a life-threatening emergency. Both parent breeds are deep-chested and at elevated risk. Know the signs: a distended abdomen, unproductive retching, restlessness, and rapid collapse. If you see these symptoms, go to an emergency vet immediately — bloat is fatal without surgical intervention. Many owners of giant-breed dogs discuss prophylactic gastropexy (stomach tacking) with their veterinarian at the time of spay or neuter.
- Sudden abdominal swelling or retching without vomiting
- Rear leg weakness, dragging, or sudden lameness (possible joint or bone cancer concern)
- Difficulty breathing, excessive panting at rest, or blue-tinged gums
- Seizure activity or sudden collapse
- Inability to stand or bear weight on any limb
Lifespan Expectations
The Saint Bernard's typical lifespan is 8–10 years, while the Labrador's is 11–13 years. Most Saint Bernard and Labrador mixes live approximately 9–12 years, with those leaning toward the Labrador end of the size spectrum tending to live slightly longer. Larger individuals face the same accelerated aging and joint wear that shortens giant-breed lifespans.
Grooming and Daily Care Requirements
Care needs depend heavily on which coat type your dog inherits, but plan for a moderate-to-high grooming commitment regardless.
Grooming Schedule
- Brushing: 2–3 times per week minimum with a slicker brush and undercoat rake. Daily during spring and fall shedding seasons.
- Bathing: Every 6–8 weeks, or as needed. A dog this size may require a professional groomer with a large-breed tub, or a walk-in shower at home. Expect to pay $60–$120 per professional bath for a dog over 100 lb.
- Nail trimming: Every 3–4 weeks. Large dogs that don't wear nails down on pavement may need more frequent trims. Overgrown nails alter gait and worsen joint problems.
- Ear cleaning: Weekly, especially if the dog inherits the Lab's floppy, pendant ears. Moisture trapped in floppy ears leads to yeast and bacterial infections.
- Dental care: Daily brushing ideal; at minimum, veterinary dental cleanings every 1–2 years under anesthesia.
- Drool management: If your mix inherits the Saint Bernard's loose flews (lip folds), keep a towel handy. Some individuals drool significantly after drinking or eating; others are relatively dry.
Exercise Needs
Plan for 45–75 minutes of daily exercise, adjusted to the individual dog's energy level. This should include:
- Two structured leash walks of 20–30 minutes each
- Off-leash play in a secure area if your dog has reliable recall
- Swimming if available — both parent breeds tend to enjoy water, and it's excellent low-impact exercise for large joints
- Mental stimulation through puzzle feeders, scent games, or training sessions
Avoid forced running or high-impact exercise (like jumping from heights or long runs on hard pavement) until growth plates close, typically around 18–24 months in giant breeds. Consult your veterinarian before starting any strenuous exercise program with a young large-breed dog.
Nutrition and Feeding Costs
A 100–140 lb dog eats approximately 4–6 cups of high-quality kibble per day, depending on activity level and the food's caloric density. Look for an AAFCO-approved large-breed formula with a guaranteed analysis showing minimum 22% protein and controlled calcium/phosphorus ratios for joint support. Expect to spend $80–$150 per month on food alone. Brands like Purina Pro Plan Large Breed, Royal Canin Giant, and Hill's Science Diet Large Breed are commonly recommended by veterinarians.
Cost Breakdown: What You'll Actually Spend
| Expense Category | Estimated Cost Range | Notes |
|---|---|---|
| Puppy Purchase (Breeder) | $800–$2,500 | Varies by breeder reputation, health testing, location |
| Adoption/Rescue Fee | $150–$500 | Often includes spay/neuter, initial vaccines, microchip |
| First-Year Veterinary Costs | $800–$1,800 | Puppy vaccines, spay/neuter, heartworm prevention, fecal tests |
| Annual Vet Costs (Adult) | $600–$1,200 | Wellness exams, vaccines, dental, preventive medications |
| Food (Annual) | $960–$1,800 | $80–$150/month depending on brand and dog size |
| Heartworm/Flea/Tick Prevention | $250–$500/year | Simparica Trio, NexGard, or similar — dose based on weight |
| Grooming (Professional) | $360–$720/year | $60–$120 per session, 6–8 times annually |
| Pet Insurance | $600–$1,200/year | Higher premiums for giant breeds; consider enrolling as a puppy |
| Emergency Fund Recommendation | $2,000–$5,000 | Bloat surgery alone can cost $3,000–$7,000 |
Because this is a less common designer cross, dedicated breeders are relatively scarce. Most Saint Bernard and Labrador mix puppies come from small-scale hobby breeders or occur as accidental litters. Check breed-specific rescues for both Saint Bernards and Labrador Retrievers — mixed-breed dogs from these breeds regularly end up in rescue, particularly when owners underestimate the adult size. Organizations like Saint Bernard Rescue Foundation and Labradors and Friends often list mixed-breed dogs.
Who Is the Saint Bernard and Labrador Mix Best Suited For?
This mix works best for households that meet several criteria:
- Space: A home with a fenced yard is strongly recommended. Apartments can work if the dog gets sufficient daily exercise, but a 120-lb dog in a studio is a challenging arrangement for everyone.
- Experience level: Intermediate to experienced dog owners. First-time owners can succeed with this mix, but the size and strength demand confident leash handling and consistent training from puppyhood.
- Family composition: Excellent with children when properly socialized, but families with toddlers should wait until kids are at least 5–6 years old to avoid accidental knockdowns. Good with other dogs when introduced properly; cat compatibility varies by individual prey drive.
- Climate: Better suited to cooler climates. Both parent breeds have dense double coats, and large dark-coated dogs overheat rapidly in hot, humid conditions. If you live in the South or Southwest, plan for indoor air conditioning and exercise during early mornings and evenings only.
- Budget: Everything costs more for a giant dog — food, medication (dosed by weight), veterinary procedures, grooming, crates, beds, and vehicle transport. Budget realistically for $3,000–$5,000+ in annual costs.
- Time commitment: This is a social dog that does not do well left alone for 10+ hours daily. Separation anxiety is possible, especially from the Labrador side, and a bored, anxious 130-lb dog can cause significant property damage.
Frequently Asked Questions
What two breeds make up the Saint Bernard and Labrador mix?
This cross combines a purebred Saint Bernard (a giant Alpine working breed originally used for mountain rescue in Switzerland) with a purebred Labrador Retriever (a medium-large sporting breed from Newfoundland, Canada, originally used for waterfowl retrieval). The resulting mix is sometimes informally called a Saint Labernard or Labernard.
Is the Saint Bernard and Labrador mix hypoallergenic?
No. Neither parent breed is hypoallergenic, and the mix inherits a double coat that sheds heavily year-round with intensified seasonal shedding in spring and fall. People with dog allergies are likely to react to this cross. If low-shedding is a priority, this is not the right mix for you.
How much does a Saint Bernard and Labrador mix puppy cost?
Expect to pay between $800 and $2,500 from a breeder, depending on health testing, location, and demand. Adoption through a breed rescue typically costs $150–$500. Because this is not a highly commercialized designer breed, prices are generally lower than for Labradoodles or Bernedoodles.
Are Saint Bernard and Labrador mixes good with kids?
Generally yes — both parent breeds are known for being gentle and patient with children. However, the mix's large size means small children can be accidentally knocked over during play. Always supervise interactions between any dog and children under 10, and teach children to respect the dog's space during meals and sleep.
Do Saint Bernard and Labrador mixes drool a lot?
It depends on which parent the dog takes after. Saint Bernard-type flews (loose upper lips) produce significant drooling, especially after eating, drinking, or exercise. Labrador-type lip structure produces minimal drool. You won't know until the puppy matures, but keep towels accessible just in case.
Can this mix live in an apartment?
It's possible but challenging. The dog needs 45–75 minutes of daily outdoor exercise regardless of living space. Larger individuals (130+ lb) will physically struggle with multiple flights of stairs and may be restricted by apartment breed/size policies. A house with a fenced yard is the ideal setup.
Whether you find your Saint Bernard and Labrador mix through a breeder or a rescue, prepare your home for a very large, very loving dog that will demand space, food, grooming attention, and a spot on your couch. With proper training, preventive veterinary care, and realistic expectations about the variability inherent in any mixed breed, this cross can be a wonderful family companion for 9–12 years of slobbery, loyal devotion.
