Can Dogs Eat Corn Cobs? Why It’s Dangerous

corn cobs for dogs

It may seem like a nice treat to let your dog gnaw on a corn cob, but let’s be real: can dogs eat corn cobs? The answer is no; giving your dog corn is not something you should do.

Corn cobs and corn kernels can be very dangerous for dogs. Especially if you give your dog an entire corn cob. While they’re not toxic, they can be a choking hazard or worse … so if your dog ate corn cob you need to know about the risks.

Corn cobs are indigestible. They don’t break down in your dog’s stomach … and that means there’s a high risk of bowel obstruction. And that can lead to dehydration, pain and even death

So … here’s information about …

  • Bowel obstructions
  • How to recognize them
  • What to do if your dog ate corn cob
  • The safe way to share corn with your dog

What To Do If Your Dog Ate A Corn Cob

If your dog has eaten a cob of corn, contact your vet immediately. Depending on the situation, she may want to see your dog immediately. Or she may tell you to watch for signs of an obstruction … otherwise known as intestinal blockage.

Symptoms will vary depending on whether it’s a partial or complete blockage. Your dog will show more obvious and severe gastrointestinal distress symptoms with a complete blockage.

If your dog shows any of these symptoms after he eats a corn cob, he may have an obstruction …

  • Dehydration (sticky gums)
  • Diarrhea
  • Constipation
  • Lethargy (tired, inactive, less responsive)
  • Abdominal pain (doesn’t want stomach touched)
  • Vomiting
  • Bloated or swollen stomach
  • Loss of appetite

Small partial obstructions may pass on their own without damage. But large or complete obstructions could require surgery. If your dog’s symptoms are severe (or they’re slowly worsening) … get to the vet immediately. In severe cases, intestinal blockages can be life threatening.

Should I Induce Vomiting iI My Dog Ate A Corn Cob?
No, don’t induce vomiting unless your vet recommends it. It’ll depend on the size of your dog, the size of the corn cob, and how long it’s been since he ate it. Call your vet and tell her everything you know .. including any symptoms your dog has.

Prevention: Practice Garbage Safety

There are three main reasons your dog could end up with a corn cob …

  1. You give it to him (and now you know why you shouldn’t)
  2. You leave them out as a treat for the birds or squirrels
  3. Your dog finds it in the trash

To make sure you dog doesn’t snatch a corn cob by accident … you need to dispose of it safely.

Your safest bet is to throw the cobs straight into a garbage can with a secure lid. If you have a dog who has a habit of getting into the trash no matter how well sealed it is … you may want to take some extra precautions.

Here are some options …

  • Put the corn cobs in a bag in your garage or dumpster.
  • Use a trash can with a locking lid.
  • Store your kitchen garbage under the sink or in a closet.
  • Put a child safety lock on the door.
  • Empty your garbage more often to prevent the smells that attract your dog.    
  • Put a weight (like a brick) in the bottom of the trash can so that it isn’t easy to knock over.

How To Share Corn With Your Dog

Corn can be a tasty treat for your dog and does offer some nutritional value. Corn is a source of …

  • Protein
  • Linoleic acid
  • Antioxidants
  • Fiber
  • Vitamins
  • Fatty acids

But now you know you shouldn’t leave your dog unsupervised with corn on the cob. And while it may seem safe so long as you hold the cob for your dog to clean off the remaining corn … dogs can be fast. It doesn’t take much time for a medium or large dog to grab hold of the cob and swallow it whole.

If you want to share corn with your dog, cut it off the cob and give it to him as a treat or add it to his food.

You also want to try and buy organic corn. Corn is one of the many crops that are genetically modified. In fact, 88% of US corn crops are genetically modified.

And there are many health risks linked with GMO crops due to the amount of the herbicide glyphosate (Roundup) that’s often used on them.

  • Altered gut bacteria
  • Damaged kidney cells
  • Leaky gut syndrome
  • Organ damage
  • Cognitive issues
  • Increased rates of cancer
  • Food allergies

And those are only some of the problems ….

To avoid the risk of GMO corn, make sure you only share organic corn with your dog.
