What happened
Plaintiffs Justin Lytle and Christine Musthaler filed this class action against Nutramax Laboratories, Inc. and Nutramax Laboratories Veterinary Sciences, Inc. alleging the companies misrepresented the benefits and effectiveness of certain canine Cosequin supplements in both advertising and on product packaging. The lawsuit covers seven Cosequin-branded dog supplements purchased for personal household use in California between May 3, 2016 and May 6, 2022.
Nutramax denies the allegations and denies any wrongdoing or liability, and the Court has not made any determination that Nutramax violated any law. The parties agreed to settle to avoid the cost, risk, and time of continued litigation. As part of the Settlement, Nutramax also agreed to remove three claims from future Cosequin packaging: “Mobility, Cartilage and Joint Health Support”; “Supports Mobility for a Healthy Lifestyle”; and “Use Cosequin to help your pet Climb stairs, Rise and Jump!”

Where the money is going
This is a non-reversionary common fund. Attorneys’ fees, service awards, and the Fee and Expense Award come out of the $11.5 million before payments are calculated for class members.
All amounts listed above are pending and subject to final court approval at the Fairness Hearing. The Court may award less than the amounts requested. If valid claims exceed what remains of the fund, payments will be reduced on a pro rata basis.
Common questions
How much money will I receive?
Each valid claim is paid at $25 per unit of qualifying Cosequin product purchased between May 3, 2016 and May 6, 2022, up to a maximum of $150 per Household. If the total of all valid claims is greater than what remains of the $11.5 million fund after attorneys’ fees, costs, and service awards, the Settlement Payment for each Class Member will be reduced on a pro rata basis. Actual payments may therefore be less than $25 per unit depending on claim volume.
Do I need to submit proof of purchase?
The public Notice and FAQ on the settlement website do not state that documentation is required to submit a Claim Form. The Notice does limit each Household to a single Claim Form and caps recovery at $150 per Household. Note that excluding yourself from the Settlement (opting out) does require proof that you purchased a Cosequin product during the class period. Review the Claim Form at CosequinCASettlement.com/Claim for any additional verification fields.
What if I didn’t receive a notice?
You can still file a claim even if you did not receive a direct notice. Notice in this case was distributed primarily by publication and online, since Nutramax did not have direct customer records for retail purchasers. If you bought one of the seven qualifying Cosequin products in California during the class period, you are likely a Class Member and can submit a Claim Form. For help, visit CosequinCASettlement.com or call the Settlement Administrator toll-free at 1-888-899-7783.
Does staying in the class affect my right to sue later?
Yes. Unless you opt out by mailing a written exclusion request postmarked by June 22, 2026, you will be bound by the Settlement and you will release the legal claims at issue in this lawsuit against Nutramax and the other Released Parties. That means you cannot sue Nutramax separately about the same alleged misrepresentations. The full release language is in Section 9 of the Settlement Agreement, available at CosequinCASettlement.com.
When will payments be sent out?
The Court will hold the Fairness Hearing on August 13, 2026 at 10:00 a.m. before Judge Fernando M. Olguin in Los Angeles. Payments will only be issued after the Court grants final approval and any appeals are resolved. The appeal process can take a year or more. No action is required after a valid Claim Form is submitted, just check CosequinCASettlement.com for updates.
