Overview

Dasuquin with MSM is the step-up from Cosequin, made by the same company, Nutramax. It keeps the glucosamine, chondroitin and MSM base but adds avocado/soybean unsaponifiables (ASU), boswellia and green tea extract. Nutramax cites cell-culture research on combining ASU with glucosamine and chondroitin, and describes Dasuquin as the number one veterinarian-recommended joint health supplement brand, based on its own survey.

This listing is the large-dog version, meant for dogs 60 lb and over. Nutramax makes a separate small and medium formula for dogs under 60 lb, so check which one you are buying.

Key features

Per large-dog tablet: glucosamine HCl 900 mg, MSM 800 mg, chondroitin 350 mg
Adds ASU 90 mg, boswellia 40 mg and green tea extract 32 mg
For dogs 60 lb and over; separate formula for smaller dogs
84 chewable tablets
Made in the USA with globally sourced ingredients

Who it suits (and who should skip it)

It suits large and giant breeds, seniors and very active big dogs where your vet has suggested a more comprehensive joint formula. Owners who want one product instead of stacking several joint ingredients may also prefer it.

Skip it if your dog is under 60 lb, since this is the wrong size formula. Skip it, too, if you want a product with a confirmed Canadian NN on the label. The Health Canada NN we found for Dasuquin with MSM belongs to the soft chew version for large dogs, not these chewable tablets, and we could not find one for the tablet. As with Cosequin, Nutramax is not a NASC member. Any new or sudden limping needs a vet check before a supplement.

Because Dasuquin and Cosequin share a maker, moving from one to the other is a common vet suggestion as a dog’s needs change with age. Bring the box to appointments so your vet can see the exact formula and per-tablet amounts, and mention any other supplements your dog already takes.

Costs to know about

Dasuquin is a daily, ongoing supplement and costs noticeably more per day than Cosequin. How long an 84-count box lasts depends on your dog and your vet’s advice; follow the label.

Counterfeit risk is real. Nutramax has warned about fake Dasuquin from unauthorised third-party sellers, and look-alike listings appear on Amazon.ca. Buy from the listing shipped and sold by Amazon, check that the title says Large Dogs and 84 chewable tablets, and inspect the seal and lot number on arrival.

How it compares

Cosequin DS Plus MSM is the simpler, cheaper option with a Health Canada NN on its Canadian label, and it suits many dogs well. Dasuquin is the one to discuss with your vet if you want the added ASU, boswellia and green tea extract or higher per-tablet amounts for a big dog. Joint support also depends on body weight, so a measured, complete diet such as Purina Pro Plan Sensitive Skin & Stomach is part of the same picture.

Frequently asked questions

What is the difference between Dasuquin and Cosequin?

Both are Nutramax joint supplements built on glucosamine, chondroitin and MSM. Dasuquin adds avocado/soybean unsaponifiables (ASU), boswellia and green tea extract, and the large-dog tablet has higher per-tablet amounts. Cosequin is simpler and cheaper. Your vet can tell you whether the extra ingredients are worth it for your dog.

Can I give the large-dog Dasuquin to a smaller dog?

This formula is labelled for dogs 60 lb and over. Nutramax sells a separate small and medium version for dogs under 60 lb, which is the one to look for if your dog is lighter. Follow the label and ask your vet before using any joint supplement outside its stated weight range.

Does Dasuquin have a Health Canada NN number?

We found Health Canada NN.B5O5 on the Canadian label of Dasuquin with MSM soft chews for large dogs. We did not find an NN for the chewable tablets in this listing, so we do not claim one. If an NN on the label matters to you, check the package you receive or ask your vet clinic about the soft chews.

Is Dasuquin sold on Amazon genuine?

It can be, if you buy carefully. Choose the listing shipped and sold by Amazon, confirm the title says Large Dogs and 84 chewable tablets, and avoid look-alike third-party listings. Nutramax has warned about counterfeits from unauthorised sellers, so check the seal, lot number and expiry date when it arrives.
