If you share your home with a Bernese Mountain Dog puppy, you probably already know how quickly they change. One month they fit on your lap, and a few months later they are taking up most of the sofa. That fast growth is part of why so many owners start thinking about joint care very early.
A question many owners ask is when to start a joint supplement. The honest answer is that it depends, and your vet is the right person to guide you. A supplement can be one small part of a bigger picture that includes careful feeding, sensible exercise and a comfortable home.
This guide covers what makes a Bernese puppy's joints different, how to support steady growth, where a supplement fits, and which signs mean it is time to call your vet.
How the joint actives compare for a growing Bernese puppy
A Bernese puppy gains size quickly and keeps growing for a long time, so it pays to read the ingredients of any joint chew closely. The table below compares six UK options on the six key joint actives we look for.
MedPaw Hip & Joint Chews Max is our own product, and it sits in the first column so you can judge it against the rest.

MedPaw is the only one of the six that lists all six key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata. That scores 6 of 6. NutraPaw lists 4, YuMOVE and Nutraquin+ list 3, and Seraquin and Synoquin EFA list 2 each.
For a giant breed with a long growing period, that full range in one daily soft chew means you do not need to piece together a routine from several products. It also brings omega-3 from green-lipped mussel and flax seed, plus vitamins C and E and zinc, to support joints, mobility and comfort alongside veterinary care.
The feeding guide runs by weight, from 2 chews for 5-17kg to 2-3 for 18kg and over, so it follows your puppy as they grow. A 60-day money-back guarantee and Subscribe & Save are available too.
MedPaw contains green-lipped mussel, which is a shellfish, along with rapeseed oil and flax seed. If your dog has a shellfish allergy, needs a low-fat diet, is pregnant or nursing, or is still a growing puppy, check with your vet before starting any joint supplement.

Why a Bernese puppy's joints need extra thought
Bernese Mountain Dogs are a giant breed, and much of their growth is packed into roughly the first two years. That is a lot for developing joints, tendons and cartilage to cope with.
The main period of bone growth is thought to last until around 18 to 24 months, with the growth plates closing last. Treat those ages as a rough guide. Individual dogs vary, and your vet can tell you when your own dog is skeletally mature.
Large breeds like the Bernese can show age-related stiffness a little earlier than smaller dogs. That is no reason to worry on day one. It is a good reason to talk to your vet early about long-term joint care and to build good habits while your dog is young.
Joint conditions the breed is known for
Several joint conditions are discussed in connection with the breed. Hip dysplasia and elbow dysplasia are the best known, and both have a genetic component. Diet, body weight and exercise also influence how a dog develops, which is why the choice of breeder and the way you raise your puppy both matter.
Joint concerns often discussed in Bernese Mountain Dogs
| Condition | What it means in plain English | Good to know |
|---|---|---|
| Hip dysplasia | The hip joint does not form as snugly as it should | Has a genetic component; weight and growth also play a part |
| Elbow dysplasia | The elbow joint develops unevenly | Has a genetic component; may show as front leg lameness |
| Osteochondritis dissecans (OCD) | Cartilage does not develop normally during growth | Can affect the shoulder, elbow or knee |
| Cruciate ligament injury | A tear or strain of a key knee ligament | Mentioned more in adult dogs |
For guidance only, not a diagnosis.
Only a vet can say whether any of these is affecting your dog. If you spot something that seems odd, a check-up is always better than waiting to see.
Start with the breeder and your vet
Questions for the breeder
If you are still choosing a puppy, ask to see the BVA/KC hip and elbow scores for both parents. Good scores do not guarantee a dog will never have a joint problem, but they give useful background. A responsible breeder will be happy to talk them through with you.
Questions for your vet
Ask your vet when and how your puppy's hips and elbows should be assessed. Screening options and timing are the vet's call, so it helps to raise the topic at the first or second puppy visit. Your vet can also check your puppy's body condition and tell you whether growth looks steady.
Growing steadily: food and body weight
Feeding is one of the most useful things you can get right. A complete large-breed puppy food has controlled calcium and phosphorus levels, so your puppy grows at a steadier pace. The idea is that your puppy still reaches their full adult size, just a little more gradually. These foods are designed for puppies expected to be large as adults, which a Bernese certainly is.
- Do not add calcium or bone meal unless your vet specifically tells you to. Extra calcium can disrupt a giant breed puppy's growth.
- Follow the feeding guide on the food, and weigh your puppy regularly.
- Ask your vet to check the body condition score. The aim is a lean puppy, not a thin one.
- Count treats and training rewards as part of the daily allowance.
Staying lean matters for adults too. Extra weight puts more strain on the joints and can make a dog feel stiffer and less comfortable. If your dog needs to lose weight, speak to your vet before changing food, because dogs on a diet still need a complete, balanced meal.
Exercise during the growth phase
Bernese puppies are cheerful, sociable and often keen to keep going long after their bodies would prefer a rest. You get to set the pace for them.
What tends to help
- Several short walks rather than one long one.
- Free play at your puppy's own pace.
- Soft surfaces such as grass and sand in preference to hard pavement.
- Lifting your puppy, or using a ramp, to get in and out of the car.
- Swimming, introduced safely and gradually, as a low-impact way to build muscle.
What is worth limiting
- Forced, repetitive jumping and sprinting.
- Rough play with bigger or more boisterous dogs.
- Long, steep hill walks while your dog is still growing.
- Unrestricted stair use, particularly for a heavy puppy.
- Serious agility or intense training before your vet confirms your dog is skeletally mature.
Setting up a joint-friendly home
Small changes at home can make life easier for a large puppy. A thick, supportive bed helps your dog settle comfortably. Non-slip rugs or mats on hard floors help a heavy puppy get up without sliding, which is especially useful on laminate or tile.
Berners can also develop calluses on their elbows from lying on hard floors. Soft bedding and carpet are kinder than bare tile. In warm weather, a cooling mat can help guide your dog towards the right spot to rest.
Where a joint supplement fits
A joint supplement is a complementary feed. It sits alongside your vet's advice, good nutrition, weight control and sensible exercise. It is not a replacement for any of them.
What a supplement can and cannot do
Opinions differ on how early to start a supplement with a growing puppy, and there is no single established rule. Before giving any joint supplement to a growing puppy, ask your vet, and check the product label for minimum age and weight guidance.
It helps to be realistic. A supplement supports joint comfort and mobility as part of everyday care. It is not a medicine, and it does not replace veterinary care or promise a particular result. Joint tissue also changes slowly, so give any supplement time and ask your vet how long to try it before reviewing.
Ingredients owners commonly see
Joint products often include some of the following, used to support joint health:
- Glucosamine and chondroitin: a well-known pairing, and both are components found in cartilage.
- Green-lipped mussel: a natural source of omega-3 fatty acids and a common ingredient in dog joint products.
- MSM: a sulphur-containing compound often included in joint blends.
- Hyaluronic acid: a component of joint fluid, the lubricant inside joints.
- Omega-3 fatty acids: from sources such as fish oil, krill, green-lipped mussel or flax.
- Collagen: described as a building block of cartilage, tendons and ligaments.
- Supporting nutrients: manganese, vitamins C and E, and sometimes zinc.
About MedPaw Hip & Joint Chews Max
MedPaw Hip & Joint Chews Max is a daily soft chew, a complementary feed for dogs. Its key joint actives are glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata. It also contains omega-3 from green-lipped mussel and flax seed, plus vitamins C and E and zinc, and it is made with rapeseed oil and glycerine.
The feeding guide is based on weight: 1 chew a day up to 4kg, 2 chews for 5 to 17kg, and 2 to 3 chews for 18kg and over. The amount is doubled for the first three weeks, and we recommend two to three months of daily use. There is a 60-day money-back guarantee, and Subscribe & Save is available.
Because the guide goes by weight rather than age, a growing Bernese puppy is likely to land in the 18kg and over band for much of the growth period. Please speak to your vet first about whether it suits your puppy and how much to give. The green-lipped mussel is a shellfish-derived ingredient, so tell your vet about any supplement your dog takes, especially if your dog has allergies, is on medication or is due for surgery.
Comparing labels fairly
Whichever product you consider, compare the labels rather than the marketing. Look at which actives are listed, whether it is a chew, tablet or capsule, what the feeding guide says and what guarantee is offered. Based on the manufacturers' published information from September 2026, products differ quite a bit. For example, NutraPaw Joint Support is a tablet that lists glucosamine, MSM, green-lipped mussel, hyaluronic acid, turmeric and collagen, but not chondroitin or Boswellia. YuMOVE Joint Support PLUS Max is a tablet that lists glucosamine, green-lipped mussel, hyaluronic acid and fish oil, with chondroitin only via the mussel. Seraquin, Synoquin EFA and Nutraquin+ each use a different mix again, and their guarantees are not stated.
The best choice is the one that matches your dog's needs, suits how your dog likes to eat and has been approved by your vet. Always follow the label.
When to see a vet
With a giant breed, it is better to ask early than to wait and see. A supplement should never be used to cover up a problem that needs examining. Here is a rough guide to how quickly to act.
How quickly to act on mobility and health changes
Subtle or occasional changes
Stiffness after rest, difficulty rising, reluctance to climb stairs or jump into the car, or sitting and lying in unusual positions. Mention it at your next appointment, or sooner if it continues.
Signs that keep returning or look uncomfortable
Limping that lasts more than a day or two, comes and goes or follows exercise. A bunny-hopping run, a swaying back end, or reluctance to run or play. Yelping when touched, licking or chewing at a joint, swelling or heat in a joint, elbows held out to the side, or changes in appetite, mood or behaviour.
Sudden or severe signs
Sudden lameness or not putting weight on a leg needs prompt veterinary attention. A swollen, hard or tight belly, repeated unproductive retching, restlessness or heavy drooling could be bloat, which is an emergency. Contact a vet immediately.
Bloat (gastric dilatation-volvulus) can affect deep-chested breeds like the Bernese, so it is worth knowing the signs before you ever need them. If you are unsure whether something is an emergency, phone your vet or an out-of-hours service and describe what you are seeing.
A steady start for your Bernese
The best thing you can do for a Bernese puppy's joints is stay consistent with the basics. Choose a breeder who can show hip and elbow scores, feed a complete large-breed puppy food, keep your puppy lean, and let them build strength with short walks and soft surfaces. Make your home easy on big paws.
If you decide a joint supplement could be part of the routine, talk to your vet first, read the label carefully and give it time. Alongside good care, it can be a supportive part of a long-term routine for a dog who deserves plenty of comfortable years.
When should I start a joint supplement for my Bernese Mountain Dog puppy?
There is no single established age, and opinions differ on how early to start with a growing puppy. Speak to your vet first, because they know your puppy's growth, weight and breeding background. Always check the product label for any minimum age or weight guidance before giving anything.
When do a Bernese Mountain Dog's growth plates close?
Bone growth in a giant breed like the Bernese is thought to continue until around 18 to 24 months, with the growth plates closing last. That is only a rough guide, as individual dogs vary. Your vet can tell you when your own dog is skeletally mature, which is worth knowing before you build up exercise.
How much exercise should a Bernese puppy have?
Several short walks on soft surfaces such as grass tend to suit a growing Bernese better than one long outing. It is sensible to limit forced jumping, sprinting, rough play with bigger dogs and unrestricted stair use while they are still growing. Your vet can advise on the right amount for your puppy as they develop.
What hip and elbow scores should a Bernese puppy's parents have?
Ask the breeder to show the BVA/KC hip and elbow scores for both parents and talk you through them. Good scores do not guarantee a dog will never have a joint problem, but they give useful background. Your vet can also advise when and how your own puppy's hips and elbows should be assessed.
Can I give MedPaw Hip & Joint Chews Max to a Bernese puppy?
MedPaw Hip & Joint Chews Max is a complementary feed, and the label feeding guide goes by weight rather than age: 2 to 3 chews a day for dogs of 18kg and over, doubled for the first three weeks. A part-grown pup of around 21kg would fall in that band, but please ask your vet before starting a growing puppy. If the label does not state a minimum age, your vet is the right person to decide whether it suits your puppy.
What should I do if my Bernese puppy seems stiff or is limping?
Book a vet visit rather than relying on a supplement, as stiffness, limping or reluctance to jump can have many causes that need examining. Sudden lameness or not putting weight on a leg needs prompt veterinary attention. A supplement supports everyday joint comfort and should never be used to cover up a problem.
