Cosequin Settlement Status Update
Final approval has not been granted yet. Judge Fernando M. Olguin held the final approval hearing on August 13, 2026 but did not rule. 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. As of the latest docket entry on September 1, 2026, there is no final approval order and no final judgment.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 will not go out until 30 days after the Final Effective Date — final approval plus the end of the appeal period — so no payment date is set. Read more in our Cosequin settlement status update.
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."
