Parmesan cheese is not toxic to dogs, but the foil packaging can be dangerous if ingested. Foil can cause an obstruction in the dog's digestive tract, which can lead to vomiting, diarrhea, and abdominal pain. In severe cases, foil can also cause the dog to become dehydrated and develop a fever.
If you think your dog has eaten foil, it is important to take her to the vet immediately. The vet will be able to confirm whether or not the foil has caused an obstruction and will recommend the best course of treatment.
In the meantime, there are a few things you can do to help your dog:
* Offer her small amounts of water to drink.
* Feed her a bland diet of boiled chicken and rice.
* Monitor her for any signs of vomiting, diarrhea, or abdominal pain.
* If she develops any of these symptoms, take her to the vet immediately.
With prompt treatment, most dogs who have eaten foil will recover without any problems.
