5 lb Maltese you came home and she had gotten into a travel size pack of Parmesan Cheese The paper was coated on the inside with aluminum foil She ate some Should you be worried?

In short, probably not. The foil is non-toxic, and will likely pass just fine through her tiny gastrointestinal tract, but you never know. I have treated patients who ate shaving safety razors which passed fine, and patients who have died from a tiny fruit pit which got stuck in their intestines. I have never seen foil wrapping cause a problem. The cheese will likely just cause some stomach and intestinal upset--likely limited to diarrhea, possibly vomiting. In rare cases, single large ingestions of unfamiliar food, especially fatty foods, can cause a life-threatening disease called pancreatitis. Profuse vomiting and or diarrhea can become life threatening. You should watch your dog, and if she shows any of those signs, bring her to your vet. If she begins vomiting or having bad diarrhea when your vet is closed, go to an emergency clinic at night.
