My dog ate aluminum cans. What should I do if he swallowed pieces?

The biggest concerrn is that your dog may have not only chewed up but also swallowed pieces of the aluminum cans. Shards of aluminum cans can be quite sharp and can get stuck in the mouth, throat, esophagus, and intestines. Try to look inside your dog's mouth to see if there are any signs of cuts or pieces of can stuck in the mouth or throat. To help any pieces of aluminum pass through, you can give your dog something to bulk up the stools. Add 1 Tsp canned pumpkin per 10 lbs to its food, giving a bran muffin, or add 1 Tsp of Metamucil (for small dogs) or 2 Tsp of Metamucil (for large dogs) once or twice a day. Monitor your dog closely for the next 24-48 hours. If your dog starts to vomit, has diarrhea or doesn't not defecate, has a tender abdomen, or seems uncomfortable, then you will need to take your dog to your veterinarian.
