Milk-Bone class action overview:

  • Who: Plaintiff Melissa Burkett filed a class action lawsuit against Big Heart Pet Brands Inc.
  • Why: Burkett claims Big Heart Pet Brands falsely advertises its Milk-Bone Dipped dog treats as being free from artificial preservatives.
  • Where: The Milk-Bone class action lawsuit was filed in California state court.

A new class action lawsuit claims Big Heart Pet Brands falsely advertises its Milk-Bone Dipped dog biscuits as containing “no artificial preservatives, colors or flavors,” even though they contain manufactured citric acid, an artificial preservative.

Plaintiff Melissa Burkett filed the Milk-Bone class action complaint against Big Heart Pet Brands on July 2 in California Superior Court, alleging violations of state consumer laws.

According to the class action lawsuit, the packaging for Milk-Bone Dipped Biscuits prominently displays the claim that the products contain “no artificial preservatives, colors or flavors.”

However, Burkett says the dog treats actually contain manufactured citric acid, which is used as a preservative.

Burkett alleges that this misrepresentation is intended to give consumers the impression that they are buying a premium product for their pets.

Artificial citric acid involves genetic modification and chemical solvents, Milk-Bone lawsuit claims

Burkett states that the citric acid used in Milk-Bone products is not natural but rather a synthetic form derived from heavy industrial processing.

The class action lawsuit alleges that this form of citric acid is manufactured using a type of black mold called Aspergillus niger, which has been genetically modified to enhance citric acid production.

Burkett’s complaint includes detailed scientific explanations of how this citric acid is produced, arguing that the process is artificial and involves genetic modification and chemical solvents.

The Milk-Bone class action lawsuit also cites various studies and expert opinions to support the claim that manufactured citric acid is not natural and can cause adverse health effects in dogs, such as digestive upset and allergic reactions.

Burkett seeks to represent a class of all consumers who purchased the Milk-Bone Dipped products in California. She is suing for violations of California’s Consumers Legal Remedies Act, Unfair Competition Law and breach of express warranty.

Burkett is seeking certification of the Milk-Bone class action lawsuit, damages, restitution and an injunction to prevent Big Heart Pet Brands from continuing to market the Milk-Bone Dipped products as free from artificial preservatives.

In a string of similar lawsuits now targeting pet food manufacturers, pet owners have accused Post Consumer Brands of falsely advertising Rachael Ray pet food products as containing no artificial preservatives.

Burkett is represented by Craig W. Straub and Kurt D. Kessler of Crosner Legal P.C.

The Milk-Bone class action lawsuit is Burkett v. Big Heart Pet Brands Inc., Case No. 2:25-cv-07147, in the Superior Court of the State of California, Los Angeles County.

    I noticed very visible lumps growing on Daisy’s side and stomach. I started looking up Milk Bone Dog Treats which she has had for a couple months now. I have 2 boxes left but no way to return them to Walmart. I am 73 and disabled and I can’t get there. I received products from Walmart delivered by FedEx to my home. Daisy is 10 years old and just started having Milk Bone Dog Treats within the past year, and if I try to join a Class Action Lawsuit they will just say that she is ten years old and lots of older dogs get lumps. The Court system in California is totally corrupt. I filed a case many long years ago for being injured with explosives on a movie set and the attorneys lied and said they were harmless special effects. I took a law course at UCLA and a home correspondence paralegal course and I filed a complaint all by myself against State OSHA to bring in Federal OSHA and I got the Material Safety Data Hazard Sheets proving they injured me with Lead Azide, Lead Styphnate and PETN, all three federally regulated toxic hazardous substances. Right when I should have won, my case was dismissed and denied. Years later I found out the U.S. Senator Patrick Leahy of Vermont had been taking political campaign donations from the attorneys for the movie industry.

Chip [Chocolate Chip, named by his first best friend whom I would love to thank once again for allowing me to Adopt Chip. We had to have him put to sleep at 14 years and 9 months old only because we decided not to put him thru any surgeries that would have been devastating to him , to not allow him to run, jump and play. Chip was 142lbs, truly only about 10 pounds over but that’s not here nor there . I’m getting choked up 15 yrs later stil. From the day I got home with him until his dying day, he only got two brands of dog food and his treats 95% of his almost 15 years, one sec doing thr math on my toes and fingers 👉 👈 yep that’s is 2.918 to the 16th degree of the… got that so far??
