[Alain Stevens – Petfood Advisor]

One of the first things many pet owners check on a kibble bag is the protein percentage. Higher protein numbers are often associated with better nutrition, especially for dogs and cats. Because of that, many pet food scoring systems heavily reward products that display impressive protein levels on the label.

But there is a major problem hidden behind this logic.

A protein percentage alone does not tell the full story.

Most scoring apps and online ranking charts mainly analyze declared analytical values. They can read “32% protein” on the packaging, but they usually cannot fully evaluate the biological quality of those proteins.

And that difference matters enormously in animal nutrition.

Two foods can display nearly identical protein percentages while delivering completely different nutritional value to the animal. One recipe may contain highly digestible animal-based proteins with an amino acid profile adapted to carnivores. Another may rely more heavily on cheaper protein sources that are less useful biologically, even if the final number on the bag looks impressive.

To a simplified scoring algorithm, both products may appear equally “high protein.” In reality, the nutritional outcome for the dog or cat may be very different.

Digestibility is another major blind spot.

A pet food may contain proteins that are difficult for the animal to absorb efficiently. If nutrients are poorly digested, the theoretical protein level on the label becomes far less meaningful in practice. Most simplified ABCDE-style scoring systems cannot truly measure how effectively nutrients are utilized inside the animal’s body.

Manufacturing processes also influence protein quality far more than many consumers realize. High-temperature extrusion, industrial processing, storage conditions, and ingredient oxidation can all affect the final nutritional value of the proteins. Yet barcode-scanning apps generally do not evaluate these technical factors.

There is also the issue of context.

A highly active working dog may benefit from a richer protein profile than a sterilized indoor cat with lower energy requirements. Senior animals, growing puppies, and pets with digestive sensitivities all have different nutritional needs. A generic score cannot fully adapt to those individual physiological situations.

Social media often oversimplifies the topic even further. Viral charts frequently rank foods almost entirely according to protein percentages, creating the impression that “more protein automatically means better food.” In reality, nutrition is much more nuanced than a single number.

Protein quality depends on several factors working together: ingredient origin, amino acid balance, digestibility, manufacturing quality, and adaptation to the animal itself.

This is why more consumers are beginning to question simplified pet food scores and looking instead for educational approaches that explain formulations in greater detail.

In pet nutrition, understanding where proteins come from and how they function biologically is often far more important than simply chasing the highest percentage printed on the package.
