Some proponents of corn will also tell you that it is the greed and lust of the expensive, high-quality dog food companies that make them advertise that corn is not good for dogs.

How to feed your dog fresh corn

Of course, this is all about processed corn in dog good. A few kernels of freshly boiled, unbuttered sweet corn is fine and a great occasional treat. It is not recommended at all that dogs eat corn as a primary substance in their food.

Dogs like corn, but a devoted owner should consider against giving their dog too much corn – for it can harm the dogs digestive system.

Many dogs love to chew on corn cobs – the taste of the salt, butter, and bits of corn, plus they are just fun to chew. Some dogs chew them up. Some dogs don’t. Corn cobs can cause intestinal obstruction, a very serious (and potentially fatal) medical condition. Additionally, some dogs are sensitive to corn and can suffer intestinal effects from that as well as the physical obstruction.

It is wise to keep all cobs away from your dog, safely secured in the trash. Dogs can be very “creative” when they want something in the trash, so make sure that the garbage is emptied or otherwise access protected from your pet.


If you suspect your dog has eaten a cob (or any food or foreign material that they shouldn’t have), please call your vet as soon as possible. The sooner you call the vet, the better it is for your pet.

Dogs should never eat the cob of a corn because they will not be able to digest it. It can clog their digestive tracts and kill them.

With which foods can dogs eat corn?

It is a good idea that you do not feed your dog corn that comes in the form of salsas or other mixtures. While it might be tempting to give your best friend a bite of a tortilla chip dipped in some kind of corn salsa, it is important to remember that salsas often contain garlic and onion, both of which can pose problems for your dog’s health.

In conclusion, corn is a controversial food for dogs not because of how it exist in its natural form, but how it is used in the production of food designed for dog consumption. We have friends that believe feeding dogs kibble that contains corn is tantamount to feeding a child candy bars for breakfast, lunch, and dinner. Conversely, we have heard veterinarians tell us that the harm corn posses is more hype than reality, and that so-called “boutique” brands often benefit from demonizing corn in their pitch to sell more product.

Let us know what you think, and let the debate rage on!

    “Dogs like corn, but a devoted owner should never give the dog to much corn – for it can harm the dogs digestive system.”

    Based on what? Your gut feelings? Harm the digestive system how? According to whom?

    You’re right to call this “bunkblog” because without any form of science backed basis, I say this is all bunk.

    • You are right, the language is biased. I will make some changes.’You’re right to call this “bunkblog” because without any form of science backed basis, I say this is all bunk.’ I have to admit that’s pretty funny, but “BunkBlog” comes from the name of our pug, Bunk, who is name after Detective Bunk Moreland, from the television show, The Wire. I suggest you watch.

      My pug had intestinal issues and always had the sound of fluid on his lungs. 4 days after I switched him from corn and his bowel movements are regular and I the congestion on his lungs is gone… What was the primary ingredient in his previous food??? Corn… New food no corn… It was corn.

  3. Zipper the pekapom on

    Corn gives me bad gas. And I mean bad! My mom has to move away from me when I pass corn gas, and I don’t like being away from her. I eat lamb and rice dog food, and though I love corn on the cob, I know I shouldn’t have it.

  4. I wonder if corn is inherently indigestible or if it is the gmo corn that is really so bad. so many people are turning to a gluten free (corn and wheat free) diet and doing really well…but what pet foods out there are corn and wheat free?

  5. Mine ate 4 cobs today and he’s perfectly normal,but i wanted to see if its okay.Thank’s for the info 😀

  6. my dog, a yorkie/chihuahua eats royal canin, and gasp omg! iams and purina that i buy at the grocery store.
    she is doing just fine. in fact the purina one smartblend is the only dry food she will eat without me having to add can food to it – i think a lot of dog owners have been brain washed into thinking that grain free is the way to go. grain free is definitely the way to go if your dog has allergies to grains.
