How Much Exercise a Bernese Puppy Needs (and What Hurts Growing Joints)

By the Riverside Berner Guide editorial team
Last updated November 7, 2026

Bernese puppy exercise should be regular, gentle and mostly self-paced, not forced. No veterinary school or breed club gives a set number of minutes. The Bernese Mountain Dog Club of America (BMDCA) advises supervised exercise matched to each puppy, and the AKC says to hold off on jogging until 14 to 18 months, when large-breed growth plates close.

Below is what the sources agree on, what the research actually found, and how strong that evidence is. Joint health is a medical topic, so ask your vet about your own puppy.

Bernese puppy exercise: what the sources agree on

The BMDCA’s first-year guide says puppies need regular, supervised exercise in a safe, dog-friendly outdoor space. That keeps muscles toned and the puppy in good condition.

The club lists walking, running, swimming and gentle play, all based on your puppy’s condition and ability. It says exercise should never be forced, giving jogging and long rough play as examples.

Vet sources say much the same. Cornell’s Riney Canine Health Center advises regular exercise that fits the dog’s age, and avoiding repetitive high-impact or forced activity during rapid growth. Its example is long-distance running on hard surfaces.

Self-paced play is the model

The AKC’s large-breed care guide says puppies are often advised to stick to self-regulated play until their growth plates close. That means the puppy sets the pace and can stop when it’s tired.

The same guide prefers normal puppy play, with lots of twisting and turning and no single motion held for long. It warns that regimented running or jogging on concrete or asphalt may harm developing joints, and suggests grass or sand instead.

Large breed puppy exercise and growth plates

A puppy’s long leg bones grow from areas called growth plates. The AKC explains that these are soft and somewhat flexible during puppyhood, then harden and close once the bone reaches its final size.

Big dogs take longer. The AKC’s large-breed guide says growth plates in large and giant breeds close around 16 to 18 months, compared with 6 to 9 months in toy breeds.

That timing drives the jogging advice. Quoting its chief veterinarian, the AKC says jogging or road work is never recommended in a dog younger than 14 to 18 months, especially in large and giant breeds, until the growth plates have fully closed. It adds that short walks on softer ground, such as grass, are generally safer.

Berners are slow to grow up in other ways, too. The BMDCA’s FAQ sheet says the breed can be slow to mature, and that many Berners’ bodies grow faster than their “brains.” Our guide to when Bernese Mountain Dogs calm down covers that stage.

What research says about exercise and hip dysplasia

The advice above comes from club and veterinary guidance pages. The most direct research we found comes from one Norwegian group that followed hundreds of puppies from birth.

The stairs and off-leash study

The 2012 study in the American Journal of Veterinary Research tracked 501 puppies from 103 litters. They were Newfoundlands, Labrador Retrievers, Leonbergers and Irish Wolfhounds, followed from birth until hip screening at 12 or 18 months. Questionnaires recorded how the puppies were housed and exercised.

Puppies that walked on stairs from birth to 3 months had a higher risk of hip dysplasia on X-rays. Off-leash exercise from birth to 3 months was linked to a lower risk, as were being born in spring or summer and being born on a farm.

The authors concluded that puppies 3 months old or younger shouldn’t use stairs. They suggested outdoor exercise on soft ground in moderately rough terrain instead.

Later follow-up

The same group followed 494 of these dogs for up to 9 years, looking at hip problems a vet diagnosed. Dogs that had access to off-leash exercise at 12 months had a lower hazard of those hip problems later.

How strong is this evidence?

It’s useful, but it has limits. These were observational studies: researchers watched what owners did and didn’t assign exercise. So they show links, not proof that stairs cause dysplasia.

The data came from questionnaires, and none of the four breeds was the Bernese. The stair and off-leash findings also cover only the first 3 months of life.

We found no study of exercise and joint health in Bernese puppies specifically. Until one exists, the Norwegian results are the closest guide, and your vet can help you apply them.

Litters matter, too. In an earlier paper on the same dogs, hip dysplasia clustered strongly within litters, and the authors called for more study of the genetic part of that pattern.

The Orthopedic Foundation for Animals (OFA) says that things like calorie intake and exercise level can affect how severe the disease becomes. Our guide to hip and elbow dysplasia in Berners covers screening and genetics.

Stairs, jumping and slippery footing

Elbows matter as much as hips. Cornell’s elbow dysplasia page says repeated jumping down from beds, couches or car seats can injure front legs. Frequent trips up and down long staircases add stress too.

Cornell notes that breeders often keep puppies to just a few stairs until about 6 months. Young dogs are more vulnerable than adults, it says.

At home, that can mean planning how your puppy gets in and out of the car and off the furniture. Ask your vet when stairs and jumping are fine for your puppy’s age.

Playing with other dogs

Play with other dogs builds social skills, and the AKC’s large-breed guide calls play with well-mannered dogs one of the best activities. The BMDCA adds a warning: unsupervised play with older or larger dogs can easily injure a puppy and may cause lasting damage.

One older study points the same way. A 1992 study compared 31 dogs with osteochondritis dissecans (OCD), a joint cartilage disease, to 60 similar dogs without it. Playing with other dogs was linked to higher risk, along with high dietary calcium.

That was a small study, and it found a link, not a cause. Put together, the sources point to calm playmates and close supervision. Our Bernese puppy training guide covers early socialization.

The five-minute rule: what the evidence says

You’ll often see a rule of five minutes of exercise per month of age, twice a day. We looked for it in the veterinary schools, vet associations, breed clubs and peer-reviewed studies we use as sources.

None of them states it, and we found no study that tests it. The research above measured kinds of activity, like stairs and off-leash play, not minutes on a clock.

So we don’t give the rule as advice. If you want a daily target for your puppy, ask your vet, who can see how your puppy moves and grows.

How much exercise does a Bernese Mountain Dog puppy need over time?

There’s no sourced minute count for each month. What the sources give you is a direction: gentle, varied, self-paced activity now, building toward an adult’s needs once growth is done.

For grown Berners, the BMDCA’s FAQ says a daily minimum of 30 minutes of moderately vigorous exercise, plus several trips outside, is enough for some dogs. Others need considerably more.

Things that shape a good day

• Meals. The BMDCA’s first-year guide says to wait at least an hour after eating before exercise, because of bloat risk. See our Bernese puppy feeding chart for meal timing.
• Weight. OFA calls weight control a main goal for dogs with hip dysplasia, because extra weight stresses the hips. A lean puppy carries less load.
• Heat. The BMDCA’s FAQ says the breed does not do well in hot, humid weather. See keeping a Berner cool.
• Swimming. OFA calls swimming a good choice for dogs with hip dysplasia, since it puts less strain on the joint. Ask your vet whether it suits your puppy.

Sports, running and carting

The AKC’s large-breed guide says training for jumping sports like agility should be modified until growth plates close. It advises asking your vet before starting sports with running and jumping.

Pulling work is a later goal too. Read our guide to carting and drafting with a Bernese, and get your vet’s okay first.

Signs to stop and call your vet

Puppies get tired and sore like anyone, but some signs need a vet. Cornell lists lameness after exercise that doesn’t fully go away with rest as a sign of elbow dysplasia.

The BMDCA’s Diseases & Conditions page describes joint problems that can show up during growth:

• Panosteitis affects growing dogs, usually from 5 to 8 months and up to 2 years, with lameness that can move from leg to leg.
• Elbow dysplasia can cause lameness in puppies as young as 5 months.
• Hip dysplasia can appear from 6 months of age.

Don’t try to diagnose these at home. If your puppy limps, stops wanting to play or seems sore, rest it and ask your vet.

Screening ages to ask about

Cornell says puppies of at-risk breeds can be checked for hip looseness with PennHIP before 20 weeks. OFA offers preliminary hip X-ray readings from 4 months, but final ratings need a dog at least 24 months old. Ask your vet which screening fits your plans.

Questions to ask your vet and breeder

• What kind of exercise does my puppy get now, and on what surfaces?
• How should we handle stairs, jumping and car rides at this age?
• Which signs of soreness should make me call you?
• When can we start longer walks, running or sports?
• Should we screen hips early, and when?
