Raw feeding guidelines are based on a percentage of body weight, not calorie counting. The standard starting point for a healthy adult dog is 2-2.5% of their ideal body weight per day. The percentage varies by life stage because activity level, metabolism, and growth rate differ significantly between a 10-week-old puppy and a 10-year-old senior dog.
Most raw feeders follow one of two models. BARF (Biologically Appropriate Raw Food) splits the daily ration as 70% muscle meat, 10% raw meaty bone, 10% organ (half liver, half secreting organ), 5% vegetables, and 5% other items such as eggs or fish. PMR (Prey Model Raw) removes the plant matter entirely and runs closer to 80% muscle meat, 10% bone, and 10% organ, reasoning that dogs digest protein and fat more efficiently than plant fiber. If you are tracking puppy weight milestones alongside raw feeding, the BARF model tends to be more flexible because the vegetable fraction can be swapped for organ to cover specific micronutrient gaps during rapid growth phases. Before switching a pregnant or nursing female, check the dog pregnancy calculator to align portion increases with gestational weeks, since caloric needs rise steeply in the final trimester regardless of which model you follow.
Neither model is universally superior. BARF produces better compliance in tracking coat quality and stool consistency because the plant fraction provides prebiotic fiber. PMR appeals to owners who want a simpler shopping list and argue dogs evolved without vegetable matter. The calculator above uses BARF percentages for the component breakdown, but the daily total in ounces and grams applies to both; only the internal distribution changes between frameworks.
A raw-fed puppy at 10 weeks needs 10% of its current body weight per day, a number that sounds high until you consider that puppies can double their weight in weeks. That percentage drops gradually as the dog approaches adult size, typically transitioning to the adult 2% rate somewhere between 12 and 18 months depending on breed. The drop is not linear: a large-breed puppy at 6 months may still need 5-6% while a small breed at the same age may already be near 2.5%. Weigh your dog every two weeks and recalculate rather than assuming last month's portion still applies. If you want to track the grocery spend as portions shift, use a food cost calculator alongside this tool to budget for the higher-volume puppy phase before it arrives.
Senior dogs generally drop to 1.5% of body weight because metabolic rate and activity both decline. The more important adjustment for seniors is the organ-to-muscle ratio: aging dogs process rich organ meats less efficiently, so many experienced raw feeders reduce liver to 3-4% of the daily ration and supplement with fish oil instead to maintain coat condition without the excess vitamin A that full liver portions carry at lower calorie targets.
