Cosequin Dog Joint Supplement $11.5 Million Class Action Settlement 2026 — Up to $150
By Steve Levine
Published: March 9, 2026
Claim Deadline: July 21, 2026
Payout: Up to $150 per household ($25 per unit purchased)
Proof required: No
A new open 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."
