These days, we want to be more informed about ingredients in pet foods. There is a lot of misinformation out there about protein sources, grains, by-products and raw food diets. These are some of the common myths about pet food:

1. By-products are bad
2. Grain-free diets are better. To learn more about this topic, read our article on What to Know About Grain-Free Dog Food
3. Corn is bad
4. Raw meat diets are healthier
5. Natural or Holistic Diets Are Better

Purchasing your pet food from a reputable manufacturer will help avoid health problems in your pet due to poor quality ingredients or improper formulation. Reputable pet food manufacturers are very selective about their sources and employ full time qualified nutritionists. They perform scientific testing and strict quality control to ensure that each ingredient and the finished pet food meets exact nutrient specifications.

Always remember that the ingredient list and the nutritional analysis printed on the label do not provide an accurate picture of that diet.

Fancy marketing which caters to fads such as “grain-free” and “holistic, all-natural” may lure many pet owners into believing the company with the best marketing tactics. Being armed with the right knowledge about pet food facts and myths will help prepare you for making the best choice for your pet.

Myths About Pet Foods in 2025

What makes some protein sources better than others?

Different protein sources in pet food vary widely in their amino acid profiles and digestibility, which are crucial for your pet’s health. Highly digestible proteins, such as those from animal meats, provide more usable amino acids per gram than lesser digestible plant-based proteins. The biological value of a protein also matters; it reflects how readily a given protein can supply the amino acids necessary for growth and maintenance. Therefore, selecting high-quality protein sources, as verified by reputable manufacturers who conduct rigorous quality control, ensures optimal nutritional benefits for pets.

What is the relationship between protein levels and kidney health?

High protein levels in pet diets are often believed to damage kidney function; however, this is a misconception, especially in healthy animals. Protein requirements vary among pets, but normal kidney function can process high protein diets efficiently. It’s critical for pets with pre-existing kidney conditions, as they often require protein adjustments to reduce kidney workload. Thus, while protein is vital for pet health, its impact on kidney health is generally overstated except in cases where the kidney is already compromised. Always consult with a veterinarian to tailor dietary needs to specific health conditions.

What is the truth about meat vs. meat meal?

Meat in pet food refers to the muscle flesh from animals, whereas meat meal consists of ground and rendered clean flesh, skin, and sometimes bone, with moisture removed. Meat meal contains a more concentrated protein source compared to whole meat, which can be beneficial in pet diets. However, the quality of protein varies, so the source and processing methods are critical. Whole meat provides higher moisture content and fewer processed ingredients, which some pet owners prefer for maintaining their pets’ health. Both forms can be nutritious when sourced and processed responsibly.

Are raw eggs beneficial for coat health?

Raw eggs are not recommended for improving coat health in pets. While eggs contain beneficial nutrients such as proteins and fatty acids, raw eggs also present risks. The avidin in raw egg whites can inhibit the absorption of biotin, a nutrient crucial for healthy skin and coat. Additionally, raw eggs may carry salmonella, posing health risks to both pets and their owners. It’s advisable to consult with a veterinarian for safer, more effective options tailored to individual pet health needs for maintaining a healthy coat.

What is the connection between grain-free diets and heart health?

Grain-free diets for pets, particularly dogs, have been linked to a condition known as canine dilated cardiomyopathy (DCM). This condition leads to an enlarged heart that doesn’t function properly. Research suggests that certain grain-free foods may lack taurine, an amino acid important for heart health, or may contain ingredients that interfere with its metabolism. While not all pets on grain-free diets will develop heart issues, there is a notable correlation that warrants careful consideration and dietary choices based on comprehensive nutritional needs rather than marketing trends.
