In recent years, multiple pet food safety incidents have raised concerns. As responsible dog owners, we must keep our eyes open when purchasing feed and carefully avoid harmful ingredients. The following reveals six veterinarian-certified additives that should not appear in dog food, helping you easily identify them and ensuring the health of your furry friends.
The Danger of Melamine in Pet Food
When it comes to the safety of our beloved pets, vigilance is key. One substance that should raise immediate concern is melamine.
What is Melamine?
Melamine is an industrial chemical with no place in the food chain. Yet, in the past, some unethical manufacturers have intentionally added it to pet food, falsely labeling it as "gluten." This fraudulent practice has had devastating consequences.
The 2007 Pet Food Recall
In 2007, a widespread recall of many brands of cat and dog foods occurred due to contamination with melamine and cyanuric acid. The recalls in North America, Europe, and South Africa came in response to reports of kidney failure in pets. Veterinary organizations reported more than 100 pet deaths among nearly 500 cases of kidney failure by the end of March. However, many sources speculate that the actual number of affected pets may never be known, and experts think that the actual death toll could potentially reach into the thousands.
The Deadly Combination
Melamine alone poses a risk, but it becomes an even greater threat when combined with cyanuric acid. This combination can form crystals in the kidneys, leading to kidney failure and death, as seen in the tragic cases of pets who consumed contaminated food. After eating the adulterated food, dogs' and cats' bodies became chemistry labs where melamine reacted with cyanuric acid to form durable crystals that clogged pets' kidneys. By April 2007, those crystals had caused kidney failure in 236 cats and 112 dogs, according to a survey of veterinarians. Consumer reports to the US Food and Drug Administration (FDA) suggest that approximately 1,950 cats and 2,200 dogs died.
Symptoms of Melamine Poisoning
Pet owners were advised to monitor their animals for the following signs of possible kidney failure that may be associated with the unknown toxicant: loss of appetite, lethargy, depression, vomiting, diarrhea, sudden changes in water consumption, and changes in the frequency or amount of urination. It was advised that pets exhibiting these symptoms should be taken for veterinary care as soon as possible, even if the animal did not eat any of the recalled pet food, as these signs may be indicative of other illnesses.
The Role of Melamine and Cyanuric Acid
Research has focused on the role of melamine and related compounds in causing kidney failure. Researchers reportedly had ruled out aminopterin contamination and had found a "spoke-like crystal" in contaminated wheat gluten and rice protein concentrate and the tissues and urine of affected animals. The crystal has been said to serve as a biomarker for contamination and is approximately 30% melamine.
What Can You Do?
- Read Labels Carefully: Be aware of the ingredients in your pet's food and research any unfamiliar substances.
- Choose Reputable Brands: Opt for pet food brands with a strong reputation for safety and quality control.
- Stay Informed: Keep up-to-date on pet food recalls and safety alerts
The Risks of BHA, BHT, and Ethoxyquin in Pet Food
BHA (Butylated Hydroxyanisole), BHT (Butylated Hydroxytoluene), and Ethoxyquin are artificial preservatives commonly found in pet foods. While the U.S. Food and Drug Administration (FDA) permits their use in small amounts, concerns have been raised regarding their potential health risks.
Studies suggest that these preservatives may have carcinogenic properties and can cause skin and eye irritation in dogs. Ethoxyquin, in particular, is also used as a pesticide and herbicide, raising further questions about its safety.
What are BHA, BHT, and Ethoxyquin?
BHA and BHT are artificial preservatives added to oils to slow down deterioration. Ethoxyquin is a chemical preservative regulated as a pesticide by the FDA.
Potential Health Impacts
- Carcinogenic Potential: BHA and BHT have been classified as potential human carcinogens.
- Irritation: These preservatives can cause skin and eye irritation in pets.
- Organ Damage: Ethoxyquin has been linked to liver and kidney damage in animals.
FDA Regulations and Concerns
The FDA allows trace amounts of ethoxyquin residue in human foods but permits higher amounts in pet food and livestock feeds. There is ongoing debate and research regarding the safety and regulation of these additives.
Alternatives
Some pet food manufacturers use natural preservatives like mixed tocopherols (Vitamin E) to ensure freshness without the potential risks associated with synthetic preservatives.
It is advisable to check pet food labels and consult with a veterinarian regarding the best dietary choices for your pet.
Propylene Glycol in Dog Food: Should You Be Concerned?
Propylene glycol: Propylene glycol is often used to maintain food texture and moisture in various products, including dog food. It acts as a humectant, which means it helps retain moisture, keeping the food soft and appealing. You can find it in soft treats and semi-moist dog foods.
What is Propylene Glycol?
Propylene glycol is a synthetic chemical. It gained attention when it was used as a safer alternative to ethylene glycol in antifreeze. While propylene glycol is considered less toxic than ethylene glycol, concerns about its safety in pet food persist. It can also be found in items like laundry detergents and soaps.
Is Propylene Glycol Safe for Dogs?
The FDA and the veterinary community generally believe that small doses of propylene glycol do not adversely affect dogs. The accepted level of propylene glycol ingestion is up to 8% of the total diet for dogs. A two-year controlled study showed that dogs tolerated levels up to approximately 8% without adverse effects. However, continuous exposure to this synthetic substance is a concern for some pet owners.
It's worth noting that the FDA banned the use of propylene glycol in cat foods because studies showed that it could cause Heinz body anemia, a serious blood disease, in cats.
Potential Risks and Side Effects
Even though propylene glycol is considered "Generally Recognized as Safe" (GRAS) by the FDA, some anecdotal evidence raises concerns. Potential side effects of propylene glycol poisoning include central nervous system effects, kidney damage, depression, lactic acidosis, incoordination, seizures, severe sedation, and lethargy.
The Bottom Line
Given the choice, why not opt for dog food that doesn't contain propylene glycol? Many pet owners prefer to avoid non-nutritive additives in their dog's food.
What to Look For
Propylene glycol may be listed as propane-1,2-diol or E1520 on ingredient lists. Always check the ingredient lists on your pet's food, treats, and supplements.
Understanding Meat Powder in Dog Food
Meat powder, often found in dog food, may appear to be a source of protein; however, its true origins can be concerning. It may consist of by-products from slaughterhouses, including scraps, bones, and internal organs. In some cases, it could even include the remains of deceased or sick animals.
Regulatory Variations
The standards for regulating meat powder vary significantly across different countries. This inconsistency can lead to alarming discoveries, such as the presence of DNA from endangered species like sharks and sea turtles in some pet foods.
Implications for Pet Owners
As a pet owner, it is crucial to be aware of the ingredients in your pet's food. Understanding what constitutes meat powder can help you make informed decisions about your dog's diet and overall health.
While meat powder can provide protein, the potential sources raise ethical and health concerns. Pet owners should seek transparency from manufacturers regarding their sourcing practices to ensure they are providing safe and nutritious food for their pets.
MSG in Dog Food: A Hidden Danger
Monosodium glutamate (MSG) is frequently added to dog food to enhance its flavor. However, MSG offers no nutritional benefits and may pose significant health risks to your beloved pet.
The Risks of MSG
While MSG might make dog food more appealing, it can lead to several health issues:
- Obesity: MSG can stimulate excessive eating, potentially leading to obesity and related complications.
- Metabolic Disorders: Regular consumption of MSG may disrupt your dog's metabolism.
- Neurotoxicity: Some studies suggest that MSG can have neurotoxic effects, potentially damaging the brain and nervous system.
Symptoms of MSG Poisoning in Dogs

Artificial Colors in Dog Food: A Cause for Concern?
Have you ever wondered why your dog's kibble comes in a variety of vibrant colors? The truth is, dogs don't care about the color of their food; these artificial colors are purely added to cater to human vision.
While colorful food might be appealing to us, it's important to consider the potential risks associated with artificial food colorings in pet food. Some food colorings (such as Red No. 3 and Red No. 40) have been studied and linked to cancer or allergic reactions, and are even banned in some countries.
Potential Risks of Artificial Food Colors
- Hyperactivity: Some artificial food colorings, like Yellow 5, have been linked to hyperactivity, aggression, and insomnia in dogs.
- Allergic Reactions: Certain dyes may trigger allergic reactions in sensitive animals.
- Cancer Concerns: Red 40 has been found to be tainted with cancer-causing contaminants. Blue 2 has been linked to brain tumors.
The FDA's Stance
Despite concerns, the FDA maintains that many food dyes are generally safe and has no plans to ban their use in pet foods. However, it's worth noting that the FDA has banned over 25 food color additives since the 1960s, and the remaining approved dyes are subject to strict regulations.
Natural Alternatives
If you're concerned about artificial food colorings, consider opting for dog foods that use natural dyes or no dyes at all. Natural dyes are derived from organic sources like vegetables, spices, or algae.
The Bottom Line
Ultimately, the decision of whether or not to feed your dog food containing artificial colors is a personal one. It is important to advocate for your pet and make educated decisions for their health. Weigh the potential risks and benefits, and consult with your veterinarian if you have any concerns.
