The Question
“Hi Dr. Paola,
My dog Luna passed away shortly after I changed her dog food. Is it possible to get her food tested? Because if it was the cause, it should probably be a recall and I could save other dogs. ” – Amber
Quick Info about Luna

Amber, I am so sorry for your loss. Losing Luna must be incredibly painful, and I can only imagine how difficult it is to navigate this while wondering if her food played a role. Your concern for other dogs speaks volumes about your love for animals, and you absolutely can have her food tested to rule out any potential contamination or toxicity.
To do this, you’ll want to keep the remaining food stored in its original packaging, if possible, as the lot number, expiration date, and manufacturer details will be important. A veterinary toxicology lab or a university-affiliated diagnostic lab would be the best place to test for contaminants like mold toxins, bacterial pathogens, heavy metals, or unexpected drug residues. You may also want to report your concern to the FDA’s Center for Veterinary Medicine, as they track potential pet food issues. If Luna’s passing was sudden and unexplained, a necropsy (animal autopsy) performed by a veterinary pathologist could provide clarity, in finding the cause of death.
While it’s natural to look for answers, please try to remain calm during this time. Food-related deaths in dogs are rare, but they do happen, and if the food was the issue and other dogs are saved, that would be a meaningful way to honor your Luna.
Condolences,
Dr. Paola
