This article will discuss what should be done if your dog eats Styrofoam, how dangerous it is, and how to keep your pet safe.

Let us start the article by knowing what actually is a styrofoam.

What is Styrofoam?

What is Styrofoam?

Styrofoam is a foam made out of solid beads of polystyrene, which is a type of plastic that is mainly used for packaging works. It comes in various sizes and shapes and is used to provide support to a packaged product.

Many toys, including pet toys, couches, dog beds, and bean bags, have Styrofoam inside them. And all these things are the favorite things to chew; if not paid attention to them, they will chew the toys and probably eat some styrofoam which can be harmful.

Some companies use Styrofoam to package a lump of meat. When your pooch sees that a lump of meat comes in those styrofoam trays, cups, and plates, they will want to eat it as it may taste as tastier as meat.

And it is very commonly found everywhere. When you take your canine partner on a jog, keep an eye on them as they may find some on the street and wanna chew it.

What Happens if a Dog Eats Styrofoam?

What Happens if a Dog Eats Styrofoam?

Like all inedible substances, when a dog eats Styrofoam, smaller pieces tend to digest through the metabolism and excrete through feces in two to three days in small quantities as the digestion happens with no major repercussions.

The risk is always to smaller breed dogs; when their throat, including all other organs and internal systems, is small, Styrofoam gets stuck somewhere in between, resulting in the blockage of guts.

But if a larger piece or a lot of small pieces of Styrofoam is ingested by a dog, irrespective of breed, be it smaller or larger, it will cause a gastrointestinal blockage.

In extreme cases, if a dog’s system is not able to digest the Styrofoam or any plastic-made material, chances are the kidneys and livers will collapse too.

The more it stays in a dog’s system, the more damage it will do, as it will keep on releasing the toxic chemicals that Styrofoam is made of.

Apart from various organ failures, these chemicals released from Styrofoam can have long-term effects like cancer.

My Dog Ate Styrofoam: What Should I Do?

If you are affirmative that your dog has eaten Styrofoam, it is not a good sign and calls for attention. Follow the below instructions to prevent serious health issues.

1. Evaluate the condition

If they appear to be choking, unable to breathe, or gasping, immediately head towards the nearest veterinarian clinic and seek medical help.

Choking is also a risk factor for inducing vomiting and should be avoided. Any decision of inducement should be made by a veterinarian.

Refrain from any homemade treatment, and do not do anything you are unsure of. Always let the medical professional do their job. Home-made remedies have often worsened the conditions.
