If you are looking to provide your pet with the highest quality diet to ensure his health and the longest life possible, it is vital to inform yourself about the ingredients included in many dog food products. GMO ingredients have existed in both human and pet foods for several decades, but their effects have only recently come to light.

As a pet parent, your responsibilities include reviewing ingredients thoroughly and not settling for the marketing catchphrases that sell you a “wholesome” or “natural” product. Many dog food brands market their product based on specific ingredients and fail to represent the genetically engineered ingredients infused into their recipes.

If you are wondering if you are supplying your adored fur buddy with the most optimal diet, keep reading to keep yourself apprised of the many dietary dangers being sold to you for your pup’s consumption.

What are GMOs?

GMO stands for genetically modified organisms; these are also commonly referred to as genetically engineered organisms. Dr. Rick Meilan, a molecular tree physiologist at Purdue University, explains that genes are comprised of DNA and they put together a list of directives for how cells are supposed to behave.

The word “modified” refers to a shift in the biological structure of a living organism. The last word is “organism,” acknowledging there has been a forced change to the molecular structure of living things, like crops.

To put it simply, genetically modified means DNA is being extracted from one organism and being forcefully injected into a different organism, creating an artificial crop. There are several crops included in dog food, such as soy, corn, potatoes, tomatoes, and peas.

GMOs seem inescapable when looked at through a simple lens but the truth is, they can be avoided. There is plenty of controversy surrounding the studies deeming GMOs safe, particularly because those studies are conducted by entities that profit from the use of GMOs, creating a conflict of interest.

With a keen eye on labels, you can find a non-GMO dog food that will keep your animal companion from suffering the health problems generally associated with the consumption of these unnatural ingredients.

List of Common Genetically Modified Crops

  • Corn – Corn is a very common crop that is used to create several different ingredients used in processed dog food. The genetic modification includes chemicals that prohibit herbicides from damaging corn while out in the field, and only targeting weeds. Since the chemical protects the corn, excessive amounts of the herbicides can be used. Following testing of lab rats, there was a higher occurrence of kidney and liver problems following consumption of the modified corn (Sherbo, 2024).
  • Potatoes – Potatoes have been genetically modified to avoid dark marks on the skin, giving them a more appealing appearance. They have also been engineered to expel a built-in pesticide whenever an insect attempts to feast on it, repelling further attempts to attack the crop (Scott, 2024). Studies conducted have shown that lab rats develop immune system issues, have disruptions to their stomach lining, and receive damage to vital organs following the consumption of modified potatoes (Scott, 2024).
  • Alfalfa – Alfalfa is another crop that was genetically modified to make it resistant to herbicides, resulting in similar effects as corn. The disproportionate amounts of herbicide used on this crop make it an unsafe choice for your dog’s consumption, based on lab testing completed with rats.
  • Tomatoes – The genetic modification of tomatoes has long been an issue, with the first variation never making it out for public consumption. Calgene, the creator-in-chief of a series of genetically engineered tomatoes, conducted a 28-day feeding study on several lab rats. The results were unfortunate for several of the rats who consumed the modified crop and experienced ruptures in their stomach lining followed by internal bleeding (Smith, 2010).
  • Soy – Soybeans are a very common American crop that is distributed in part for human consumption and in part as an additive for dog food, usually as soybean meal. While this additive can be considered high in protein, its genetic modification affects its absorption. Many of our beloved furballs are allergic to this ingredient and you may have already witnessed those reactions which include tummy upset, diarrhea, vomiting, or other signs of discomfort.
  • Beets – Beet pulp is an ingredient often used in dog food. This is generally considered a red-flag component because it is highly processed; however, you will notice many proponents of this food additive who claim the ingredient is a good source of fiber that aids with muscle growth. If genetically engineered, it is just another untrustworthy additive with strong coloring that will not aide your dog’s diet and more than likely will hinder his health.
  • Peas – Peas are yet another crop tainted by genetic modification. While peas can provide important nutritional components for a dog’s health, if they are genetically engineered, their health benefits may be outweighed by their risks. Pea flour, for instance, is an ingredient that dogs may have a difficult time digesting, due to its structure.

GMO Health Risk and Issues

GMOs, by nature of their artificially altered structures, produce health risks for pets that include bleeding stomachs from injured stomach linings to affected immune systems that are unable to fight off foreign viruses (Scott, 2024).

There was a study conducted by Cornucopia Institute Research that determined genetically modified soy products that were fed to female lab rats resulted in the death of their babies within a three-week period.

Male rats were also part of the study and upon being fed with genetically modified soy, their outward reproductive organs turned dark blue from a natural pink color. There were multiple DNA changes noted within the study, whether they were fed modified soy or corn (Scott, 2024).

There is a common virus that is part of the genetic modification process called CaMV (Scott, 2024), it is used in canola which is a common ingredient in dog food and is known to cause viral illnesses

If you are considering a dog food product that contains dairy, you may want to review studies on the effects of genetically modified milk products which, according to Dana Scott from Dogs Naturally Magazine, has the potential of leading to thyroid cysts and internal organ damage, according to lab rat testing.

Many of our furry best friends suffer from allergic reactions to food additives, particularly breeds with a history of digestive difficulties. When your dog’s health is revered, as a pet parent, these facts are important to consider for ensuring their happy, long lives alongside our families.
