How we would judge whether a high-protein food is actually high-protein
A percentage on the front of a bag is a claim, not a measurement. Here is how we trace it back to something you can verify.
Follow the number back to its source
Take the dry-matter protein figure, then read the first five ingredients. If the first animal ingredient is a named meat or meal and appears before the first legume or grain, the protein is mostly animal. If the list opens with pea protein, corn gluten meal or potato protein, the percentage is being propped up by plant concentrates that cost a fraction of meat.
Both foods can print 34% protein. Only one of them is feeding a dog the amino acid profile the number implies.
Match the protein level to the dog, not to the marketing
Growing puppies, working dogs and lean active adults generally do well on higher protein. A sedentary senior with a normal blood panel usually does not need more of it, and the extra calories that come with it are often the bigger issue.
For a dog with diagnosed kidney disease, protein is a clinical variable and the therapeutic diet is prescribed. Athletic marketing has no business in that conversation.
Protein without fat and calories is half the picture
High-protein kibbles are frequently high-fat as well, because fat is what makes them palatable and energy-dense. Read the kilocalories per kilogram alongside the protein number: two foods at 36% protein can differ by 15% in calories, which over a year is the difference between a lean dog and a heavy one.
We publish cost per 1,000 kcal on every product page for the same reason. It normalises price against energy, which is the only comparison that survives a change of bag size.
Mistakes we see most in this category
- Comparing the as-fed protein percentage of a wet food against a kibble
- Reading only the first ingredient and ignoring the four after it
- Assuming a 38% protein food is better than a 32% one without looking at what the protein is made of
- Feeding a high-protein, high-fat food to an inactive dog and wondering why the weight crept up
