The gap this page fills
Search for a raw dog food calculator and what you get is a long list of brand sites: each one asks for your dog's weight, returns a daily total in grams or pounds, and then steers you toward a subscription box or a specific product line. The arithmetic is correct as far as it goes, but it only goes one step — the total — and it is wrapped in a sales funnel.
This page does the opposite. It treats the calculator as the product, not the hook. You get the daily total, but you also get the breakdown into muscle meat, edible bone and organ, because a raw diet that hits the total without hitting the ratios is not a balanced raw diet. You get a calorie reality-check against the same veterinary RER formula the dog calorie calculator uses, because "2% to 3% of body weight" is a rule of thumb that assumes a particular energy density, and real raw recipes vary. And you get the numbers without handing over an email address or creating an account.
The reference tools that dominate the dog-calorie results do not cover raw feeding at all. The Pet Nutrition Alliance calorie calculator and the Association for Pet Obesity Prevention calculators both stop at a daily calorie figure for commercial food and never reach the question of how that translates into grams of raw meat and bone.
Prey model vs BARF: what the ratios actually mean
Both models start from the idea that a dog eating raw should approximate the composition of whole prey. The difference is how strictly they follow that idea.
Prey model (80/10/10) tries to replicate a whole small animal: roughly 80% muscle meat, 10% edible bone and 10% organ, with half the organ being liver and the other half secreting organs like kidney or spleen. There are no vegetables, no fruit and no grains. The argument is that wolves do not eat plant matter in significant quantities, and dogs do not need it either.
BARF (70/10/10/10) keeps the same meat, bone and organ proportions but adds roughly 10% vegetables and fruit, often pureed or lightly processed to break down cell walls. The argument here is that modern dogs have adapted to some plant matter, and that vegetables provide fibre and micronutrients that are hard to source from meat alone.
The calculator lets you choose either model, or enter your own percentages if you are working with a veterinary nutritionist's custom recipe. The numbers are a starting point, not a prescription: individual dogs vary, and the only way to know whether a particular ratio is working is to watch body condition, coat quality and energy level over several weeks.
Why the 2–3% rule is only a starting point
The most common rule of thumb in the raw-feeding community is to serve roughly 2% to 3% of the dog's body weight per day. That range works as a first guess for a moderately active adult on a typical lean meat-and-bone mix, but it is an approximation, not a standard.
The rule silently assumes an energy density of about 1.3 to 1.6 kcal per gram of raw food. We built that estimate from USDA FoodData Central values for common raw ingredients: skinless chicken breast at about 1.2 kcal/g, 85% lean ground beef at about 2.15 kcal/g, beef liver at about 1.35 kcal/g, and edible bone (mostly collagen and minerals) at roughly 0.8 kcal/g. A prey-model mix of 80% meat, 10% bone and 10% organ lands in the middle of that band, but the moment you swap in fattier cuts or add oil the density climbs; swap in leaner poultry or bulk with vegetables and it drops. The calculator above accounts for that by checking the portion against the dog's actual MER.
The rule also ignores lifestyle. A working sled dog and a couch-bound spaniel of the same weight have different energy needs by a factor of two or more. The calculator above adjusts the percentage for activity level, growth stage and weight goals, then checks the result against a veterinary MER estimate so you can see whether the gram total and the calorie target line up.
A raw food calculator dog owners can run without signing up
Most of the raw food calculators that rank well are built by brands. They work, but they are designed to collect a lead — an email, a pet profile, a subscription — before they show you the full breakdown. The free version often gives you a single number, and the detailed ratios sit behind a paywall or a product recommendation.
This tool is different: it is a raw food calculator dog owners can use immediately, with no account, no email and no upsell. You enter a weight and a lifestyle, pick a model, and you get the full breakdown in grams: muscle meat, bone, organ and vegetables. The calorie check runs alongside, so you can see whether the portion is likely to maintain, gain or lose weight. If you want to save the result, screenshot it or write it down — the calculator does not store anything server-side.
Raw food diet for dogs calculator: prey model or BARF
If you are trying to decide between prey model and BARF, the calculator above is the fastest way to see what each model looks like in grams for your specific dog. Switch the model dropdown from prey to BARF and watch the vegetable line appear; the total grams stay the same, but the composition shifts.
The choice between the two is less about mathematics and more about philosophy and individual tolerance. Some dogs digest raw vegetables well and produce firmer stools with BARF; others do better on prey model alone. Some owners find prey model simpler because there is no vegetable prep; others prefer BARF because they believe the fibre and phytonutrients matter. The calculator does not take sides — it just gives you the numbers for whichever model you are running.
For owners who want to cook instead of feed raw, the homemade dog food calculator handles cooked recipes with the same ingredient-level approach, accounting for cooking yield so the portion in grams reflects the food as it goes into the bowl.
Puppy raw food calculator: why the adult ratio breaks
Puppies need more food per unit of body weight than adults because they are building tissue, not just maintaining it. A common approximate guideline in raw-feeding circles is 8% to 10% of body weight per day for a puppy under four months, dropping to 5% to 8% from four to twelve months, after which the adult 2% to 3% range applies. Those percentages are starting points, not standards — individual growth rates vary by breed and litter, so the calculator treats them as adjustable defaults and ties them back to the same veterinary MER estimate used for adults.
The calculator above applies those percentages automatically when you select a puppy stage, and it breaks the total down into the same prey-model or BARF ratios. The organ portion matters especially for puppies: liver supplies vitamin A and copper that are critical for growth, and bone supplies calcium and phosphorus in the ratio a growing skeleton needs. Puppies on raw should not be rationed from an adult recipe without adjusting both the total grams and the mineral balance.
For a calorie-first view of puppy feeding that works across both raw and cooked diets, see the puppy calorie calculator.
Frequently asked questions
How much raw food should I feed my dog per day?
Start with 2% to 3% of body weight for a typical adult, then adjust for activity and body condition. The calculator above does that adjustment automatically and breaks the total into muscle meat, bone and organ.
Is 2% to 3% of body weight enough for raw food?
For many adults, yes — but it depends on the recipe's fat content and the dog's activity level. A very lean recipe or a very active dog may need 3% to 4%; an overweight, inactive dog may do well on 1.5% to 2%. Use the calculator's calorie check to see whether the gram total matches the dog's energy needs.
What is the 80/10/10 rule for raw dog food?
It is the prey-model breakdown: roughly 80% muscle meat, 10% edible bone and 10% organ, with half the organ being liver. The idea is to mimic the composition of whole prey. It is a guideline, not a rigid rule — some dogs tolerate more bone, others need less.
Can I feed raw and kibble in the same day?
Many owners do, but the two foods digest at different rates and some dogs get loose stools when they are mixed in the same meal. If you want to combine them, serve them in separate meals several hours apart, and recalculate the raw portion so you are not double-feeding calories.
How do I switch my dog to raw food?
Gradually, over one to two weeks. Start by replacing 25% of the current food with raw, then move to 50%, 75% and finally 100%, watching stool quality and energy at each step. Puppies and dogs with sensitive stomachs may need a slower transition. Do not switch a dog with a known health condition without veterinary guidance.
What counts as edible bone?
Raw, non-weight-bearing bones that a dog can crunch and digest: chicken necks, wings and backs; turkey necks; rabbit bones. Avoid cooked bones of any kind — they splinter. Weight-bearing bones from large animals (beef femurs, for example) are too hard and can fracture teeth.
Do I need to add supplements to a raw diet?
A well-constructed prey-model or BARF diet covers most needs through whole foods, but many recipes are short of vitamin E, zinc and iodine. A veterinary nutritionist can review your specific recipe and recommend targeted supplements rather than a generic multivitamin.
How is raw different from homemade cooked food?
Raw food retains its natural moisture and enzyme content and typically has a higher energy density per gram than cooked food, because no water is lost in cooking. A cooked chicken-and-rice recipe is often around 1.2 kcal per gram; raw chicken with bone is closer to 1.3 to 1.6. That is why raw portions are usually smaller in gram weight than cooked portions for the same calorie target. The homemade dog food calculator handles the cooked side with cooking-yield arithmetic.
