Bernese Mountain Dog Weight & Growth Chart
Complete weight guide with growth charts for male and female Bernese Mountain Dogs from puppy to adult.
Bernese Mountain Dog Weight Overview
The Bernese Mountain Dog weighs 70–115 lbs at maturity. Males (70–115 lbs) are typically heavier than females (59–101 lbs).
Males weigh 80-115 pounds, females 70-95 pounds; a sturdy, well-muscled body is ideal, and excess weight puts additional strain on already vulnerable joints.. The growth chart below shows the typical weight progression from puppyhood to adulthood.

When Does a Bernese Mountain Dog Stop Growing?
Most Bernese Mountain Dogs reach adult height of 23–27 inches by 15–24 months, with full body weight of 70–115 lbs achieved shortly after. Males fill out to 115 lbs while females reach 101 lbs.
Growth rate is influenced by genetics, diet quality, and spay/neuter timing. Moderate exercise needs of 30-60 minutes daily; enjoys hiking and carting activities but is heat-sensitive and should not be over-exercised in warm weather..
Bernese Mountain Dog Male vs Female Size Differences
Male and female Bernese Mountain Dogs differ noticeably in size, a pattern common in giant breeds. Males typically weigh 70–115 lbs, while females weigh 59–101 lbs. Both sexes stand 23–27 inches tall at the shoulder, though males tend to fall at the upper end of this range.
These size differences can influence practical ownership decisions. Larger males require more food, larger crate sizes, and stronger leash handling. Female Bernese Mountain Dogs at the lower weight range may be easier to manage physically for smaller handlers or families with children. Both sexes share the same temperament and health profile, so size preference should be a practical decision rather than a temperament-based one.
Is My Bernese Mountain Dog Overweight?
Assessing your Bernese Mountain Dog's body condition (healthy range: 70–115 lbs):
- Rib check: Run your hands along the ribcage—you should feel individual ribs under a slight fat layer
- Overhead view: A defined waist should be visible between ribs and hips
- Side profile: The abdomen should tuck upward behind the last rib
Overweight Bernese Mountain Dogs face higher risks of Histiocytic Sarcoma, joint problems, and shortened lifespan. As a giant-sized working breed, maintaining lean body condition is especially important for longevity. Work with your vet to adjust feeding and exercise if needed.
Bernese Mountain Dog Weight Management Tips
Maintaining your Bernese Mountain Dog at a healthy weight between 70 and 115 lbs is one of the most impactful things you can do for their long-term health. Studies consistently show that lean dogs live an average of 1.8–2.5 years longer than overweight dogs of the same breed.
Portion control: Use a measuring cup for every meal rather than estimating. Feed the amount recommended for your Bernese Mountain Dog's ideal weight, not their current weight if they are overweight. Divide daily food into two meals for adults and three meals for puppies under six months.
Treat management: Treats should not exceed 10% of daily caloric intake. Use small, low-calorie training treats and consider using pieces of your dog's regular kibble as rewards during training sessions. Avoid table scraps entirely, as they add unpredictable calories and can introduce foods that are toxic to dogs.
Exercise alignment: With an exercise needs rating of 3/5, the Bernese Mountain Dog requires moderate daily exercise. Balance food intake with activity level, adjusting portions during periods of reduced activity such as recovery from illness or injury.
Regular weigh-ins: Weigh your Bernese Mountain Dog monthly and track the trend. Gradual weight gain of even one to two pounds per month can lead to significant obesity over time. Your veterinarian can establish your dog's ideal weight during wellness visits and recommend caloric adjustments as needed.
Feeding Recommendation
Feed an adult Bernese Mountain Dog approximately 1.1–2.3 cups of quality kibble daily, split into two meals. Males (70–115 lbs) may need slightly more than females (59–101 lbs). Males weigh 80-115 pounds, females 70-95 pounds; a sturdy, well-muscled body is ideal, and excess weight puts additional strain on already vulnerable joints.. With moderate energy (3/5), portions at the middle of guidelines usually suffice.
Bernese Mountain Dog Weight by Age Table
The following table shows expected weight ranges for male and female Bernese Mountain Dogs at key developmental milestones. Individual dogs may fall slightly outside these ranges depending on genetics, nutrition, and activity level. Consult your veterinarian if your Bernese Mountain Dog's weight deviates significantly from these benchmarks.
| Age | Male (lbs) | Female (lbs) |
|---|---|---|
| 3 months | 20.7–25.3 | 17.6–21.5 |
| 6 months | 46.6–56.9 | 39.5–48.5 |
| 9 months | 67.3–82.2 | 57.1–70.0 |
| 12 months | 82.8–101.2 | 70.2–86.2 |
| 18 months | 98.3–120.2 | 83.4–102.3 |
| 24 months | 103.5–126.5 | 87.8–107.7 |
Health Risks of Incorrect Weight in Bernese Mountain Dogs
Both underweight and overweight conditions pose serious health risks for the Bernese Mountain Dog. Understanding these risks reinforces the importance of maintaining your dog within the 70–115 lb target range.
Overweight risks: Excess weight places additional strain on joints, increasing the risk and severity of conditions like Histiocytic Sarcoma. Overweight Bernese Mountain Dogs also face higher rates of diabetes, heart disease, respiratory compromise, heat intolerance, and reduced lifespan. Even moderate excess weight, just 10–15% above ideal, shortens life expectancy and reduces quality of life.
Underweight risks: A Bernese Mountain Dog consistently below 70 lbs may be experiencing inadequate nutrition, parasitic infection, dental problems that prevent eating, or underlying illness. Underweight dogs have weakened immune systems, poor coat quality, reduced energy, and slower healing. If your Bernese Mountain Dog appears thin despite normal feeding, veterinary examination is essential to rule out medical causes.
