Can dogs eat rice?

Rice is a cereal grain that is a staple food for a significant portion of the world's population. It is the seed of the grass species Oryza sativa (Asian rice) or Oryza glaberrima (African rice). There are various types of rice, including white rice, brown rice, basmati rice, jasmine rice, and others, each with its own characteristics and uses.

The rice plant produces seeds encased in protective outer layers. The process of milling removes these outer layers to produce edible rice grains. White rice is milled further to remove the bran and germ, while brown rice retains these nutritious layers.

Rice sits alongside other grains such as wheat, oats, corn, barley, and rye.

Serving as a dietary staple for billions across diverse cultures, rice is valued for its affordability and widespread availability. However, it lacks significant amounts of vitamins, minerals, and phytonutrients. Its primary benefit lies in providing carbohydrates for energy once being cooked or milled into flour before consumption.

Is Rice Good for Dogs?

Rice is primarily a carbohydrate, lacking in many other essential nutrients. While dogs don't necessarily require carbohydrates, if you choose to include them in their diet, there are more nutritious sources than rice.

Comparing brown and white rice, brown rice offers more nutrients such as fibre, manganese, small amounts of iron, and B vitamins like niacin. However, the milling process that turns brown rice into white rice removes the outer bran and germ, reducing its fibre, iron, and niacin content. White rice is then enriched with additional nutrients, including niacin, iron, and B vitamins like folic acid, to compensate for what was lost.

Although brown rice may have higher levels of antioxidants and essential amino acids compared to white rice, other foods like green leafy vegetables, meat, poultry, eggs, and fish offer similar benefits with fewer calories. These foods also provide dogs with necessary energy.

Can Dogs Digest Rice?

Yes, dogs can digest rice and other carbohydrates. Unlike humans who produce the digestive enzyme amylase in their mouths, dogs get amylase from their pancreas. 

If we look at how a dog's body (and a human's) processes carbohydrates, there are 8 hormones to raise blood sugar in times of scarcity but only one to lower it - insulin. This is because in the past, there wasn't much excess food, and there was minimal need to deal with rare spikes in blood sugar by storing it as fat.

In contrast, in today's industrial age with modern food processing and the diet of domestic dogs, they often consume a processed diet high in carbohydrates. This can lead to the body storing excess as fat, contributing to many dogs becoming overweight and experiencing digestive problems.

Can Dogs Eat Uncooked (Raw) Rice?

No. In the natural habitat, herbivores like deer gravitate towards leaves, roots, or berries for sustenance. On the other hand, carnivores such as dogs or wolves extract raw meat from their prey carcasses. They might consume partially digested contents from the stomach, like fruits, vegetables, or leaves during the process of fermentation.

Raw grains such as wheat, corn, barley, and rice from paddies hold little appeal to animals in their natural state. It's only when these grains undergo processes like milling, soaking, sprouting, cooking, or baking that they become more palatable and digestible.

When left in their raw form, grains pass through the digestive system intact, featuring a robust outer shell for protection. Unfortunately, anything within that shield remains indigestible and unabsorbable, appearing in the stool unchanged from its initial state.

Furthermore, there's an additional concern with rice: it is highly likely to contain arsenic.

Is Rice Safe for Dogs?

No it’s not and that’s because it’s common to find arsenic in rice. Arsenic is a naturally occurring element that is present in soil, water, and some crops, including rice. Rice tends to absorb more arsenic from the environment compared to many other grains.

Arsenic is found in two forms: inorganic and organic. Inorganic arsenic is considered more toxic, and it is the type of arsenic that is more commonly found in rice. The levels of arsenic in rice can vary depending on factors such as the type of rice, where it is grown, and environmental conditions.

While arsenic is generally present in low levels and might not pose an immediate threat to most dogs, long-term exposure to high levels of arsenic has been associated with health concerns, including an increased risk of certain cancers and other health issues.

Here are some risks that eating arsenic can cause:

  • Cancer
  • Vascular disease by narrowing or blocking blood vessels
  • High blood pressure
  • Heart disease
  • Diabetes
  • Neurotoxicity and diminished brain function
  • Arsenic can also be passed from bitch to puppy, leading to birth defects and irregular development.

Too much arsenic is harmful, and while small amounts in food are usually considered safe, eating it regularly for a long time can lead to issues. Since many dog foods have rice, and dogs eat them daily throughout their lives, it can become a problem.

Why Is There Rice in Dog Food?

Rice is often used as a cost-effective filler in processed dog food, but this practice comes with several drawbacks:

Nutrient Deficiency: Rice lacks key nutrients, prompting the addition of synthetic vitamins, minerals, and amino acids, which may not be effectively recognized by your dog's body.

Mycotoxins: Rice can harbour mycotoxins, byproducts of mould and fungus, posing potential health risks.

Aflatoxins (AFB1): AFB1, a well-known mycotoxin found in rice, is recognized by the FDA as "the most potent known natural carcinogen."

Incomplete Protein Source: Rice does not provide a complete source of protein, necessitating the addition of amino acids to compensate.

Genetic Modification (GMO): Most rice used in dog food is genetically modified (GMO), and GMOs may negatively impact the beneficial bacteria in your dog's gut.

Pesticide Exposure: Crops like rice, used in dog food production, are often sprayed with pesticides.

Overreliance on Starches: Starchy ingredients like rice can dominate the composition of dog food, reducing the inclusion of more nutritious and expensive components such as meat, poultry, fish, and eggs.

Should Dogs Eat Rice?

No, just because dogs can digest rice doesn't mean it's the best choice. There are healthier options for vitamins, minerals, and energy, such as animal proteins, good fats, fruits, and vegetables. These choices are less likely to make your dog gain weight or be poorly from issues like arsenic or low taurine levels.
