Cosequin and Dasuquin are both made by Nutramax Laboratories and are among the joint supplements vets recommend most often. They share a base of glucosamine and chondroitin. The main difference is that Dasuquin adds ASU. Here is how to choose. Always ask your veterinarian before starting a supplement, especially if your dog takes medication or has a health condition.
The short answer
- Cosequin: glucosamine + chondroitin (some versions add MSM). Lower price. A good starting point for mild stiffness or prevention.
- Dasuquin: glucosamine + chondroitin + ASU (avocado/soybean unsaponifiables). Higher price. Often suggested for dogs with established arthritis or when Cosequin alone has not been enough.

What ASU adds
ASU is a blend of compounds extracted from avocado and soybean oils. Lab studies suggest it may support cartilage and work alongside glucosamine and chondroitin, but clinical evidence in dogs is still limited. That is why Dasuquin is usually seen as a step up rather than a different product category.
Which one should you choose?
- Young or middle-aged dog, early stiffness, or prevention: Cosequin is a sensible, cheaper start.
- Diagnosed arthritis, older dog, or no change after 6 to 8 weeks on Cosequin: ask your vet about Dasuquin.
- Either way, consider adding a vet-dosed omega-3 fish oil, which has stronger evidence than either product’s core ingredients.
How they compare with newer brands
Newer chews such as Wuffes combine glucosamine with green-lipped mussel, hyaluronic acid and other ingredients. Nutramax products have a longer track record and are often the default recommendation in vet clinics. See our best dog joint supplements guide for the full comparison.
