Can Dogs Eat Oatmeal?

Yes, dogs can eat oatmeal. Cooked oatmeal is an excellent source of fiber and carbohydrates for energy.


Your dog can safely eat most forms of oatmeal, but avoid those packets of flavored oatmeal, as they may contain other ingredients that are harmful to your dog, including the deadly sweetener xylitol. Stick with plain oats.

You have likely seen dog foods and treats that include oatmeal as an ingredient. That’s because it is nutritious. Beneficial nutrients in oatmeal for dogs include:

  • Fiber
  • Vitamin B
  • Omega-6 fatty acids
  • Magnesium
  • Zinc
  • Antioxidants

These qualities can help to support heart and gastro-intestinal tract health for your dog. Oatmeal also can help promote healthy weight and stable blood glucose levels. Oatmeal is good for dogs with diarrhea or loose stools because it’s high in fiber.

How to Feed Oatmeal to Dogs

When cooking oatmeal for your dog, use water instead of milk. Most dogs are lactose intolerant, so water is the better choice. Follow the instructions for the plain oats of your choice. You can even use overnight oats that soak overnight.

As with any new food, introduce oatmeal gradually so that your dog doesn’t get an upset stomach. Start with about a spoonful of cooked oatmeal at a time. You can work up to about 6 ounces of oatmeal a day per 25 pounds of the dog’s bodyweight.

If you plan to home-cook your dog’s meals rather than just feeding oatmeal as a supplemental snack, consult with a veterinary nutritionist or use to formulate a complete and balanced diet. This will ensure that your dog gets all the nutrients that she needs to be happy and healthy long term.

And don’t forget to let the oatmeal cool before you serve it to your dog!

Oatmeal in Dog Food

Oatmeal is sometimes used in commercial dog foods as an alternate carbohydrate source instead of wheat, rice, or corn. Provided that the dog food packaging has an AAFCO statement declaring that it is formulated to meet nutritional standards for your dog’s life stage, you are all set to feed it to your dog as-is.

Oatmeal is also used in many treats that your dog may enjoy.

Can Dogs Eat Uncooked Oatmeal?

Dogs should not eat uncooked “raw” oatmeal. The cooking process makes it easier for dogs to digest. Eating dry uncooked oatmeal in large quantities may cause your dog to bloat, which is a medical emergency.

Can Dogs Eat Oatmeal Cookies?

Dogs can eat oatmeal cookies once in a great while depending on what else is in them. Remember that raisins and chocolate chips are both toxic to dogs, which rules out many oatmeal cookies. The high sugar content of many cookies is not ideal for our canine companions, however.

Unless you are certain all the ingredients in an oatmeal cookie are safe for dogs, keep that treat for yourself.
