The $11.5 million Nutramax class action settlement received preliminary approval from the court on February 2, 2026 and covers all individuals residing in California who purchased any of the following Cosequin canine products for personal use between May 3, 2016 and May 6, 2022:

• -Cosequin DS Maximum Strength Chewable Tablets;
• -Cosequin DS Maximum Strength Plus MSM Chewable Tablets;
• -Cosequin Maximum Strength Plus MSM Chewable Tablets;
• -Cosequin with MSM Chewable Tablets;
• -Cosequin Maximum Strength Plus MSM Soft Chews;
• -Cosequin with MSM Soft Chews; and
• -Cosequin DS Maximum Strength Plus MSM Soft Chews.

The court-approved website for the Cosequin class action settlement can be found at CosequinCASettlement.com.

According to the website, Cosequin settlement class members who submit a valid, timely claim form are eligible to receive up to $25 per Cosequin product purchased for up to six products, for a maximum payout of up to $150. Importantly, the settlement agreement reports that payments will be issued per household, not per class member.

The settlement agreement outlines that if the total value of all valid claims exceeds the amount remaining in the net settlement fund after payment of attorneys’ fees and lead plaintiff service awards, payments to class members may be subject to a pro-rated reduction.

The agreement additionally notes that any money left over after payments to class members have been sent will be distributed as a cy pres award to Valor Service Dogs.

Class members can receive their payout via check or electronic payment; the agreement adds that all checks must be cashed within 90 days of issuance before expiration.

To file a Cosequin settlement claim form online, class members can head to this page and fill out all required fields with relevant information. Alternatively, class members may download a PDF claim form from the settlement site to print, fill out and return by mail to the address of the settlement administrator listed on the first page of the document.

All Cosequin settlement claim forms must be submitted online or by mail by July 21, 2026.

Finally, as part of the settlement, Nutramax has agreed to remove the following statements from any future Cosequin packaging: “Mobility, Cartilage and Joint Health Support,” “Supports Mobility for a Healthy Lifestyle,” and “Use Cosequin to help your pet [c]limb stairs, [r]ise and [j]ump!” The agreement notes that Nutramax, however, may continue to plainly use the statement “Joint Health Supplement” on Cosequin products.

The court will determine whether to grant final approval to the Nutramax settlement following a hearing on August 13, 2026. Compensation will begin to be distributed to class members only after final approval is granted and any appeals are resolved.

The Nutramax class action lawsuit claimed that the supplement company misleadingly and falsely advertised certain claims about its Cosequin canine supplements—including enhanced joint flexibility, mobility and restored joint health—that they were allegedly incapable of providing in violation of the California Consumers Legal Remedies Act and a host of state-specific consumer protection laws.
