Bernese Mountain Dog Weight & Growth Chart
Complete weight guide with growth charts for male and female Bernese Mountain Dogs from puppy to adult.
The Bernese Mountain Dog belongs to the Working group and originates from Switzerland. Adults typically weigh between 70 and 115 pounds, standing 23 to 27 inches at the shoulder. Life expectancy runs from 7 to 10 years, and the figures on this page describe that range rather than a single average, because the spread is what matters when you are deciding. Running costs settle around $218 a month once the dog is past puppyhood, before insurance and before anything unexpected. These numbers come from published breed standards and, where a standard is silent, from longevity and veterinary studies; they describe the breed as a population and not the dog in front of you. Line, upbringing, early socialisation and simple chance move an individual well away from the typical profile, and two dogs of the same breed often differ more than two dogs of different breeds. Nothing here is a diagnosis: for a specific animal, a veterinary surgeon who has examined it will always know more than a table.
Bernese Mountain Dog Weight Overview
Adult Bernese Mountain Dogs typically weigh between 70 and 115 pounds, with males generally being larger than females. Males average 70–115 lbs while females typically weigh 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..

When Does a Bernese Mountain Dog Stop Growing?
Bernese Mountain Dogs typically reach their full adult height of 23–27 inches by 15 to 24 months and their full adult weight of 70–115 lbs shortly after. 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..
Factors that influence growth include genetics, nutrition, and spay/neuter timing. For this working breed, a large-breed puppy food with controlled calcium is recommended to support proper joint development.
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?
To determine if your Bernese Mountain Dog is at a healthy weight (70–115 lbs target):
- Rib test: You should be able to feel the ribs without pressing hard, with a thin layer of fat covering them
- Waist check: Viewed from above, there should be a visible waist behind the ribs
- Tuck-up: From the side, the abdomen should tuck up behind the rib cage
Their long coat can mask weight gain, so hands-on assessment is essential. If your Bernese Mountain Dog is overweight, work with your veterinarian to develop a safe weight loss plan. Even a 10% reduction can reduce the risk of Histiocytic Sarcoma and other conditions.
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
Daily food for an adult Bernese Mountain Dog: 1.1–2.3 cups of high-quality dry food in two meals, budgeting $87–130/month. Puppies growing toward 70–115 lbs need three to four daily feedings until around six months old. Tragically short-lived for such a beloved breed, with histiocytic sarcoma being the primary concern; cancer research foundations actively work to improve breed longevity., treats count toward daily calorie intake.
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.
