California residents who bought Cosequin dog joint supplements (May 2016 – May 2022) filed 1,092,841 claims by the July 21, 2026 deadline. The court granted final approval of the $11.5 million settlement on November 3, 2026; payments wait for the appeal period to end, and no payment date is set.
Cosequin Settlement Status Update
Final approval was granted on November 3, 2026. The court entered its final approval order on November 3 and closed the case, according to the federal docket. Judge Fernando M. Olguin had held the final approval hearing on August 13, 2026 without ruling from the bench. He ordered the parties to file declarations by August 28 disclosing any side agreements and giving the administrator's final claim count and claims rate. Those were filed on August 28, and the court allowed parts of the administrator's declaration to be sealed on August 31. The November 3 order followed those filings.The administrator, Epiq, reported 1,092,841 claim forms as of August 27, 2026 (1,091,650 online and 1,191 on paper). Epiq screened claims against 15 fraud categories and denied those with significant signs of fraud; the exact numbers are sealed. No class members objected and none opted out.
Payments go out 30 days after the Final Effective Date, which is final approval plus the end of the appeal period. Federal appeals are generally due within 30 days of judgment, so if no one appeals, payments could follow in early 2027. No payment date has been announced.

What Is the Cosequin Settlement About?
A class action has been settled over allegations that Nutramax Laboratories falsely marketed its Cosequin dog supplements as promoting joint health, mobility, and cartilage support. Cosequin products were advertised with claims like "Mobility, Cartilage and Joint Health Support," "Supports Mobility for a Healthy Lifestyle," and "Use Cosequin to help your pet Climb stairs, Rise and Jump!".The class action lawsuit argued that peer-reviewed scientific 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 VetRecord found that dogs receiving Cosequin showed "no significant response" in gait analysis or subjective assessments, and owners reported "no significant improvements."
