Good Grains and Cereals
Wheat Dogs do not have to be grain-free; it is perfectly ok for them to have grains. In fact, grains like wheat and corn are great sources of protein, essential fatty acids, and fiber. If your dog has certain allergies, however, it might be best to avoid grains, but it truly depends on your dog. Ask your veterinarian for recommendations.
Bread can be eaten by dogs. Small amounts of plain bread (no spices and definitely no raisins) won’t hurt your dog, but it also won’t provide any health benefits either. It has no nutritional value and can really pack on the carbohydrates and calories, just like in people. Homemade bread is a better option than store-bought, as bread from the grocery store typically contains unnecessary preservatives, but it’s best to avoid it altogether.
Popcorn: Unsalted, unbuttered, air-popped popcorn is OK for your dog in moderation. It contains riboflavin and thiamine, both of which promote eye health and digestion, as well as small amounts of iron and protein. Be sure to pop the kernels all the way before giving them to your dog, as unpopped kernels could become a choking hazard.
Quinoa is OK for dogs. You can now find quinoa in some high-quality dry dog foods. The strong nutritional profile of quinoa makes it a healthy alternative to corn, wheat, and soy — starches that are often used to make kibble.
Cheerios can be a good training treat for dogs if the right variety is chosen. Plain Cheerios, Honey Nut, and Multi-grain are the flavors most recommended. They offer a nice crunch and just enough flavor to feel special. Other flavors should be used with caution and the frosted and chocolate flavors should be avoided. I would stay away from the cinnamon flavor since cinnamon can make dogs sick.
Other cereal: Corn Flakes, Honey Bunches of Oats, Grits, Rice Chex, Rice Krispies, and Special K. While dogs can eat cereal, it is not contributing to their nutrition. When you give cereal to a dog you are feeding them empty calories. I would stay away from the cinnamon flavors since cinnamon can make dogs sick if they get too much.
Raw Yeast Bread Dough should not be given to dogs or cats. Even after it is ingested, the yeast continues to convert the sugars to carbon dioxide gas and alcohol. Bloated, drunken pets are the result that can turn into a life-threatening emergency that requires hospitalization.
