Cereals are breakfast food made up of roasted grain, traditionally taken with milk. The grains include oatmeal, cornflakes, wheat, and rice. It contains fewer calories and is popularly consumed by many as a diet. In addition, it is a beautiful treat for those who love crunchy food. Thus, your dog will also enjoy munching on this crunchy snack. “Cereal” was derived from the word “ceres,” the Roman goddess of agriculture and harvesting.

Why Are Cereals Good for Dogs?

Cereals are less nutritional and cannot be your dog’s regular diet. However, cereals are far better than other dog treats and snacks with zero nutrition. Here is why cereals are suitable for dogs:

  • Cereals are loaded with fiber, enhancing healthy digestion and controlling constipation or diarrhea. It also helps in reducing the risk of colon cancer.
  • They give a sense of fullness to the appetite and thus will prevent obesity in dogs.
  • Cereals produce quality carbohydrates.
  • They also help in lowering the risk of heart disease.
  • Cereals provide relief for dogs with food allergies.
  • Cereals are rich in vitamins, protein, and minerals that help reduce stress.
  • Cereals also stabilize blood sugar levels.

Why Are Cereals Bad for Dogs?

Although cereals are healthy for dogs, overfeeding them can affect your pet. Cereals contain high carbohydrates, which leads to some health issues. These include:


Cereals contain carbohydrates and fats. So excessive consumption of cereals can make your dog gain weight.


Cereals contain sucrose and are rich in sugar. Hence when cereals are regularly fed, dogs are prone to diabetes.

Dental Issues

If dogs eat sugary treats, they develop tartar and plaque, and removing the sugar foodstuffs stuck between their teeth becomes difficult. It causes their teeth to decay.  

Urinary problems

Diets rich in whole grains or cereals can cause urinary tract infections and kidney failures due to urinary crystal formation.


A dog’s digestive system is more sensitive than a human’s. Thus, nuts like almonds cannot be digested by their stomach, which can cause indigestion.

Some ingredients in cereals that are bad for dogs


Xylitol, an artificial sweetener ingredient in sugar-free snacks, is used in some store-bought strawberry yogurt. It is hazardous for dogs, causing hypoglycemia and severe liver damage.
