Cosequin $11.5M Dog Joint Supplement Class Action Settlement

California residents who bought a covered Cosequin dog joint supplement (chewable tablets or soft chews) for personal use between May 3, 2016 and May 6, 2022. No receipt needed — you just state how many units you bought.

• Lived in California during the purchase period
• Bought a covered Cosequin DOG product (tablets or soft chews) between May 3, 2016 and May 6, 2022
• Purchased for personal use, not resale
• One claim per household

Nutramax Laboratories agreed to an $11.5 million settlement to resolve claims that it falsely marketed its Cosequin dog supplements as supporting joint health, mobility, and cartilage — with claims like "Supports Mobility for a Healthy Lifestyle" and "help your pet Climb stairs, Rise and Jump!" The lawsuit argued that peer-reviewed studies found no evidence that Cosequin's active ingredients (glucosamine and chondroitin) actually improve joint health in dogs. One study published in the British Medical Journal's Vet Record found dogs receiving the supplement showed "no significant response" in gait analysis. Nutramax denies wrongdoing and settled to avoid the cost of continued litigation.

Who's excluded: Cat products are not covered — only dog Cosequin products. Residents of states other than California, and anyone who bought for resale or business use, are not included.

  Up to a maximum of $150 per household (6+ units = the full $150). One claim form per household. No receipt or proof of purchase required — you state how many units you bought. If total valid claims exceed the fund after fees, payments may be reduced pro rata.
