Bernese Mountain Dog: feeding, nutrition and health
The Bernese Mountain Dog is a giant breed with a short lifespan of 7 to 10 years and a high risk of cancer. Its diet has to manage two jobs at once: slow, controlled growth as a puppy, and preventing bloat and obesity as an adult.

How much food does a Bernese Mountain Dog need?
The calculator starts at the breed average of 43 kg (95 lb). Put in your own dog's weight and the energy figure from the bag.
On the bag this is the metabolisable energy (ME). If it is given per kg, divide by 10. If it is in kJ, divide by 4.184.

Feeding a Bernese Mountain Dog: what matters
For a Bernese Mountain Dog, slow, even puppy growth is the priority. A giant-breed food with an energy density around 340 to 360 kcal/100 g and a controlled calcium-to-phosphorus ratio protects growing joints from being overloaded. The goal is a lean, slowly growing puppy, not a fast-growing giant.
An adult dog weighing 40 kg (88 lb) needs roughly 1,600 to 1,900 kcal a day depending on activity, so less energy per kilogram than smaller breeds. Split feeding into 2 to 3 smaller meals a day, never one large one, because of the risk of bloat, which this deep-chested breed is prone to.
Given the high cancer risk and short lifespan, it makes sense to invest in a food with quality animal protein, omega-3 fatty acids, and a good level of antioxidants, rather than cheap substitutes built on soy or excess grain. Regular weight checks throughout life matter just as much, since every healthy year counts for this breed.

What to watch for
- Body condition: excess weight is hard to spot under a dense coat on a giant breed, so check the ribs and waist by hand regularly.
- Puppy growth rate: too rapid a weight gain raises the risk of dysplasia, so weigh the puppy and track its growth curve.
- Feeding around exercise: no vigorous activity for an hour before or after meals because of the risk of bloat.
- Heat and hydration: in summer, ensure plenty of fresh water and feed during the cooler parts of the day.
Practical feeding tips
- Split the daily ration into 2 to 3 meals at set times, rather than leaving food out at all times.
- Use a giant-breed food until at least 18 to 20 months of age.
- Check the puppy's weight every 2 weeks and compare it against the breed's growth curve.
- Reduce the daily ration by 15 to 20 percent after neutering; the risk of excess weight is high in this breed.
- Avoid exercise, play, and long walks right after a meal.
Feeding schedule by age
| Stage | Meals a day | Note |
|---|---|---|
| Puppy 8 to 12 weeks | 4x | A giant-breed puppy food with controlled calcium, fed in small, frequent portions. |
| Puppy 3 to 8 months | 3-4x | The fastest phase of skeletal growth; keep the puppy lean, not chubby. |
| Junior 8 to 20 months | 3x | Stay on a giant-breed food until skeletal growth is complete. |
| Adult 20 months to 6 years | 2-3x | An adult giant-breed food, split into portions because of the risk of bloat. |
| Senior from 6 years | 2-3x | Lower energy content, joint and heart support, and consistent weight monitoring. |
Health risks that diet affects
Histiocytic sarcoma
An aggressive cancer that Bernese Mountain Dogs develop far more often than other breeds, and the leading cause of the breed's short lifespan. There's no direct dietary prevention, but keeping the dog lean and providing quality antioxidant nutrition reduce overall strain on the body.
Hip and elbow dysplasia
An inherited joint defect that's substantially worsened in a giant breed by rapid growth, excess weight, and too much calcium during puppyhood. A giant-breed food with controlled calcium (1.0 to 1.5 percent on a dry matter basis) and energy content is the basic prevention.
Bloat (gastric dilatation-volvulus)
The Bernese Mountain Dog's deep chest is a risk factor for bloat. Feeding 2 to 3 times a day instead of one large meal, resting for at least an hour after eating, and avoiding boisterous activity on a full stomach all lower the risk.
Obesity
A calm temperament and low energy expenditure mean the Bernese Mountain Dog gains weight easily, especially after neutering. Excess weight further strains the joints and heart and shortens an already short lifespan for this breed.
Degenerative myelopathy
A progressive, genetically based spinal cord disease affecting older dogs of this breed. Diet can't directly influence it, but keeping the dog at an ideal weight reduces strain on the spine and eases movement in the disease's advanced stages.
Temperament and exercise
The Bernese Mountain Dog is a calm, somewhat easygoing companion with a lower exercise need than other working breeds. It copes poorly with heat and exertion in warm weather, which also affects feeding timing and hydration in summer.
Despite its size, it isn't a chowhound like the Labrador, but its calm temperament and lower activity level create a real risk of excess weight if the owner feeds according to the amount on the bag without regard to actual energy expenditure. Body condition needs regular checking, not guesswork.
A puppy reaches full height fairly quickly, but its skeleton doesn't finish maturing until around 18 to 20 months. Excess energy and calcium during this period directly increase the risk of hip and elbow dysplasia, which is why a giant-breed food formulated for slow growth is essential.
Coat: Long, dense, slightly wavy tricolor coat (black, rust, and white) with a thick undercoat; sheds noticeably year-round, more heavily twice a year.
Common questions about feeding a Bernese Mountain Dog
How much should a Bernese Mountain Dog weigh?
Under the FCI standard, males weigh 38 to 50 kg (84 to 110 lb) and females 36 to 48 kg (79 to 106 lb), standing 64 to 70 cm and 58 to 66 cm at the shoulder respectively. For a giant breed, condition matters more than the exact number; the ribs should be easy to feel and there should be a visible waist.
How much food does a Bernese Mountain Dog need per day?
An adult dog weighing 40 kg (88 lb) with average activity needs roughly 1,600 to 1,900 kcal a day, which works out to about 450 to 540 g of a typical kibble (350 kcal/100 g) split into 2 to 3 meals. A less active or neutered dog needs 15 to 20 percent less.
What food is suitable for a Bernese Mountain Dog?
A giant-breed food with 23 to 28 percent protein, 10 to 15 percent fat, a controlled calcium-to-phosphorus ratio, and no excess grain. Puppies need a food formulated for slow, controlled growth, not a standard small-breed puppy kibble.
How long do Bernese Mountain Dogs live?
Average lifespan is 7 to 10 years, among the shortest of any dog breed, mainly because of the high rate of cancer. Keeping the dog lean and feeding a quality diet throughout life are among the few factors an owner can genuinely influence.
Why is bloat a risk for Bernese Mountain Dogs?
The deep, narrow chest typical of this breed is one of the main risk factors for bloat and stomach twisting (GDV). Feeding 2 to 3 times a day instead of one meal, resting after eating, and a slow-feed bowl for dogs that gulp their food all lower the risk.
When should a Bernese Mountain Dog switch to adult food?
Usually between 18 and 20 months of age, when skeletal growth is complete. There's no benefit to rushing this for a giant breed; switching too early to a more energy-dense adult food can disrupt the slow, even growth of the skeleton and joints.
Breeds of a similar size

Cane Corso
Giant · 40–50 kg · 9–12 years
The Cane Corso is a massive Italian mastiff-type breed with rapid growth, making control of a puppy's growth rate and prevention of bloat essential. Its muscular build tempts owners into overfeeding, which needlessly strains joints already under pressure.

Great Dane
Giant · 45–90 kg · 7–9 years
The Great Dane carries the highest risk of bloat and stomach torsion of any dog breed. Feeding small meals several times a day and enforcing quiet time afterward isn't an optional tip here, it's a necessity. Just as critical is an extremely slow, controlled growth rate for a giant breed puppy.

Irish Wolfhound
Giant · 40–70 kg · 6–8 years
The Irish Wolfhound is the tallest breed in the world, and also one of the shortest-lived, at just 6 to 8 years. Its diet has to manage an extremely slow-growing giant puppy, protect the heart from cardiomyopathy, and prevent bloat in the deepest-chested breed of all dogs.

Leonberger
Giant · 45–77 kg · 7–9 years
The Leonberger is a massive giant breed with a short lifespan of just 7 to 9 years and an inherited nerve disease that can complicate eating. Nutrition has to support slow, controlled growth in a giant puppy and help prevent bloat, cancer, and obesity in adulthood.
