The ingestion of styrofoam can be dangerous to dogs. How damaging it is to a dog’s health will depend on a number of factors such as the size and amount of styrofoam the dog ate.

What happens when a dog eats styrofoam

Some dogs may get lucky and nothing might happen after they eat some styrofoam. The dog, for example, may have only eaten one or two styrofoam peanuts. The pieces may have been small enough to pass along the dog’s intestinal tract without much issue.

Not all dogs will be lucky. Those that swallow a large piece of styrofoam may end up suffering from choking. The piece of styrofoam may partially block the dog’s air passage, making it difficult for the dog to breathe.

Styrofoam could also get stuck along the dog’s gastrointestinal tract. The stomach acids won’t dissolve it. The dog won’t be able to digest it. The styrofoam will becomes a major problem if it obstructs the path of the dog’s intestines. In such cases, surgery might be needed to extract the styrofoam out of the dog’s body.

What to do if your dog ate styrofoam

We wouldn’t leave it to chance. Call the vet as soon as you find out your dog has eaten styrofoam. The piece may not have gotten far inside the dog’s digestive system. If identified early enough, the vet can induce vomiting to get as many pieces out as possible.

In the meantime, keep a close eye on your dog and monitor their eating and pooping behavior. Any signs of strain and symptoms should be taken seriously, even if they appear mild. For example, it’s possible that the styrofoam is causing issues if your dog suddenly loses his appetite or is having a hard time defecating.
