My dog needs to be on a lymphoma-inhibiting, high-protein, low-carb diet. I use a nutritional tracker for him to make sure he is getting the proper amounts of protein, fat, and carbs. When doing the calculations to determine the grams of Protein from the percentage on the dog food label, I'm using the formula: g P = (% P * kcal) / 4 But when determining the nutritional content of canned dog food, do I use the Guaranteed Analysis percentages or the Dry Matter percentages in the formula above? For example: Using a Merrick 5 Star Entree can label: Protein 9%, Fat: 4%, Fiber: 1%, Moisture: 81% with 380 kcal/can. The Dry Matter Percentages work out to be as follows: P: 47%, F: 21%, Fb: 5.3%, Ash: 8%, Carbs: 24% So, when calculating grams from percentage, do I use the 9% Protein or the 47% Protein in the formula? Using the entire contents, it works out to be 8.5 grams of Protein per can, while using the dry matter, it works out to be 45 grams of Protein per can. The 8g seems too low and the 45g seems too high for one can, so I really have no idea which is right. I would appreciate it very much if you can answer this question.

No, it's not. Nutrient analysis may only be figured meaningfully on dry matter basis... one food can only be compared to another after all of the water is removed... i.e. you cannot compare the protein of kibble (10% moisture) to the protein in chicken (75% moisture) without removing the water from each. All that can be in a carcass is water, protein, fat, minerals and vitamins. A chicken, for example, is roughly 75% water. When that is removed, what is left is roughly 65% protein and 22% fat.
