Blue Buffalo faces class action over grain-free dog food claims

A proposed class action lawsuit has been filed against Blue Buffalo by an Illinois family who allege the company’s grain-free dog food contributed to their Goldendoodle’s dilated cardiomyopathy, or DCM, and death. Reporting on the case says the suit was filed in federal court and argues Blue Buffalo marketed grain-free formulas as healthy and premium despite years of scrutiny around possible links between some grain-free, pulse-heavy diets and diet-associated DCM in dogs. The case revives a long-running controversy that first drew national attention when the FDA opened its investigation in 2018. (petfoodindustry.com)

Why it matters: For veterinary professionals, this lawsuit lands in a clinically unsettled area that many practices still navigate with pet parents every day. The FDA has said adverse event reports alone are not enough to prove causation, but it has also documented reports involving grain-free diets with high proportions of peas, lentils, and potatoes. That means clinics may see renewed questions about diet history, screening for suspected diet-associated DCM, and how to counsel pet parents on grain-free products without overstating what the evidence does, or doesn’t, show.

What to watch: Watch for Blue Buffalo’s response, any motion practice around class certification, and whether the case prompts broader industry messaging or new discussion of diet-associated DCM guidance. (petfoodindustry.com)
