Purina dog food has been in the news recently regarding concerns about their product Purina Beneful. There has been a class-action lawsuit that this particular dog food is killing dogs. The present claim is that Purina Beneful contains propylene glycol, an automotive antifreeze component, and mycotoxins, toxins produced by a fungus that can be found in contaminated grains according to multiple articles about the lawsuit. Propylene glycol is also a food preservative commonly used in human foods. Ethylene glycol is the toxic agent in antifreeze that causes kidney failure. While mycotoxins are produced by certain types of fungus that can be found on grains, there is currently no proof that the grains in Purina’s Beneful were contaminated with any fungus, let alone the type that produces mycotoxins. While Purina’s Beneful isn’t a top-tier food, there are no signs that it isn’t safe for dogs to eat. Any food can become contaminated with potentially damaging ingredients, but many large dog food companies (such as Hill’s Science Diet, Purina, Iams, and Eukanuba) have such high standards with food safety that problems are rare. Still concerned? Feel free to change your dog’s diet. Make sure to slowly change over 5-7 days to avoid GI upset (signs include vomiting and diarrhea). If your dog is eating Purina Beneful and you are seeing any vomiting, diarrhea, weight loss, bloat, or seizures, please contact your veterinarian to schedule an exam immediately.
