Does Nutramax Cosequin for Dogs actually help a dog with stiff joints? Nutramax describes it as joint health support with ingredients backed by scientific research. Published studies on those ingredients do not all agree, and a supplement does not replace a vet’s diagnosis. This review covers the ingredients, the amount to give, the evidence, and who it suits.
Amazon lists it as Nutramax Cosequin Joint Supplement for Dogs, MSM+HA, Chew Tablets, 150ct. The brand’s own name for it is Cosequin Joint Health Supplement for Dogs, Chewable Tablets with Glucosamine, Chondroitin, MSM, and HA.
Each chewable tablet contains glucosamine hydrochloride, sodium chondroitin sulfate, MSM, hyaluronic acid (HA), and manganese. According to the brand, it supports joint health in dogs of any breed or size, young or senior. Nutramax describes Cosequin as the number 1 veterinarian recommended retail joint health supplement brand, based on a survey among small animal veterinarians who recommended oral joint health supplements.
One point to settle early. This is a joint health supplement. It is not a pain medication and should not replace veterinary diagnosis or treatment for arthritis, injury, or another painful condition. A dog that is limping or in pain needs a vet to find the cause first.

What Is in Each Tablet
The Amazon listing names the main ingredients. The amounts below come from Nutramax’s own product page, checked in October 2026. Labels are updated over time, so the panel on your own bottle is the one to go by.
| Ingredient | Amount per Tablet |
|---|---|
| Glucosamine hydrochloride (FCHG49) | 600 mg |
| Sodium chondroitin sulfate (TRH122) | 300 mg |
| Methylsulfonylmethane (MSM) | 250 mg |
| Hyaluronic acid (HA), listed by the brand as sodium hyaluronate | 6 mg |
| Manganese, as manganese ascorbate | 3 mg |
Glucosamine and chondroitin are the 2 main ingredients. The codes FCHG49 and TRH122 are Nutramax’s own names for its versions of them. The brand says they help support a dog’s cartilage, the connective tissue that cushions a joint.
MSM is short for methylsulfonylmethane. According to the brand, it provides sulfur, which helps support joint health.
Hyaluronic acid is what sets this version apart. The brand describes it as a major component of joint fluid that helps keep joints moving smoothly. Sodium hyaluronate, the name on the brand’s page, is a salt form of hyaluronic acid.
Manganese is also listed on the brand’s page, at 3 mg per tablet.
The brand describes these as ingredients backed by scientific research. The Amazon listing adds that every batch undergoes thorough quality inspections. The one benefit named on the listing is joint health. Those are the brand’s statements. They are not medical claims made by this review.
Versions and Sizes
Cosequin comes in several versions, and the names are close enough to mix up. The Amazon listing offers 2 styles, MSM and MSM with HA. With the MSM and HA style selected, it shows 2 sizes, 75 and 150 tablets. The MSM style comes in its own sizes, and the 60 tablet bottle in the table below is one of them.
| Version | What Differs | Link |
|---|---|---|
| Cosequin with MSM and HA, 150 tablets | The version reviewed here. Includes hyaluronic acid | Check price on Amazon |
| Cosequin with MSM, 60 tablets | No hyaluronic acid. A smaller bottle for owners who want to try this version | Check price on Amazon |
According to the brand’s page for the MSM tablets, that version has the same 600 mg of glucosamine, 300 mg of chondroitin, and 250 mg of MSM per tablet. The difference is the hyaluronic acid.
The name varies too. Nutramax’s web address for this version still carries the name Maximum Strength Plus MSM and HA, so that name points to the same product.
Other Cosequin products include Cosequin DS chewable tablets, soft chews with omega-3, and a capsule for small dogs and cats. Each has its own directions. Dasuquin is a separate Nutramax joint supplement with its own formula, so Cosequin vs Dasuquin is a question for a vet.
The listing shows a per-tablet price for each size, which is the quickest way to see which is cheapest on the day.

Who It Suits
A Reasonable Fit For
- Dogs whose vet has suggested a joint supplement
- Young and senior dogs, which the brand names among the dogs it is made for
- Large breeds, which the brand also names. Our own breed guides cover large dogs such as Labrador Retrievers, German Shepherds, and Rottweilers
- Owners who prefer a chewable format, which the brand describes as tasty
- Homes with small, medium, and large dogs, since the dosing chart covers every weight
When to Involve a Veterinarian
- A dog that is limping, lame, or in pain with no diagnosis yet should see a vet first
- Dogs with hip dysplasia, arthritis, another diagnosed joint condition, or recent joint surgery should use supplements as part of a vet-guided care plan
- Dogs taking medication or living with a health condition should check with a vet before adding a supplement
- Dogs with a known food allergy should have the ingredients confirmed with Nutramax or a vet first
- A dog that needs pain relief should see a vet. This is a supplement, not a pain medication
- This version is for dogs. Ask a vet before giving it to a cat
Prescription veterinary drugs such as Rimadyl (carprofen), Galliprant (grapiprant), and Adequan are a different category from a nutritional supplement and may be used under veterinary supervision for joint disease or pain. Cosequin should not be used as a substitute for veterinary treatment when a dog needs prescription therapy.
How Much to Give
The Amazon listing refers buyers to the package for directions. The dosing chart below is from Nutramax’s product page. It goes by the dog’s weight, with a higher daily amount for the initial 4 to 6 weeks and a lower one after the initial 6 weeks.
| Dog’s Weight | Initial 4 to 6 Weeks | After the Initial 6 Weeks |
|---|---|---|
| Up to 15 lb | Half a tablet a day | Half a tablet every other day |
| 16 to 30 lb | 1 tablet a day | Half a tablet a day |
| 31 to 60 lb | 2 tablets a day | 1 tablet a day |
| Over 60 lb | 3 tablets a day | 1 to 2 tablets a day |
Follow the directions on your own bottle if they differ, and ask a vet about the right amount for a dog with a health condition.
How long a bottle lasts. It depends on the dog’s size. For a dog of 31 to 60 lb, 150 tablets are a 75 day supply at the starting amount or a 150 day supply at the later amount. For a dog over 60 lb, the same bottle covers 50 days at the starting amount.
Owners who buy online should check that the seal is intact and look at the expiration date on the bottle when it arrives.
What to Expect
The brand’s directions use a higher amount for the initial 4 to 6 weeks, then a lower amount after the initial 6 weeks.
Some dogs may experience digestive upset after starting a supplement. If your dog develops vomiting, diarrhea, or another concerning reaction after starting Cosequin, contact your veterinarian.
Published research on glucosamine and chondroitin in dogs does not all agree. Some trials have reported improvement. The Merck Veterinary Manual notes a review of the evidence that did not find support for these supplements in managing osteoarthritis pain.
That evidence concerns clinical pain management. Nutramax markets Cosequin for joint health support, not as a pain medication, and for a dog in pain a vet’s view comes first.
A tablet is one part of joint care. The Merck Veterinary Manual describes keeping a dog at a healthy weight as the primary way to slow the development of osteoarthritis.
Bedding is a separate topic, which our review of the FurHaven orthopedic dog bed covers.
When to See a Vet First
See a vet before trying any supplement if a dog is suddenly lame, will not put weight on a leg, cries out when touched, shows swelling or inflammation in a joint, has trouble getting up, can no longer climb the stairs, or has stiffness that keeps getting worse. Joint problems have many possible causes, so a supplement cannot determine the underlying cause.
Nutramax Cosequin for Dogs FAQ
Does Cosequin really work for dogs?
It depends on the dog’s condition. Nutramax describes Cosequin’s ingredients as backed by scientific research and markets it for joint health support. Published studies on glucosamine and chondroitin in dogs do not all agree. Whether it is worthwhile for a particular dog is best discussed with a veterinarian.
How long does Cosequin take to work?
The product directions use a higher daily amount during the initial 4 to 6 weeks and a lower amount after the initial 6 weeks. That schedule is about how much to give. It is not a statement of when a dog will respond. Published studies on glucosamine and chondroitin in dogs do not all agree, so ask your veterinarian how to judge whether it is helping your dog.
How much Cosequin should I give my dog?
It goes by weight. For the initial 4 to 6 weeks, the brand’s amounts are half a tablet a day up to 15 lb, 1 tablet for 16 to 30 lb, 2 tablets for 31 to 60 lb, and 3 tablets over 60 lb. The amount drops after the initial 6 weeks.
What is the difference between Cosequin with MSM and with MSM and HA?
Hyaluronic acid. According to the brand, both versions have 600 mg of glucosamine, 300 mg of chondroitin, and 250 mg of MSM per tablet. The MSM and HA version adds 6 mg of hyaluronic acid.
Can puppies take Cosequin?
Nutramax describes the product for young and senior dogs. For a puppy, ask your veterinarian before use, since a growing puppy’s needs differ from an adult dog’s.
Does Cosequin have side effects?
Some dogs may experience digestive upset after starting a supplement. If you see an adverse reaction such as vomiting or diarrhea after starting Cosequin, contact your veterinarian.
Does Cosequin contain shellfish, chicken, or another allergen?
The product page lists the ingredients and amounts shown above. In our research, we did not find the flavor or the source of each ingredient named there. For a dog that is allergic to shellfish, chicken, or another protein, confirm the current ingredient and source information with Nutramax or your veterinarian before use.
Can a dog take Cosequin long term?
The brand’s directions give a higher amount for the initial 4 to 6 weeks and a lower amount after the initial 6 weeks, without specifying a stopping date. For long term daily use, discuss continued use with the vet who knows the dog.
What if my dog eats too many Cosequin tablets?
Treat any possible overdose as a question for a vet. Call a vet or an animal poison control line right away and have the bottle to hand. For safety, store the bottle out of a dog’s reach, since the tablets are made to taste good.
Is Cosequin a pain medication?
No. It is sold as a joint health supplement. A dog in pain needs a vet, who can find the cause and decide whether medication is needed.
Can I give this Cosequin to my cat?
This version is for dogs. The listing gives the directions and the breed sizes for dogs only. Ask a vet before giving any dog supplement to a cat.
Where is Cosequin made?
According to the brand, it is made in the United States with globally sourced ingredients. The manufacturer is Nutramax Laboratories.
