What happens if a dog eats aluminum foil?

When a dog eats aluminum foil, the outcome varies depending on the amount eaten and the dog's size. Sometimes, the foil passes through the digestive tract without any issues. In other cases, foil causes a blockage, and a trip to the vet is in order.

Large dogs who have eaten a small amount of aluminum foil are usually able to pass it without any problems. Complications are more common in smaller breeds and when large amounts are consumed. Signs to watch for include vomiting, diarrhea, refusal to eat or drink, and excessive drooling. When any of these symptoms are present, urgent veterinary care is required.
