More than Just a Scrap: The Dangers of Foreign Body Ingestion

Summer BBQs are a highlight of the season, but they also bring hidden hazards for our four-legged friends. While we often worry about toxic foods like grapes and onions, one of the most common and most dangerous emergencies we see at Mission is foreign body ingestion.

From chewing toys and socks to the classic summer culprit, the corn cob, dogs and cats have a knack for swallowing things they shouldn't. Unlike food, these items don’t break down, which can lead to serious internal complications.

While some small, smooth objects might pass, many others, especially corn cobs, are the perfect size and texture to get stuck.

Why “Foreign Bodies” Are So Dangerous

A “foreign body” is any non-food object that finds its way into your dog’s digestive tract. While some small, smooth objects might pass, many others, especially corn cobs, are the perfect size and texture to get stuck.

• Intestinal blockages: complete or partial obstructions that prevent digestion

• Tears and perforations: rough edges can scrape or puncture the lining of the digestive tract

• Infection & dehydration: blockages can lead to severe illness and tissue death in the intestines

Act Quickly. Don’t “Wait and See”

If you know or suspect your dog has swallowed a foreign object, time is of the essence.

• Call your veterinarian or an emergency clinic: They’ll guide you based on your dog’s size and how long it’s been.

• Don’t induce vomiting unless a vet tells you to: Cobs can get stuck on the way back up.

• Watch for other warning signs: if the object has already moved into the intestines, you may see:

  • Vomiting or dry heaving

  • Loss of appetite

  • Lethargy or weakness

  • Abdominal pain, which can look like a hunched bank or whining

  • Straining to poop or diarrhea

Diagnosis and Recovery

Most foreign body cases require imaging, such as X-rays or ultrasound, to locate the object. While some ingestions may pass through the system with your veterinarian's help, many require surgery to safely remove the blockage.

At Mission Animal Hospital, we see foreign body emergencies nearly daily. These cases can escalate from “a little lethargic” to life-threatening very quickly.

How to Prevent a Digestive Emergency

If you know or suspect your dog has swallowed a foreign object, time is of the essence.

• Secure the scraps: Clear plates and trash quickly. Corn cobs, peach pits, and avocado pits are all tasty treats that can easily become an emergency.

• Know your chewer or string chaser: If your dog destroys toys, or your cat always goes after strings or ribbon, stick to toys that are indestructible and safe.

• Dog-proof the trash: Use heavy, locking lids on indoor and outdoor bins.

• Educate guests: Remind friends and family not to toss scraps to your pet, no matter how much they beg.

If your pet ate a non-food item, don’t wait for symptoms to appear. Call your veterinarian immediately. Quick action is the best way to prevent complications and save your pet’s life.
