$11.5M Cosequin dog supplements class action settlement

Nutramax Laboratories agreed to pay $11.5 million as part of a class action settlement to resolve claims it misrepresented the benefits of its Cosequin supplements.

The Cosequin settlement benefits California residents who purchased 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/or Cosequin DS Maximum Strength Plus MSM Soft Chews between May 3, 2016, and May 6, 2022.

According to a class action lawsuit, Nutramax Laboratories misrepresents the benefits of its Cosequin dog supplements with claims that the product supports “mobility, cartilage and joint health” and “supports mobility for a healthy lifestyle.” In reality, the plaintiffs say, there is no scientific evidence that Cosequin provides these benefits but continues to make these claims to deceive consumers.

Nutramax Laboratories is a supplement company that sells products for humans and pets including Cosequin, a joint supplement for dogs.

Nutramax Laboratories has not admitted any wrongdoing but agreed to resolve these allegations with an $11.5 million class action settlement.

Under the terms of the Cosequin settlement, class members can receive a cash payment based on the number of units of Cosequin products they purchased. Class members can receive up to $25 per unit purchased, with a maximum payment of $150. Exact payments may be lower depending on the number of claims filed with the settlement.

In addition to providing cash benefits, Nutramax Laboratories has agreed to remove certain claims from its Cosequin packaging. The company will no longer claim that Cosequin supports “mobility, cartilage and joint health,” “supports mobility for a healthy lifestyle” or “use Cosequin to help your pet climb stairs, rise and jump!”

The deadline for exclusion and objection is June 22, 2026.

The final approval hearing for the class action settlement is scheduled for Aug. 13, 2026.

To receive settlement benefits, class members must submit a valid claim form by July 21, 2026.
