Nutramax Dasuquin with MSM for Dogs is a veterinarian-recommended joint health soft chew from Nutramax Laboratories Veterinary Sciences that combines glucosamine hydrochloride (600–900 mg per chew), chondroitin sulfate, ASU (avocado/soybean unsaponifiables), and MSM (400–800 mg per chew) to help support cartilage and comfortable joint mobility in dogs. The ASU works with glucosamine and chondroitin to help protect cartilage from breakdown, going beyond standard glucosamine/chondroitin supplements.

Frequently asked questions
What does Dasuquin with MSM do for dogs?
It helps support cartilage production, helps protect existing cartilage from breakdown, and supports joint comfort and mobility using glucosamine, chondroitin, ASU, and MSM.
What is the difference between Dasuquin and Dasuquin with MSM?
Both contain glucosamine, chondroitin, and ASU; the MSM version adds 400–800 mg of methylsulfonylmethane per chew for additional joint support.
How long does Dasuquin take to work?
Nutramax recommends allowing 4–6 weeks of the initial administration period to note a response, though some dogs respond sooner.
What is the difference between Dasuquin and Cosequin?
Cosequin provides glucosamine and chondroitin; Dasuquin builds on that base by adding ASU, which works synergistically to help protect cartilage. See Cosequin DS Chewable Tablets.
