A Great Dane puppy can seem to grow overnight. One week they fit on your lap, and a few months later they are looking over the kitchen counter. It is lovely to watch, but it can leave you wondering whether their joints can keep up.
If you are searching for joint supplements for a Great Dane puppy, the honest answer is that a supplement is an optional extra, not the foundation. The right diet, a lean body, sensible exercise and a good breeder do most of the work during the growing months. In this article we cover what matters most, where a supplement might fit later, and which signs mean a call to your vet.
Most joint supplements, including ours, are made for adult dogs. If your Dane is still growing, please speak to your vet before adding anything to the bowl.
Comparing joint formulas for a fast-growing Great Dane
A Great Dane carries giant-breed weight on a frame that keeps changing, so what a joint supplement actually contains matters more than the name on the pack. Below, MedPaw Hip & Joint Chews Max, our own product, is set against five well-known UK options.
The first row counts how many of six key joint actives each one lists, which gives you a quick way in before you look at format and guarantees.

MedPaw is the only product of the six to list all six key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata. NutraPaw lists four, YuMOVE and Nutraquin+ three each, and Seraquin and Synoquin EFA two. For a breed this large, having that broad a line-up in one daily product is a real advantage.
MedPaw is a soft chew, so it fits easily into a Dane's daily routine. It also includes omega-3 from green-lipped mussel and flax seed, plus vitamins C and E and zinc. Joints are supported over time, so 2 to 3 months of daily use is recommended, backed by a 60-day money-back guarantee and Subscribe & Save.
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 Great Danes are a special case
Few breeds grow as fast or as large as the Great Dane. A puppy that weighs well under a kilo at birth can reach an adult weight well over 50kg, depending on sex and build. That is a huge increase in body mass in under two years.
Most Danes reach their full height sometime in their second year, but their bodies keep developing until about two years old. During growth, bone length tends to run ahead of the muscle, tendon, ligament and cartilage that support it. That gap is why growth needs careful management.
Size matters later too. A fully grown male carries a lot of weight through the hips, elbows, shoulders and spine. Giant breeds also tend to age sooner than smaller dogs, so it makes sense to think about joint health earlier than you might for a terrier or a Labrador.
Growth-phase problems owners hear about
This section is for awareness only. Only a vet can diagnose any of these, and many dogs never develop them. Knowing the general pattern simply helps you spot when something does not seem right.
Joint and growth conditions commonly discussed in Great Danes
| Condition | Typical age | What owners may notice |
|---|---|---|
| Hypertrophic osteodystrophy (HOD) | Early in the rapid growth phase | Severe lameness, swollen joints, lethargy, poor appetite |
| Osteochondritis dissecans (OCD) | Often during the later puppy months | Lameness, most often linked to the shoulder, sometimes both sides |
| Panosteitis | Often during the growing months | Lameness that shifts from one leg to another |
| Elbow problems | Often during growth | Front leg lameness |
| Hip dysplasia | Can show during growth or later | Difficulty rising, a bunny-hopping gait, stiffness |
| Wobbler syndrome | Varies | Wobbly, uncoordinated gait, especially in the back legs |
For guidance only, not a diagnosis.
Genetics, fast growth and heavy body weight are all discussed as contributing factors for some of these. Some growth-related conditions change once the growth plates close, but they can be painful in the meantime. Early assessment gives your vet the best chance to guide you on pain relief, rest and monitoring.
Later in life, large and giant breeds can be prone to osteoarthritis, sometimes from middle age. That is one reason owners start thinking about joint support well before the senior years.
What matters more than a supplement during growth
If you take one thing from this article, let it be this: for a growing Dane, the basics come first. They are less exciting than a tub of chews, but they matter far more.
Feed a giant breed puppy diet
Large and giant breed puppy foods are made for slower, steadier growth. Measure portions every time rather than guessing by eye, and ask your vet to adjust amounts if your puppy is gaining too quickly. Excess weight and rapid growth are widely seen as undesirable for joints.
Take care with extras on top of a complete puppy food. Giant breed puppies have particular nutritional needs, including a careful mineral balance, and over-supplementing minerals such as calcium is a known concern. Check the labels of everything your puppy eats, and ask your vet before adding anything.
Keep your puppy lean
You should be able to feel your puppy's ribs easily without seeing them prominently. Your vet or practice nurse can give a body condition score and show you what to look for. Lean puppies put less load through developing joints.
Keep exercise gentle and controlled
A commonly used rule of thumb is about five minutes of exercise per month of age, up to twice a day. A four-month-old would have two sessions of around 20 minutes. It is a guide rather than a rule, so ask your vet what suits your puppy.
- Choose short, gentle lead walks on soft ground where you can.
- Avoid repeated jumping on and off furniture or out of the car.
- Skip long runs on hard surfaces and rough play with adult dogs.
- Limit stairs in the first year, and use baby gates if needed.
- Introduce swimming gradually once your puppy is confident, as it is low impact.
Set up your home
Smooth floors are a slipping hazard for long, growing legs. Non-slip rugs or mats help, as does supportive or orthopaedic bedding in a warm, dry spot. Ramps for the car and sofa save your puppy from repeated jumping.
A word on bloat and raised bowls
Great Danes are among the breeds most at risk of gastric dilatation-volvulus, known as bloat. Ask your vet about feeding routines. Advice on raised bowls is mixed. Some sources suggest they ease neck and shoulder strain, while others link them with a higher bloat risk in large and giant breeds. Please ask your vet before using one.
Choosing a puppy with joints in mind
Your best chance to support lifelong joint health starts before you bring a puppy home. A responsible breeder will be open about health testing.
- Ask to see the hip and elbow scores for both parents, and check them against the breed median with your vet's help.
- Ask about any history of Wobblers, growth conditions and the lifespan of the parents.
- Be cautious if a breeder will not share health certificates or only says the puppies are "vet checked".
None of this guarantees a problem-free dog, but it improves the odds and tells you a lot about how the breeder works.
Where a supplement fits for a puppy
Sources broadly agree on a few points. Diet, weight and exercise matter most during growth. You should speak to your vet before giving any supplement to a growing giant breed puppy. Many owners start a joint supplement once their Dane is fully grown, at around two years old, rather than waiting for the senior years.
Be wary of any product that claims it will prevent or protect against growth problems. No supplement can promise that. A joint supplement is a complementary feed, which means it supports joints and mobility alongside veterinary care. It does not diagnose, treat or replace it.
Ingredients you will see mentioned
If you read supplement labels, these are the names you are most likely to meet.
- Glucosamine and chondroitin: found naturally in healthy cartilage, and among the best-known joint supplement ingredients.
- Green-lipped mussel: a marine ingredient that supplies omega-3 fatty acids and glycosaminoglycans.
- Hyaluronic acid: a natural component of joint fluid.
- MSM: a source of sulphur.
- Boswellia serrata: a plant resin traditionally used to support joint comfort.
- Fish oil omega-3 (EPA and DHA): often discussed for general joint and overall health. Ask your vet about an appropriate amount for a growing puppy.
- Vitamins C and E, and zinc: supporting nutrients that appear in some formulas.
Collagen is another ingredient you may see promoted. Some of the strongest claims come from commercial sources, so treat them with a little caution and ask your vet if you are unsure.
When your Dane is fully grown
MedPaw Hip & Joint Chews Max is made for adult dogs, so we see it as an option for when your Great Dane has finished growing, or when your vet has advised it. It is a daily soft chew, sold as a complementary feed.
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.
Feeding guide
The pack guide is 1 chew a day up to 4kg, 2 chews for 5 to 17kg, and 2 to 3 chews for dogs of 18kg and over. The amount is doubled for the first three weeks. A fully grown Great Dane sits in the 18kg and over band. Please follow the pack guide, and check with your vet if you are unsure what is right for your dog.
We recommend 2 to 3 months of daily use before judging how a supplement suits your dog. It comes with a 60-day money-back guarantee, and Subscribe & Save is available if you prefer regular deliveries.
Comparing joint supplements fairly
There are several well-known UK options, and the right one depends on what you value. Based on each manufacturer's published information from September 2026, here are some factual differences.
- NutraPaw Joint Support is a tablet with glucosamine, MSM, green-lipped mussel, hyaluronic acid, turmeric and collagen. It does not list chondroitin or Boswellia, and it has a 90-day guarantee.
- YuMOVE Joint Support PLUS Max is a tablet with glucosamine, green-lipped mussel, hyaluronic acid and fish oil, with chondroitin only via the mussel. It has a 6-week guarantee.
- Seraquin Joint is a chewable tablet with glucosamine, chondroitin and turmeric.
- Synoquin EFA comes as a tablet or capsule with glucosamine, chondroitin and krill oil.
- Nutraquin+ is a capsule with glucosamine, chondroitin and Boswellia.
MedPaw is a soft chew and contains glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata, whereas the others vary in what they include. Some owners will prefer a product with turmeric or collagen, or a longer guarantee. Others will value a soft chew that is easy to give. Choose based on the ingredients that matter to you, the format your dog will actually accept and the guarantee that suits you.
If you decide to add a supplement
- Speak to your vet first if your Dane is still growing.
- Check the product is intended for your dog's life stage.
- Follow the feeding guide on the pack.
- Give it consistently for 2 to 3 months before judging how it suits your dog.
- Keep a simple mobility diary, noting getting up, stairs, walks and stiffness, to share with your vet.
When to see a vet
A supplement is never a substitute for a diagnosis. In a growing Dane, any limping, shifting lameness, wobbliness or loss of appetite needs a vet's assessment. This guide shows how quickly to act.
How quickly to act on mobility signs in a growing Great Dane
Mention it at the next check
Occasional clumsiness or a little sleepiness after a big play session that clears up quickly. Note it in your mobility diary and keep an eye on it.
Book an appointment soon
Limping or favouring a leg, lameness that moves between legs, difficulty standing up, a bunny-hopping gait, stiffness after rest that does not ease, swelling around the joints, tiring quickly, or being less playful or not wanting to be touched.
Contact a vet straight away
Refusing to bear weight, severe or sudden lameness, swollen painful joints with lethargy or poor appetite, a wobbly gait or reluctance to lower the head to eat, inability to rise, or signs of bloat such as a swollen abdomen, unproductive retching or restlessness. Bloat is an emergency.
Most growth-related lameness is better assessed early. Your vet may suggest pain relief, rest and monitoring, and may recommend changes to diet or exercise.
The bottom line for Great Dane owners
Great Danes grow at an extraordinary rate, so growth-phase care matters more than any single product. Put your effort into a giant breed puppy diet, a lean body, gentle exercise, a safe home and a breeder who shares health results.
Talk to your vet before giving any supplement to a growing puppy, and learn the warning signs so you never delay a visit. When your Dane is fully grown, you can compare options on ingredients, format and guarantee, and give any product a steady 2 to 3 months before deciding. With good care and your vet's guidance behind them, your big, gentle dog has the best foundation for an active life.
When should I start a joint supplement for my Great Dane puppy?
There is no single age that suits every puppy, and the basics matter far more during growth: a giant breed puppy diet, a lean body, gentle exercise and a breeder who shares health results. Many owners wait until their Dane is fully grown, at around two years old, before adding a joint supplement. Please speak to your vet before giving any supplement to a growing puppy.
Can I give MedPaw Hip & Joint Chews Max to a Great Dane puppy?
MedPaw Hip & Joint Chews Max is made for adult dogs, so we see it as an option for when your Great Dane has finished growing or when your vet has advised it. If your puppy is still growing, please ask your vet before starting, and do not add it on your own. It is a complementary feed, not a medicine.
How many chews would a Great Dane need once fully grown?
The pack guide is 1 chew a day up to 4kg, 2 chews for 5-17kg, and 2-3 chews for dogs of 18kg and over. A fully grown Great Dane sits in the 18kg and over band, and the amount is doubled for the first three weeks. A part-grown pup at around 31kg would also fall in that band, but please check with your vet before starting a growing puppy.
How much exercise should a Great Dane puppy have?
A commonly used rule of thumb is about five minutes of exercise per month of age, up to twice a day, so a four-month-old might have two sessions of around 20 minutes. Choose short, gentle lead walks on soft ground and avoid repeated jumping, long runs on hard surfaces and rough play with adult dogs. It is only a guide, so ask your vet what suits your puppy.
What hip and elbow health checks should a Great Dane puppy's parents have had?
Ask the breeder to show you the hip and elbow scores for both parents, and check them against the breed median with your vet's help. It is also worth asking about any history of Wobblers, growth conditions and the lifespan of the parents. Be cautious if a breeder will not share health certificates, as health testing improves the odds but never guarantees a problem-free dog.
What signs in a growing Great Dane mean I should call the vet?
Limping, lameness that moves between legs, difficulty standing up, a wobbly gait, swollen joints or a loss of appetite all need a vet's assessment. Sudden or severe lameness, refusing to bear weight or a swollen abdomen with unproductive retching needs a vet straight away, as bloat is an emergency. A supplement is never a substitute for a diagnosis.
