Quick Answer
The Raw Dog Food Calculator estimates daily raw feeding amounts from a dog's weight and life stage, then splits the ration into muscle meat, raw bone, liver, and other organs (plus plant matter for BARF). Adult dogs eat about 2-3% of body weight per day (2.5% for maintenance), using the Prey Model 80/10/5/5 or BARF 70/10/5/5/10 ratios.
Feed an adult dog about 2.5% of its body weight in raw food per day. For a 20-kilogram dog that is roughly 500 grams daily, split into 80% muscle meat, 10% raw bone, 5% liver, and 5% other organs.
Key Takeaways
- Adult dogs eat about 2-3% of body weight in raw food daily (2.5% for maintenance)
- Prey Model Raw splits food 80% muscle, 10% bone, 5% liver, 5% other organs
- BARF reduces muscle to ~70% and adds ~10% vegetables, fruit, and seeds
- Puppies eat much more (4-8% of current weight) and need frequent re-weighing
- Handle raw meat hygienically and consult your vet — raw carries bacterial and balance risks

Formula
Daily Food (g) = Body Weight (kg) × 1000 × Daily %
Where:
- F=Daily raw food amount(grams)
- W_{kg}=Dog body weight(kg)
- p=Daily ration as fraction of body weight (e.g. 0.025)
Worked Examples
30 lb Adult Dog on Maintenance (PMR)
A typical medium adult dog fed Prey Model Raw at the 2.5% maintenance rate, split into two meals.
- 1Convert 30 lb to kg: 30 x 0.4536 = 13.6 kg
- 2Daily food = 13.6 kg x 1000 x 2.5% = 340 g/day
- 3Split into 80/10/5/5: 272 g muscle, 34 g bone, 17 g liver, 17 g other organ
- 4Two meals: 170 g per meal
20 kg Active Working Dog (BARF)
An active dog fed BARF at 3% of body weight, including plant matter.
- 1Daily food = 20 kg x 1000 x 3% = 600 g/day
- 2BARF split: 70% muscle (420 g), 10% bone (60 g), 5% liver (30 g), 5% organ (30 g), 10% plant (60 g)
- 3Two meals: 300 g per meal
10 kg Puppy (4 months, PMR)
A growing puppy fed 8% of current body weight across three meals.
- 1Daily food = 10 kg x 1000 x 8% = 800 g/day
- 2Split into 80/10/5/5: 640 g muscle, 80 g bone, 40 g liver, 40 g organ
- 3Three meals: ~267 g per meal
- 4Re-weigh weekly and reduce % as the puppy grows
Introduction
The Raw Dog Food Calculator works out how much raw food (BARF or Prey Model Raw) to feed your dog each day, then splits that amount into the correct ratio of muscle meat, raw edible bone, liver, other organs, and — for BARF — plant matter. Adult dogs typically eat 2–3% of their body weight per day (about 2.5% for maintenance), while puppies eat more and weight-loss dogs eat less. Raw feeding (also called a species-appropriate diet) aims to mimic the whole-prey diet of wild canids. Always transition gradually and consult your vet, especially for puppies, seniors, or dogs with health conditions. For cooked or kibble feeding, see our dog food calculator.
How the Raw Dog Food Calculator Works
The calculator first finds the total daily amount as a percentage of body weight, then divides it into the recommended component ratios for your chosen diet model.
Enter your dog's weight and choose pounds or kilograms
Pick a life stage / goal — this sets the daily percentage (2–8%)
Choose Prey Model Raw (meat, bone, organ only) or BARF (adds plant matter)
Daily food (g) = body weight in kg x 1000 x daily %
Each component = daily food x its ratio (e.g. 80% muscle meat)
Set meals per day to see the per-meal portion
Feed to your dog's IDEAL body weight, not its current weight, if your dog is over- or underweight. Adjust by monitoring body condition every 2–4 weeks.
How Much to Feed by Life Stage
The daily ration is expressed as a percentage of body weight. Puppies need far more relative to their size because they are growing; adults settle at 2–3%.
| Life Stage / Goal | Daily % | Notes |
|---|---|---|
| Puppy 2-4 months | 8% | Of current weight; re-weigh weekly |
| Puppy 4-6 months | 6% | Reduce gradually as growth slows |
| Puppy 6-8 months | 5% | Approaching adult ratios |
| Puppy 8-12 months | 4% | Transition toward adult amount |
| Adult - weight loss | 2% | Of ideal (target) weight |
| Adult - maintenance | 2.5% | Most pet dogs at a healthy weight |
| Adult - active/working | 3% | High activity or hard keepers |
| Senior / less active | 2% | Lower metabolism; watch weight |
PMR vs BARF: The Component Ratios
Two popular raw-feeding frameworks split the daily food differently. Prey Model Raw (PMR) mimics whole prey with no plants; BARF (Biologically Appropriate Raw Food) adds vegetables, fruit, and seeds.
| Component | PMR (80/10/5/5) | BARF (70/10/5/5/10) |
|---|---|---|
| Muscle meat | 80% | 70% |
| Raw edible bone | 10% | 10% |
| Liver | 5% | 5% |
| Other secreting organs | 5% | 5% |
| Vegetables, fruit & seeds | 0% | 10% |
Liver should be about half of the total organ portion. 'Other secreting organs' means kidney, spleen, pancreas, or brain — NOT muscular organs like heart or gizzard, which count as muscle meat.
Raw Edible Bone Safety
Raw edible bone supplies calcium and phosphorus, but the wrong bones are dangerous. Only soft, raw, weight-bearing-free bones are 'edible'.
Good edible bones: chicken necks, wings, and feet; turkey necks; duck frames; rabbit
Never feed cooked bone — it splinters and can perforate the gut
Avoid dense weight-bearing bones (beef femur) for eating — they crack teeth
Too much bone causes white, crumbly, constipated stools; too little causes loose stools
Adjust bone up or down by ~2% based on stool firmness
Always supervise dogs eating bone and feed appropriately sized pieces
Transitioning to Raw Safely
Switching to raw too quickly can cause digestive upset. Introduce proteins one at a time over 1–2 weeks.
Start with a single, lean, easy protein (e.g. chicken) for several days
Begin with muscle meat only; add bone after a few days, then organs last
Introduce one new protein every 4–7 days once stools are firm
Add organs slowly — liver especially can loosen stools if rushed
Keep meals slightly cool, not frozen solid, and practice strict hygiene
Watch for vomiting, diarrhea, or itching that may signal intolerance
Feed adult dogs raw on an empty-ish stomach and avoid mixing raw and kibble in the same meal during transition, since they digest at different rates.
Food Safety and Who Should Be Careful
Raw diets carry real benefits but also risks that responsible owners must manage. The FDA and many vets caution about bacterial pathogens.
Handle raw meat like you would for humans: wash hands, surfaces, and bowls thoroughly
Raw diets can carry Salmonella, Listeria, and E. coli — a risk to both pets and people
Households with infants, elderly, or immunocompromised members should take extra care
Source meat from reputable suppliers; freeze fish and pork to reduce parasite risk
A poorly balanced raw diet can cause nutrient deficiencies — follow ratios and rotate proteins
Consult your vet before starting raw for puppies, pregnant dogs, or dogs with illness
This calculator provides general portioning guidance. It is not veterinary advice — work with your vet or a qualified canine nutritionist for a fully balanced plan.

FAQs
How much raw food should I feed my dog?
Adult dogs typically eat 2-3% of their body weight per day, with 2.5% being a good starting point for maintenance. For example, a 20 kg (44 lb) adult dog eats about 500 g per day. Active or working dogs may need 3%, while dogs needing to lose weight get about 2% of their ideal weight. Puppies eat far more relative to size — from 8% at 2-4 months down to about 4% by their first birthday.
What is the 80/10/10 rule for raw dog food?
The 80/10/10 rule (Prey Model Raw) splits the daily food into 80% muscle meat, 10% raw edible bone, and 10% organs. The organ portion is usually divided as 5% liver and 5% other secreting organs (like kidney), which is why it's often written 80/10/5/5. This ratio mimics the composition of whole prey animals that wild canids would eat.
What is the difference between BARF and Prey Model Raw?
Prey Model Raw (PMR) feeds only animal parts — 80% muscle meat, 10% bone, 5% liver, 5% other organs — to mimic whole prey. BARF (Biologically Appropriate Raw Food) keeps similar meat ratios but reduces muscle meat to about 70% and adds roughly 10% vegetables, fruit, and seeds. BARF supporters value the extra fiber and phytonutrients; PMR supporters argue dogs need little plant matter.
How do I feed a raw diet to a puppy?
Puppies are fed a higher percentage of their current body weight: about 8% at 2-4 months, 6% at 4-6 months, 5% at 6-8 months, and 4% at 8-12 months, re-weighing weekly and reducing the percentage as they grow. They need the same 80/10/5/5 (or BARF) ratios but with extra attention to calcium from bone for proper skeletal development. Always involve your vet when raw-feeding a growing puppy.
Should I feed based on current or ideal weight?
Feed to your dog's ideal (target) body weight, especially for weight loss or gain. If your dog is overweight, calculating from its current weight would just maintain the excess. Estimate the ideal weight (your vet can help), use the 2% weight-loss rate, and reassess body condition every 2-4 weeks, adjusting the amount as needed.
How many meals a day should a raw-fed dog eat?
Adult dogs do well on two meals per day; some owners feed once daily. Puppies need more frequent meals — three to four per day for young pups — because of their small stomachs and high energy needs. The calculator divides the daily ration by your chosen number of meals so you know the per-meal portion.
Is raw feeding safe for dogs?
Raw feeding can be done safely but carries risks. Raw meat can harbor Salmonella, Listeria, and E. coli, which can affect both pets and people, so strict hygiene is essential. A poorly balanced raw diet can also cause nutrient deficiencies. The FDA and many vets advise caution, particularly in homes with infants, elderly, or immunocompromised people. Source quality meat, follow the ratios, rotate proteins, and consult your vet.
How much bone should be in raw dog food?
Raw edible bone should make up about 10% of the diet. Too much bone causes hard, white, crumbly stools and constipation; too little causes loose stools. Use your dog's stool as a guide and adjust bone by roughly 2% in either direction. Only feed soft, raw edible bones like chicken necks, wings, and feet — never cooked bone, which splinters dangerously.
Can I mix raw food and kibble?
Many owners feed raw and kibble at different meals successfully. However, mixing them in the same meal is debated because they digest at different rates, which may upset some dogs' stomachs during transition. If you want to combine, feed kibble and raw several hours apart, and watch your dog's digestion. When fully transitioned, plenty of dogs tolerate mixed feeding fine.
Do raw-fed dogs need supplements?
A properly balanced and varied raw diet — with correct organ and bone ratios and rotated proteins — supplies most nutrients. Common additions include oily fish or fish oil for omega-3s, and some owners add vitamin E, kelp (iodine), or eggshell if bone is limited. Needs vary by individual, so consult a vet or canine nutritionist rather than guessing, especially for long-term feeding.
