can-dogs-eat-oatmealIt’s important to refrain from excess salt because dogs cannot tolerate a lot of this substance, and can even suffer from salt poisoning.

How Much Oatmeal Can Dogs Eat

Do not feed your dog a lot of oatmeal at once. Half a cup of cooked oatmeal is plenty for a small dog; bigger dogs can have a bit more.

The reason you should not give dogs a lot of oatmeal at once is that oatmeal is high in calories. As little as one cup of cooked oatmeal (234 grams) contains 158 calories. If you feed your dog a full bowl of oatmeal, she’ll get way more calories than she needs in a day, and will have no more room in her stomach for regular dog food. That would be bad because even though oatmeal contains nutrients that dogs need (e.g., potassium, vitamin A, vitamin B-6, calcium, iron, and magnesium), it doesn’t contain animal protein, and dogs need to have plenty of animal protein in their diets.

Is Oatmeal Good for Dogs?

Dogs can eat oatmeal, but would it be good for dogs to have some oatmeal in their diets?

Yes, as already mentioned above, oatmeal can provide your with many valuable nutrients that will help her to stay in good health.

#1: Oatmeal Can Be a Great Source of Magnesium for Your Doggy

As little as one cup of oatmeal contains up to 276 milligrams of magnesium. That alone is a good enough reason to include some oats in your dog’s diet, because magnesium is a very important nutrient for dogs and magnesium deficiency can lead to serious health problems in dogs.

Magnesium is needed for more than 300 enzymes in your dog’s body to function properly[2], it’s also an important nutrient for bone health and the production of protein.

By the way, oats are not only a great source of magnesium, but it’s actually one of the best sources of magnesium.

#2: Oatmeal Can Provide Your Dog with Iron

One cup of oatmeal contains more than 7 milligrams of iron, which is also an important nutrient for dogs.

Iron is essential for blood cells to be able to carry oxygen throughout the body and it is also important for the functioning of many enzymes[3].

#3: Oatmeal Would Provide Your Dog with the Much-Needed Dietary Fiber

Dietary fiber is a very important nutrient for your dog’s digestive system. The right amount of dietary fiber in your dog’s diet can help to prevent both constipation and diarrhea[4].

Too much dietary fiber, though, can actually cause diarrhea in dogs, so that is another reason why you shouldn’t feed your dog a large amount of oatmeal in a single sitting.

Besides keeping the digestive system running smoothly, dietary fiber may also help to reduce the chance of colon cancer in dogs[4].

#4: Oatmeal Is Also a Great Source of Potassium

As meat too is an excellent source of potassium, potassium deficiency is rarely a problem for dogs. However, if for some reason, you dog is not eating a lot of meat, then adding some oatmeal to your dog’s diet can also provide your dog with potassium.

Dogs’ bodies need potassium to keep a good fluid balance throughout the body and also for the proper functioning of nerves, muscles and many enzymes.

#5: Oatmeal Is One of the Best Plant Sources of Protein

When people talk about whether a particular dog food is good or not, then the food’s protein content seems to be the main indicator. That is so for a good reason, dogs do need quite a lot of protein in their diets to be healthy. Dogs bodies need protein for growth and development, but they can also use protein for energy.

Oats are a great source of protein, one cup contains around 26 grams of protein. And the protein from oats can definitely be useful for dogs, but don’t expect to fulfill your dog’s  protein need by oats alone.

All proteins are not the same. Proteins are made up of amino acids, and most plant sources of protein do not contain all of the amino acids that dogs need.

To fulfill your dog’s protein requirement with plant based protein sources, you have to combine different sources (e.g. legumes and whole grains) together. However, if there’s plenty of animal sources of food in your dog’s diet, then you don’t have to worry whether your dog gets all the amino acids she needs or not, because animal protein contains all the essential amino acids required by your dog’s body.

Unlike cats, dogs could, though, survive on plant based protein as well. And if for some reason your dog eats mainly plant based foods, then protein-rich grains like oats are definitely a good choice.

Oat Allergies in Dogs

Oats are a main ingredient in many commercial dog foods; that fact alone suggests that oat allergies are not common among dogs. However, if you notice anything strange in your dog’s looks or behavior after you have fed her oatmeal, consult with a veterinarian.
