A Saint Bernard puppy is a lot of dog to love. Adults are among the heaviest of all breeds, and that frame starts growing fast from the first weeks. If you have one at home, or one on the way, it is natural to wonder how best to look after those joints from the start.
The honest answer is that the basics come first: good breeding, a lean puppy, sensible exercise and regular vet checks. A joint supplement is an optional extra that sits alongside all of that. It is not a substitute for any of it.
This guide covers why giant breeds need a little extra thought, what you can do day to day, how common joint ingredients are described, and how to talk to your vet about whether a supplement suits your puppy at all.
Comparing joint supplements for a growing Saint Bernard
Giant puppies grow fast, and the actives list on a joint supplement tells you far more than the front of the pack. Here is how six popular UK options compare on six key joint actives, with MedPaw, our own product, shown first.
Format matters with a big, enthusiastic pup too, so the table covers that as well as the ingredients.

MedPaw is the only one of the six listing all six key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata. NutraPaw lists four, YuMOVE and Nutraquin+ three, Seraquin and Synoquin EFA two. For a breed with such a heavy frame, having that range in one daily chew is the real advantage.
A part-grown Saint Bernard at around 34kg sits in the 18kg and over band, so that means 2 to 3 soft chews a day, doubled for the first three weeks. Daily use for 2 to 3 months is recommended for optimal results, supporting joints, mobility and comfort alongside lean growth and sensible exercise.
The 60-day money-back guarantee and Subscribe & Save also make it simple to stay consistent through those important early months.
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.
Meet MedPaw Hip & Joint Chews Max Soft, daily and made with all six key joint actives, it is a natural fit for the routine of a giant breed.
Why the Saint Bernard needs extra thought
The breed was developed for mountain rescue, which explains the heavy build. That size, combined with fast growth, puts a lot of load on joints that are still developing. Giant breeds are generally described as having a higher lifetime risk of orthopaedic problems than smaller dogs, and hip and elbow dysplasia are among the joint concerns most often flagged in Saint Bernards.
That is a reason to be proactive, not to panic. Plenty of Saint Bernards live comfortable lives. A few things stand out for owners.
Weight and growth rate
Every extra kilo is magnified in a giant breed. Managing your puppy's weight is one of the basics that no supplement can replace. A puppy that grows too quickly or carries extra condition puts more strain on its joints than one that grows steadily and stays lean.
Family history
Hip and elbow problems can run in families, so your puppy's parentage matters. This is why the breeder you choose is such an important early decision.
Exercise load
Heavy dogs put a lot of force through their joints, so how and when a puppy exercises matters as much as what it eats. We cover practical exercise tips below.
A shorter timeline than you might expect
Giant breeds generally have shorter lifespans than smaller dogs, and they are said to age more quickly. That is why looking after joints early is about building good habits for the whole of your dog's life, not just the puppy months.
Practical steps that matter most
These are the things that make the biggest difference, and none of them come in a tub or a packet. Steady habits do most of the work.
Ask about parentage
Reputable UK breeders can share hip scores and elbow grades for the parents under the BVA/Kennel Club schemes. Lower scores are generally better. Ask to see the paperwork before you commit.
Keep your puppy lean
You should be able to feel the ribs under a light covering of flesh. Ask your vet to check body condition at every visit. Giant-breed puppies are usually fed a food formulated for large-breed growth, so ask your vet to recommend one and advise on portions, rather than switching around.
Manage exercise sensibly
Favour short, frequent, gentle walks and free play on soft surfaces. Avoid repetitive jumping, long forced runs and lots of stairs while the joints are still developing. Many vets give a rough guide based on minutes of exercise per month of age, so ask what they recommend for your puppy.
Help with traction
A heavy, clumsy puppy on a slippery floor is a recipe for slips. Rugs or mats help, and a ramp for the car saves repeated jumping in and out.
Keep a simple diary
Note how your puppy gets up, climbs stairs and plays. Photos or short videos of movement are very useful to show your vet, because puppies often behave differently in a consulting room.
Puppies and joint supplements: what to ask first
You will sometimes see advice to start joint support "earlier than you think". Much of that advice is aimed at adult dogs, and it does not tell you what to do with a puppy that is still growing. There is no universal age to start.
The best first step is to raise it with your vet, ideally at a puppy check or vaccination appointment. They can tell you whether a supplement suits your puppy's stage of growth, and when.
- Check the label. Look for a minimum age and for dosing guidance on any product you are considering.
- Never guess an adult dose. Dosing is weight-based, so it is best to get the amount right for your puppy's current weight rather than estimating.
- Introduce one new thing at a time. That way, if your puppy has any digestive upset, you can tell what caused it.
- Agree a plan. Settle the product, the amount for your puppy's current weight, and when you will review how things are going.
Common joint-support ingredients, explained
Most dog joint supplements are built from a similar set of ingredients. Here is what each is generally associated with, in plain English. Joint ingredients are widely used to support comfort and mobility, and results vary from dog to dog.
Common joint-support ingredients and what they are associated with
| Ingredient | What it is | Why it is used |
|---|---|---|
| Glucosamine | A building block found in cartilage | Associated with cartilage structure |
| Chondroitin | A component of cartilage | Associated with cartilage's ability to hold water and cushion weight |
| MSM | A source of sulphur | Sulphur is part of connective tissue |
| Green-lipped mussel | A marine source of glucosamine, chondroitin and omega-3 | Omega-3 is linked with supporting a balanced inflammatory response |
| Omega-3 fatty acids | Essential fats from marine or plant sources | Commonly linked with joint comfort and skin health |
For guidance only, not a diagnosis.
How long before you notice anything?
It can take several weeks of daily use before you notice any change, which is why consistency matters. A supplement given on and off, or for a fortnight, gives you very little to judge. The format matters too. A puppy that happily eats a soft chew is more likely to get it every day than one that spits out a tablet.
MedPaw Hip & Joint Chews Max: the facts
MedPaw is our product, so here are its details, kept separate from anyone else's.
- Format: a daily soft chew, sold as a complementary feed for dogs.
- Key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata.
- Also contains: omega-3 from green-lipped mussel and flax seed, vitamins C and E, and zinc. It is made with rapeseed oil and glycerine.
- Feeding guide: 1 chew a day up to 4kg, 2 for 5 to 17kg, and 2 to 3 for 18kg and over. The amount is doubled for the first three weeks, and 2 to 3 months of daily use is recommended.

Our feeding guide is based on weight bands, and it does not give a puppy-specific age range. We are not saying MedPaw is designed for puppies. If you are considering it for a young Saint Bernard, check the label and talk to your vet first. The 18kg and over band would only apply once your puppy actually reaches that weight, and the amount should be rechecked as they grow.
How other UK options differ
It helps to know what else is out there. The details below come from each manufacturer's published information as of September 2026.
- NutraPaw Joint Support is a tablet containing glucosamine, MSM, green-lipped mussel, hyaluronic acid, turmeric and collagen, with omega-3 from the mussel and manganese. It does not list chondroitin or Boswellia. It has a 90-day guarantee.

- Seraquin Joint is a chewable tablet containing glucosamine, chondroitin and turmeric. It does not list MSM, green-lipped mussel, hyaluronic acid, Boswellia, omega-3 or collagen. A guarantee is not stated.
- Synoquin EFA comes as a tablet or capsule and contains glucosamine, chondroitin and krill oil, plus vitamin C and zinc. It does not list MSM, green-lipped mussel, hyaluronic acid, Boswellia, turmeric or collagen. A guarantee is not stated.
- Nutraquin+ is a capsule containing glucosamine, chondroitin and Boswellia, plus vitamin C and zinc. It does not list MSM, green-lipped mussel, hyaluronic acid, omega-3, turmeric or collagen. A guarantee is not stated.
A long ingredient list is not proof of quality. Look at what is in a product, in what amount, whether the format suits your dog, and whether the dosing fits your puppy's weight. Your vet can help you weigh those up.
Bloat: a breed emergency worth knowing
This is not a joint issue, but it matters for any Saint Bernard owner. Large, deep-chested dogs are among the most susceptible to bloat (gastric dilatation-volvulus), where the stomach swells and can twist. No supplement will stop it from happening.
Day-to-day habits that help include smaller, multiple meals and avoiding vigorous exercise around mealtimes. Treat suspected bloat as an emergency and phone a vet immediately. Signs include a swollen or tight belly, retching without producing anything, restlessness, drooling and obvious distress.
When to see a vet
You know your puppy best. If something looks off, trust that instinct and ask. Here is a rough guide to how quickly to act.
How quickly to seek veterinary advice
Mention it at the next check
Growing unusually fast, carrying a little extra weight, or slipping often on smooth floors. Ask about portions, diet and exercise.
Book an appointment promptly
Limping that comes and goes, bunny hopping when running, a swaying back end, reluctance to climb, jump or get up, sitting to one side, stiffness after rest, tiring quickly, swollen joints, or flinching when hips, elbows or legs are touched.
Get help straight away
Sudden severe lameness, inability to stand, a visibly swollen abdomen or any signs of bloat. Phone your vet or an emergency service immediately.
A supplement should never delay a diagnosis. Your vet may suggest X-rays or other checks, and can advise whether a joint supplement is appropriate alongside any prescribed treatment.
The bottom line for Saint Bernard owners
Good breeding, lean steady growth, sensible exercise and regular vet checks come first. They do more for a giant breed puppy's joints than anything you can add to a bowl.
If you and your vet decide a supplement has a place, treat it as an optional extra. Agree the product and the amount for your puppy's current weight, give it consistently, and allow several weeks before judging how it is going. If you are following MedPaw's guidance, plan around 2 to 3 months of daily use, and review the amount as your puppy grows.
When should I start a joint supplement for my Saint Bernard puppy?
There is no single age that suits every puppy, so the best first step is to ask your vet, ideally at a puppy check or vaccination visit. They can advise whether a supplement suits your puppy's stage of growth and when. Check the label of any product for a minimum age, and if none is printed, ask your vet before starting.
Is MedPaw Hip & Joint Chews Max suitable for a Saint Bernard puppy?
The MedPaw label gives feeding amounts by weight band and does not print a minimum age. Because of that, we would ask you to speak to your vet before giving it to a puppy. It is a complementary feed, not a medicine, and is intended to support mobility and comfort.
How many MedPaw chews would a 34kg Saint Bernard puppy need?
On the label, the 18kg and over band is 2 to 3 chews a day, doubled for the first three weeks, with 2 to 3 months of daily use recommended. A part-grown pup at 34kg would fall in that band, but a puppy's amount should be agreed with your vet and rechecked as they grow. Adult weight uses the same band, so the amount is guided by weight rather than age.
What hip and elbow checks should a Saint Bernard puppy's parents have had?
Reputable UK breeders can show hip scores and elbow grades for the parents under the BVA/Kennel Club schemes. Lower scores are generally better, so ask to see the paperwork before you commit. Screening does not guarantee a puppy's joints, but it is one of the most useful questions to ask a breeder.
How much exercise should a growing Saint Bernard puppy have?
Short, frequent, gentle walks and free play on soft surfaces are usually favoured, while repetitive jumping, long forced runs and lots of stairs are best avoided. Many vets give a rough guide based on minutes of exercise per month of age, so ask what they recommend for your puppy. Rugs or mats on slippery floors and a ramp for the car also help.
Which signs in my Saint Bernard puppy should I take to the vet?
Limping that comes and goes, bunny hopping when running, a swaying back end, reluctance to climb or get up, stiffness after rest, swollen joints or flinching when touched are all worth an appointment. A supplement should never delay a diagnosis. If your puppy has a swollen belly, retches without producing anything or cannot stand, phone your vet or an emergency service straight away.
