If you are weighing up joint supplements for your dog, it is easy to end up with a browser full of tabs and a lot of similar-sounding names. Seraquin and Cosequin often come up together, and it is fair to wonder how they differ.
This article looks at what Seraquin Joint contains, what the information we reviewed says about Cosequin, and how to compare labels sensibly. Cosequin's details come from a US-based overview, so the range sold in the UK may differ. Please check the current label on any product you are considering.
One thing applies to all of them. A joint supplement is a complementary feed that sits alongside veterinary care. It can support joint comfort and mobility as part of everyday care, but it does not replace a diagnosis from your vet.
Seraquin next to MedPaw: how the six key actives compare
Choosing between Seraquin and Cosequin comes down to what is actually in each daily dose. Before you decide, it helps to see Seraquin Joint on a wider grid, alongside MedPaw Hip & Joint Chews Max, our own product, and four other UK joint supplements.
The table opens with a score for six key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata. Cosequin is not in this table, so hold its current UK label up against the same six.

✓ = included, ✗ = not listed. Key joint actives: glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia. Taken from each manufacturer's published information, September 2026.
Seraquin Joint scores 2 of 6. It lists glucosamine and chondroitin, plus turmeric, but the table shows no MSM, green-lipped mussel, hyaluronic acid or Boswellia serrata. It is a chewable tablet with a short, simple formula.
MedPaw is the only product in the table with all six key actives, scoring 6 of 6. For an owner comparing two familiar names, that gives a third option with a much broader formula, supporting joint comfort and mobility alongside your vet's advice.
MedPaw is also a daily soft chew with omega-3 from green-lipped mussel and flax seed, plus vitamins C and E and zinc. There is a 60-day money-back guarantee, and Subscribe & Save if you decide to continue.

What is in Seraquin Joint
Seraquin Joint is a chewable tablet. From the manufacturer's published information, the ingredients it lists are glucosamine, chondroitin and turmeric. It is a short, focused formula built around the familiar glucosamine and chondroitin pairing, with turmeric added.
It helps to know what is not listed too, so you can compare fairly. Seraquin does not list MSM, green-lipped mussel, hyaluronic acid, Boswellia serrata, omega-3 or collagen. A guarantee is not stated in the information we reviewed.
None of this makes it a poor choice. Some owners like a simple ingredient list, and some dogs do well on a straightforward formula. It simply means Seraquin is narrower than some other products on the market.
What the information says about Cosequin
The overview we looked at describes Cosequin as a range rather than a single product. Every Cosequin product in it contains glucosamine hydrochloride and chondroitin sulfate. That is the same core pairing found in Seraquin.
Beyond that, the range appears wider. The source says MSM and Boswellia serrata extract appear in some Cosequin products, and that hyaluronic acid is available within the range. It does not say exactly which product has which, so the individual label matters.
It also mentions the following:
- Omega-3: the soft chews are described as the only products from that manufacturer offering omega-3 fatty acids, from fish oil.
- Formats: soft chews and sprinkle capsules are mentioned, the capsules in the context of cats.
- Strengths: standard, maximum strength and senior versions are referred to.
The same manufacturer also makes Dasuquin, which adds avocado-soybean unsaponifiables (ASUs). Cosequin does not contain these, and neither does Seraquin. Treat the source's claims as the manufacturer's own positioning, not independent proof.
Seraquin and Cosequin compared in plain words
The two share a base. Both contain glucosamine and chondroitin. Seraquin then adds turmeric, which the Cosequin information does not mention.
Cosequin's range is broader. Depending on the product, it may include MSM, Boswellia, hyaluronic acid or omega-3, none of which Seraquin lists. On format, Seraquin is a chewable tablet, whilst Cosequin is described as soft chews and capsules, among others.
On guarantees, Seraquin's is not stated, and the Cosequin source does not cover the topic. If a money-back guarantee matters to you, check the retailer or manufacturer page before you buy.
Glucosamine and chondroitin in plain English
Glucosamine and chondroitin are naturally occurring compounds found in joint structures. They are among the most widely used ingredients in dog joint supplements. Glucosamine is generally linked with cartilage, and chondroitin with joint cushioning and lubrication.
Supplements containing them are given to support joint comfort and mobility as part of everyday care. They are not a quick fix, and every dog responds differently. Your vet is the right person to work out why your dog is stiff in the first place.
What the other ingredients are
Labels can read like a chemistry exam, so here is a short guide to the extras mentioned in this article. It describes each ingredient in general terms and does not show how well any one product works.
Joint supplement ingredients in plain English
| Ingredient | What it is | Why it is often included |
|---|---|---|
| Turmeric | A plant ingredient | Often added to joint formulas as a plant-based extra |
| MSM | A naturally occurring sulphur compound | To support general joint wellbeing |
| Boswellia serrata | A plant resin extract | Often included in formulas intended to support joint comfort |
| Hyaluronic acid | A component of joint fluid | To support joint lubrication |
| Omega-3 | Fatty acids from fish oil or green-lipped mussel | For general wellbeing as well as joint support |
For guidance only, not a diagnosis.
We have no study results to quote for any of these, so we will not pretend otherwise. What matters is that you know what is on the label and why it might be there.
How to choose between joint supplements
Names can be misleading, so compare the labels themselves. Here is a simple checklist you can use for Seraquin, Cosequin or anything else.
- Ingredients: check which joint actives are listed, and which are missing.
- Format: tablet, chew or capsule. A supplement can only be part of your dog's routine if they actually eat it, so think about what yours will happily accept.
- Daily amount: check the feeding guide for your dog's weight, and whether there is a loading period at the start.
- Guarantee: see whether one is stated and how long it lasts.
- Vet advice: mention it at your next visit, especially if your dog takes prescribed medication.
Consistency matters more than switching around. Joint supplements are generally given daily over weeks rather than used as a one-off. Note your start date so you can review progress properly with your vet.
Think about your dog's temperament
Some dogs will happily take a tablet tucked into a bit of food. Others spit out anything with a firm texture. A dog that refuses tablets may take a soft chew more easily, and the reverse can be true as well. It is a very ordinary reason to choose one format over another.
Where MedPaw fits as an alternative
If you would like a broader ingredient list than Seraquin offers, MedPaw Hip & Joint Chews Max is one alternative. It is a daily soft chew, sold as 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, vitamins C and E, and zinc, and it is made with rapeseed oil and glycerine.
Compared with Seraquin, MedPaw lists MSM, green-lipped mussel, hyaluronic acid, Boswellia and omega-3, which Seraquin does not list. Seraquin lists turmeric, which MedPaw does not. MedPaw is a soft chew, whereas Seraquin is a chewable tablet.
Feeding and guarantee
The MedPaw feeding guide is 1 chew a day for dogs up to 4kg, 2 for 5-17kg, and 2-3 for dogs of 18kg and over. The amount is doubled for the first three weeks. We recommend daily use for 2-3 months.
There is a 60-day money-back guarantee, and Subscribe & Save is available if you would like regular deliveries.
Everyday support that does not come in a pack
Whichever product you pick, a supplement is only one part of looking after a stiff dog. Small changes at home often make a real difference to comfort.
- Weight: extra weight puts more load on joints. Ask your vet or vet nurse for a target weight and a feeding plan.
- Exercise: short, steady lead walks usually suit stiff dogs better than occasional long or high-impact sessions.
- Floors: non-slip rugs on hard floors give paws something to grip.
- Bedding: a supportive orthopaedic bed helps your dog settle and get up more comfortably.
- Access: ramps for the car or sofa save repeated jumping. Keeping nails trimmed helps grip too.
Keep a simple mobility diary
Jot down how stiff your dog is after rest, whether they hesitate at the stairs or the car boot, and how long they walk before slowing down. Photos or short videos are very useful for your vet. They also help you spot gradual change that is easy to miss from day to day.
When to see a vet
A supplement is not the right first step if your dog is showing signs of pain or a sudden change. Book an appointment if you notice limping that lasts more than a day or two or keeps coming back, swollen or tender joints, or marked stiffness after rest. The same goes for licking at a particular joint, or no improvement after you have started a supplement.
A puppy or young dog with an unusual gait, "bunny hopping" or difficulty rising should also be seen by a vet, as these signs are worth having checked early. Joint supplements are sometimes used in young dogs, but only on veterinary advice.
How quickly to call your vet
Mild stiffness after rest
Mention it at your next routine visit, keep a mobility diary, and ask whether a supplement suits your dog.
Recurring limp, reluctance on stairs, or licking at a joint
Book an appointment rather than waiting. Your vet can look for the cause and advise on next steps.
Sudden severe pain, collapse, or unable to stand
Contact your vet or an emergency clinic straight away. Do not wait to see if a supplement helps.
Your vet can diagnose the cause, recommend suitable care and advise whether a supplement such as Seraquin, Cosequin or MedPaw is right for your dog. Bring the pack or a photo of the label so they can see exactly what your dog is eating.
What is the main difference between Seraquin and Cosequin?
Both are described as containing glucosamine and chondroitin. From the manufacturer's information we reviewed, Seraquin Joint is a chewable tablet that also lists turmeric. The Cosequin overview describes a wider range, with some products including MSM, Boswellia, hyaluronic acid or omega-3, so the label on the exact product matters. Cosequin details came from a US-based overview, so please check the current UK label before you buy.
What does Seraquin Joint contain?
Seraquin Joint is a chewable tablet that lists glucosamine, chondroitin and turmeric. It does not list MSM, green-lipped mussel, hyaluronic acid, Boswellia, omega-3 or collagen. A guarantee is not stated in the information we reviewed, so check the manufacturer or retailer page.
Is Cosequin available in the UK in the same form as described?
The overview we looked at is US-based, so the range sold in the UK may differ. That is why we suggest checking the current label on any product you are considering, including which actives it lists and in what format. Your vet or the retailer can help if the label is unclear.
What should I look for when choosing between joint supplements?
Start with the label. Check which joint actives are listed and which are missing, the format your dog will actually eat, the daily amount for their weight and whether there is a loading period. Also look at whether a guarantee is stated, and mention your choice to your vet, especially if your dog takes any prescribed medication.
How does MedPaw Hip & Joint Chews Max compare with Seraquin?
MedPaw is a daily soft chew, a complementary feed, listing glucosamine, chondroitin, MSM, green-lipped mussel, hyaluronic acid and Boswellia serrata, plus omega-3. Seraquin is a chewable tablet listing glucosamine, chondroitin and turmeric, and turmeric is not in the MedPaw list. MedPaw offers a 60-day money-back guarantee, whilst Seraquin's is not stated in the information we reviewed.
My dog is stiff and I am not sure which supplement to pick. Should I see a vet first?
Yes, it is a sensible first step. Stiffness, a recurring limp or reluctance on stairs can have several causes, and a supplement is not a substitute for a diagnosis or veterinary care. Your vet can look for the cause and advise whether a supplement such as Seraquin, Cosequin or MedPaw suits your dog to support everyday mobility and comfort.
