According to the 16-page lawsuit, independent testing performed by Consumer Reports in February 2025 revealed that the kibble variety contains vitamin D at levels 4.8 times the maximum amount permitted by the Association of American Feed Control Officials (AAFCO).

The complaint says that dogs who ingest pet food with too much vitamin D can develop vitamin D toxicity, which may result in diarrhea, vomiting, lack of appetite, increased drinking and urination, excessive drooling, weight loss and even death.

The suit accuses the maker of Pedigree kibble, Mars Petcare US, Inc., of falsely advertising the product as a “100% Complete & Balanced” diet for dogs. Indeed, Pedigree Complete Nutrition Roasted Chicken & Vegetable Dog Kibble fails to meet the AAFCO’s nutritional profile for “complete and balanced” pet food due to its excessive vitamin D content, the case argues.

“Reasonable consumers believe, based on the Nutrition Claim, that the Contaminated Kibble would contain all the nutrients required for their pets and that those nutrients would be present in amounts suitable for their pets,” the filing contends.

The Pedigree lawsuit was filed by two consumers who say they purchased the pet food under the belief that it was nutritionally balanced and suitable as the sole diet for their dogs. The plaintiffs claim, however, that the Pedigree kibble contained undisclosed, elevated vitamin D levels that caused their dogs to vomit and have diarrhea after consuming the food as directed.

“Had [Mars] not breached the express warranty by making the false representations alleged herein, [the plaintiffs] and the Class Members would not have purchased the Contaminated Kibble or would not have paid as much as they did for them,” the complaint claims.

The lawsuit looks to represent all United States residents who purchased Pedigree Complete Nutrition Roasted Chicken & Vegetable Dog Kibble during the applicable statute of limitations period.
