Blue Buffalo Co. went on the offensive Wednesday against Nestlé Purina PetCare, accusing the company of false advertising and unfair competition.
The Connecticut-based company filed a federal lawsuit claiming St. Louis-based Nestlé Purina has been making false statements about Blue Buffalo’s pet food.
The ongoing strife between the two companies started last week when Purina filed a lawsuit accusing Blue Buffalo of lying to customers about its use of natural ingredients.
In its own lawsuit, filed in U.S. District Court in St. Louis, Blue Buffalo said it was trying to “stop a sophisticated and carefully orchestrated advertising campaign by its competitor Nestlé Purina that falsely attacks Blue Buffalo’s honesty and the quality of its products.”
Purina says Blue Buffalo is using chicken byproducts and corn in its pet food, despite claims to the contrary.
Blue Buffalo maintains that it does not use those ingredients.
