Bernese Mountain Dog Rottweiler Mix: Complete Breed Guide
Everything about the Bernese Mountain Dog Rottweiler mix — size, temperament, health risks, coat types, cost.
What Is a Bernese Mountain Dog Rottweiler Mix?
The Bernese Mountain Dog Rottweiler mix — sometimes called a "Bernese Rottie" or "Mountain Rottie" — is a large to giant-sized designer cross between two powerful working breeds: the Bernese Mountain Dog (Berner) and the Rottweiler. Both parent breeds originated in Europe as draft and herding dogs, which means this mix typically inherits substantial size, strength, and a working-dog drive.
This is not an AKC-recognized breed. It falls under the designer or mixed-breed category, meaning individual puppies can vary significantly in appearance, temperament, and health profile — even within the same litter. If you're researching this cross, understanding both parent breeds is essential to predicting what you might get.
Parent Breed Breakdown: Berner vs. Rottweiler
Before evaluating the mix, you need to understand what each parent brings to the table. These two breeds share some traits (loyalty, size, working heritage) but differ sharply in others (energy, grooming needs, lifespan).
| Trait | Bernese Mountain Dog | Rottweiler |
|---|---|---|
| AKC Group | Working | Working |
| Weight Range | 70–115 lb (32–52 kg) | 80–135 lb (36–61 kg) |
| Height | 23–27.5 in (58–70 cm) | 22–27 in (56–69 cm) |
| Coat | Long, silky, double coat; tricolor | Short, dense, double coat; black and tan |
| Shedding | Heavy (seasonal blowouts) | Moderate (year-round) |
| Energy Level | Moderate | Moderate to high |
| Trainability | Eager but sensitive | Intelligent, strong-willed |
| Lifespan | 6–8 years | 9–10 years |
| Guard Instinct | Low (alert but friendly) | High (natural guardian) |
| Origin | Swiss Alps — farm/draft dog | Germany — herding/guard dog |

Generations Explained: F1, F1B, and Multigen Crosses
- F1 (First Generation): One purebred Bernese Mountain Dog × one purebred Rottweiler. Maximum genetic diversity, but highest trait variability — puppies in the same litter can look and behave very differently.
- F1B (First Generation Backcross): An F1 Bernese Rottie × one of the parent breeds (usually Berner for coat or Rottweiler for build). Slightly more predictable traits leaning toward the backcross parent.
- F2 (Second Generation): Two F1 Bernese Rotties bred together. Trait predictability does NOT improve — genetic recombination can produce wider variation than F1 litters.
- Multigen (F3+): Multiple generations of Bernese Rottie × Bernese Rottie breeding. Still not a stabilized breed; significant variation persists. No major kennel club recognizes this cross as a breed.
Most Bernese Mountain Dog Rottweiler mixes you'll find are F1 crosses — a deliberate pairing of two purebreds. Unlike Poodle-based designer breeds (Labradoodles, Goldendoodles), this mix hasn't developed a large multigen breeding community. That means you're almost always looking at first-generation puppies with highly individual outcomes.
Size, Build, and Appearance: What to Expect
This is a large to giant cross. Both parents are substantial working dogs, so the mix will not be small. Here's the realistic range based on parent breed standards:
| Measurement | Low End | High End |
|---|---|---|
| Adult Weight (female) | 70 lb (32 kg) | 105 lb (48 kg) |
| Adult Weight (male) | 85 lb (39 kg) | 130 lb (59 kg) |
| Height at Shoulder | 22 in (56 cm) | 27 in (69 cm) |
| Time to Full Size | 18 months | 24–30 months |
Giant-breed dogs grow slowly. Expect your Bernese Rottie to continue filling out through 2 to 2.5 years of age. During growth, feed a large-breed puppy formula (AAFCO-certified) to manage growth rate and reduce orthopedic risk. Brands like Purina Pro Plan Large Breed Puppy, Royal Canin Giant Puppy, or Hill's Science Diet Large Breed Puppy are formulated to control calcium-phosphorus ratios during skeletal development.
Coat Type Possibilities
Coat inheritance is one of the most variable traits in this cross:
- Short-to-medium coat (Rottweiler-leaning): Dense, flat-lying, with moderate year-round shedding. Easier to groom but not low-shedding.
- Long coat (Berner-leaning): Silky, potentially wavy, with heavy seasonal shedding. Requires brushing 3–4 times per week minimum.
- Intermediate coat: Medium-length with some feathering on legs and chest. Most common in F1 crosses.
Color is typically black with tan/rust markings, though tricolor (black, white, rust) appears when Berner coat genes express. White chest markings and blazes are possible but not guaranteed.
Temperament Range: Best Case and Challenging Scenarios
Temperament is where the unpredictability of mixed breeds matters most. Both parent breeds are loyal and intelligent, but they differ in key behavioral traits that can combine in unexpected ways.
- Calm, confident demeanor (Berner influence)
- Strong family bond without clinginess
- Alert and watchful without reactivity
- Good with children when properly socialized
- Trainable with positive reinforcement methods
- Stable around strangers after early exposure
- Strong guardian instinct with wariness of strangers (Rottweiler influence)
- Same-sex dog aggression (common in Rottweiler lines)
- Leash reactivity if under-socialized
- Stubbornness during training (both breeds can be willful)
- Prey drive toward smaller animals
- Separation anxiety if left alone excessively
The Rottweiler's guarding heritage is not something to take lightly. According to the AKC Rottweiler standard, the breed is "calm, confident, and courageous" with "a self-assured aloofness that does not lend itself to immediate and indiscriminate friendships." If your mix inherits strong guardian tendencies, early and extensive socialization (ideally starting at 8–16 weeks) is non-negotiable.
Positive reinforcement training — using treats, praise, and play rewards — works best for this cross. Force-free methods build trust with sensitive Berner-influenced dogs while maintaining clear boundaries for strong-willed Rottweiler-influenced ones. Avoid aversive tools like prong collars or shock collars, which can increase fear-based reactivity in guardian breeds.
Health Considerations: Hybrid Vigor Myth vs. Reality
One of the most persistent myths about designer crosses is hybrid vigor — the idea that mixed-breed dogs are automatically healthier than purebreds. Here's the reality: while genetic diversity can reduce the risk of certain recessive disorders, a cross between two large breeds that share overlapping health risks does not eliminate those risks. It may redistribute them.
Both the Bernese Mountain Dog and Rottweiler are predisposed to several serious conditions. Your mix could inherit any combination of these:
| Condition | Berner Risk | Rottweiler Risk | Mix Risk Level |
|---|---|---|---|
| Hip Dysplasia | High (~25% of breed) | High (~20% of breed) | High — both parents carry risk |
| Elbow Dysplasia | Moderate-High | Moderate | Moderate-High |
| Osteosarcoma (bone cancer) | High (leading cause of death) | High (leading cause of death) | High — shared risk |
| Histiocytic Sarcoma | High (breed-specific cancer) | Low | Moderate — possible inheritance |
| Gastric Dilatation-Volvulus (Bloat) | Moderate (deep-chested) | Moderate (deep-chested) | Moderate-High |
| Cardiomyopathy | Low-Moderate | Moderate (aortic stenosis) | Moderate |
| Cranial Cruciate Ligament (CCL) Tears | Moderate | High | Moderate-High |
According to the Merck Veterinary Manual, hip dysplasia has a strong hereditary component in large and giant breeds, and environmental factors (rapid growth, obesity, over-exercise in puppyhood) compound genetic risk.
Lifespan Reality
The Bernese Mountain Dog has one of the shortest lifespans of any breed — a median of just 6–8 years, largely due to high cancer rates. The Rottweiler averages 9–10 years. For the mix, a realistic lifespan expectation is 8–11 years, though individual outcomes vary. Some Bernese Rotties with favorable genetics and excellent care reach 12 years; others may face cancer or orthopedic disease earlier.
Ask your breeder for proof of these tests on both parent dogs:
- OFA or PennHIP hip evaluation (both parents)
- OFA elbow evaluation (both parents)
- Cardiac exam by a veterinary cardiologist
- OFA ophthalmologist evaluation
- Berner-specific: DNA test for histiocytic sarcoma markers (available through NC State University's canine genetics lab)
Consult your veterinarian about an appropriate screening schedule for your mixed-breed dog starting at 1 year of age.
Grooming, Exercise, and Daily Care
Grooming Based on Coat Type
Your grooming commitment depends entirely on which parent's coat your dog inherits:
- Short coat (Rottweiler type): Brush 1–2 times per week with a rubber curry brush or bristle brush. Bathe every 6–8 weeks or as needed. Expect moderate shedding year-round.
- Medium-to-long coat (Berner type): Brush 3–5 times per week with a slicker brush and undercoat rake. During seasonal shedding (spring and fall), daily brushing is necessary. Professional grooming every 8–12 weeks may help manage coat length.
- Nail trimming: Every 3–4 weeks regardless of coat type. Large breeds need shorter nails to protect joint health.
- Ear cleaning: Weekly checks; clean with a veterinary ear cleanser if debris accumulates (especially if ears are floppy/dropped).
Exercise Requirements
Plan for 60–90 minutes of structured exercise daily for an adult Bernese Rottie. This should include:
- Two 30-minute leash walks (minimum)
- Mental stimulation: puzzle feeders, nose work, obedience training sessions
- Low-impact activities preferred — swimming is excellent for joint health
- Avoid forced running or high-impact activities (jumping, agility) until growth plates close at 18–24 months
During puppyhood, follow the "5 minutes per month of age" guideline for structured walks: a 4-month-old puppy gets roughly 20 minutes of walk time per session, twice daily. Free play in a yard is fine in addition.
Cost, Availability, and Finding Your Dog
Purchase Price
Bernese Mountain Dog Rottweiler mixes are not as widely bred as Poodle-based designer dogs, which affects both availability and pricing:
| Source | Price Range | Notes |
|---|---|---|
| Responsible breeder (health-tested parents) | $1,200–$2,500 | Includes OFA certifications, first vaccines, health guarantee |
| Casual/backyard breeder | $500–$1,000 | Usually no health testing — higher long-term vet costs |
| Breed-specific rescue | $200–$500 | Check Berner or Rottweiler rescues — mixes occasionally appear |
| General shelter/rescue | $50–$300 | Uncommon but possible; may be labeled as "large mixed breed" |
First-Year Ownership Costs
Beyond purchase price, budget for these first-year expenses:
- Veterinary care (puppy series + spay/neuter): $800–$1,500
- Food (large-breed formula, 50–70 lb bags): $600–$1,000/year
- Supplies (crate, bed, harness, bowls, toys): $300–$600
- Training (puppy class + basic obedience): $200–$500
- Pet insurance (recommended for large breeds): $600–$1,200/year
- Total first-year estimate: $3,700–$7,300 (including dog purchase)
Pet insurance is strongly recommended for this cross. Given the shared cancer risk from both parent breeds and the high cost of orthopedic surgeries (TPLO for cruciate tears runs $3,500–$6,000 per knee), a comprehensive policy with a $250–$500 deductible can protect against catastrophic expenses. Companies like Trupanion, Healthy Paws, and Nationwide cover mixed breeds.
Who This Mix Suits Best
The Bernese Mountain Dog Rottweiler mix is not a beginner-friendly dog. Here's an honest assessment of who thrives with this cross:
- Experienced dog owners familiar with large guardian breeds
- Homes with fenced yards (minimum 5-foot fence)
- Active families who can commit to daily exercise
- Households without small dogs (same-sex aggression risk)
- Owners willing to invest in early socialization and ongoing training
- People prepared for a 90+ lb dog that may lean on you for affection
- First-time dog owners
- Apartment living without easy outdoor access
- Families with very young children (size + strength risk)
- Multi-dog homes with same-sex large dogs
- Owners who work 10+ hours away from home
- Anyone unwilling to commit to structured training
Frequently Asked Questions
What two breeds make up this mix?
The Bernese Mountain Dog Rottweiler mix is a cross between a purebred Bernese Mountain Dog (Swiss draft/farm dog) and a purebred Rottweiler (German herding/guardian breed). Both belong to the AKC Working Group.
How big will a Bernese Mountain Dog Rottweiler mix get?
Adults typically weigh 70–130 lb (32–59 kg) and stand 22–27 inches (56–69 cm) at the shoulder. Males tend toward the higher end. Full adult size is usually reached between 18 and 30 months of age.
What will the temperament be like?
Temperament varies significantly between individuals. Expect loyalty and intelligence from both parent breeds, but the balance between the Berner's gentle friendliness and the Rottweiler's guardian instinct is unpredictable. Early socialization (8–16 weeks) and consistent positive reinforcement training are essential regardless of which traits emerge.
Is this mix hypoallergenic or low-shedding?
No. Neither parent breed is hypoallergenic. The Bernese Mountain Dog is a heavy shedder with seasonal coat blowouts, and the Rottweiler sheds moderately year-round. A Bernese Rottie will shed regardless of which coat type it inherits. If you have dog allergies, this is not a suitable cross.
What health issues might this mix inherit?
Shared risks from both parent breeds include hip dysplasia, elbow dysplasia, osteosarcoma (bone cancer), and gastric dilatation-volvulus (bloat). Berner-specific risks include histiocytic sarcoma; Rottweiler-specific risks include aortic stenosis and cranial cruciate ligament tears. Consult your veterinarian about appropriate screening starting at 1 year of age.
How much does a Bernese Mountain Dog Rottweiler mix cost?
From a responsible breeder with health-tested parents, expect to pay $1,200–$2,500. Rescue adoption fees range from $50–$500. First-year total ownership costs (including purchase, veterinary care, food, supplies, and insurance) typically range from $3,700–$7,300.
Are Bernese Rotties good with children?
When properly socialized, they can be gentle and patient with children. However, their large size (up to 130 lb) means they can accidentally knock over small children. Always supervise interactions, and teach children appropriate behavior around dogs. This mix is best suited to families with children aged 8 and older.
Do Bernese Mountain Dog Rottweiler mixes need professional training?
Professional training is highly recommended, especially for owners without experience handling large guardian breeds. A certified positive-reinforcement trainer (look for CPDT-KA or KPA-CTP credentials) can help establish foundations during the critical 8–16 week socialization window and address any emerging behavioral challenges.
