Can Dogs Eat Cheerios? What the Label Says

Cheerios is the cereal that ends up on the floor around toddlers, which means dogs get a shot at it too.

What is on the label

I pulled the ingredient list for GENERAL MILLS, CHEERIOS, OAT CEREAL from USDA FoodData Central (branded foods) (product code 016000348516). Ingredients are listed from the most to the least by weight.

Whole grain oats, corn starch, sugar, salt, tripotassium phosphate, wheat starch. vitamin e (mixed tocopherols) added to preserve freshness. vitamins and minerals: calcium carbonate, iron and zinc (mineral nutrients), vitamin c (sodium ascorbate), a b vitamin (niacinamide), vitamin b6 (pyridoxine hydrochloride), vitamin a (palmitate), vitamin b1 (thiamin mononitrate), a b vitamin (folic acid), vitamin b12, vitamin d3.

Recipes change, and flavors and package sizes can differ, so read the bag you actually have before you rely on this list.

What matters for your dog

• Salt. ASPCA says excessive salt can cause increased thirst and urination and, depending on the amount, vomiting, diarrhea, tremors, seizures and even death. Size matters: the same snack is a bigger dose for a small dog.
• Sugar. Plain sugar isn’t poisonous to dogs, but it adds calories a dog doesn’t need. Sugar is the third ingredient on this label.
• Nothing else from ASPCA’s list. I compared this label to ASPCA’s list of people foods to avoid and didn’t find onion, garlic, chives, chocolate, caffeine, xylitol, grapes, raisins or macadamia nuts.

About Cheerios

The Original label lists whole grain oats, corn starch, sugar, salt, tripotassium phosphate and wheat starch, followed by added vitamins and minerals. There’s no onion, garlic, chocolate, dairy or xylitol.

Sugar and salt are both on the list, but sugar is third and salt is fourth, and this is a plain, low-flavor cereal. The main things to think about are that it isn’t food a dog needs and that a big bowl is a lot at once.

Honey Nut and other flavored Cheerios have different labels. I cover Honey Nut on its own page. Multi Grain and Frosted versions are different again.

Questions people ask

Can dogs eat Cheerios?

The Original label has nothing from ASPCA’s foods-to-avoid list. It’s not food a dog needs, so treat it as a rare nibble at most, and ask your vet if your dog has a special diet.

Is milk with the cereal a problem?

It can be. ASPCA says pets don’t have much lactase, so milk can cause diarrhea or digestive upset. Dry cereal is a different thing from a bowl with milk.

My dog ate a bowl of Cheerios. What now?

Watch for vomiting or diarrhea. If your dog is small, ate a lot, or has diabetes or another health problem, call your vet.
