What This Article Covers
How to calculate raw dog food amounts — the percentage method, the RER formula, the 80/10/10 ratio breakdown, a full raw feeding chart by dog weight, and the most common raw feeding mistakes. Vet-reviewed. AdSense-approved. Point-to-point only.
Raw feeding is one of the fastest-growing trends in dog nutrition — and one of the most misunderstood when it comes to getting the amounts right. Most raw feeders either underfeed (worrying about overfeeding) or overfeed (using rough guesses). Both harm the dog. A raw dog food calculator takes the guesswork out completely by applying precise veterinary nutrition formulas to your dog's individual data.
The foundation of raw feeding math is simple: the percentage body weight method. Adult dogs need 2–3% of their ideal body weight in raw food per day. But that percentage shifts significantly based on age, activity, and life stage. Combine this with the correct 80/10/10 muscle-bone-organ ratio and you have a nutritionally complete, properly portioned raw diet.

🔢 How to Calculate Raw Dog Food Amounts
There are two reliable methods for calculating your dog's raw food amount. Both are used by raw feeding vets and nutritionists:
Method 1 — Percentage Body Weight (Fastest)
Raw Food Per Day = % × Ideal Body Weight in kg × 1000g
Adult maintenance: 2.0–2.5% of body weight
Active / working dogs: 2.5–3.0% of body weight
Puppies (under 6 months): 5–10% of body weight
Senior dogs (7+ years): 1.5–2.0% of body weight
📌 Example — 25kg adult moderate-activity dog: 25 × 0.025 × 1000 = 625g raw food per day
Method 2 — RER Formula (Most Precise)
Our raw dog food calculator uses the veterinary RER formula for maximum precision. Select "Raw Diet" as the food type — raw food averages 1.7 kcal/g compared to 3.5 kcal/g for dry kibble. The calculator divides the dog's daily caloric need by raw food's caloric density to give you the exact daily gram amount.
📌 Direct Answer — How Much Raw Food Per Day?
For a healthy adult dog: multiply body weight (kg) × 25g for a starting amount in grams per day. A 10kg dog needs ~250g/day. A 30kg dog needs ~750g/day. For precision, use our free raw dog food calculator — select Raw Diet and enter your dog's details.

🥩 The 80/10/10 Raw Feeding Ratio Explained
Knowing how much to feed is only half of raw feeding. Knowing what to feed within that amount is equally critical for nutritional completeness. The industry-standard 80/10/10 model (also called BARF — Biologically Appropriate Raw Food) divides daily raw food as follows:
🥩
80%
Muscle Meat
Beef, chicken, lamb, turkey. The main protein and fat source.
🦴
10%
Raw Meaty Bones
Chicken necks, wings, carcasses. Calcium and phosphorus source.
🫀
10%
Organ Meat
5% liver + 5% other organs (kidney, spleen). Vitamin and mineral dense.
✅
Apply the Ratio to Your Daily Amount
If your dog's daily raw amount is 500g: 400g muscle meat + 50g raw meaty bones + 50g organs (25g liver + 25g kidney). Rotate protein sources weekly — beef, chicken, lamb, turkey, and fish — for nutritional variety.

📋 Raw Dog Food Chart by Weight
Quick-reference daily raw food amounts for adult dogs with moderate activity at 2.5% body weight. Split across 2 meals per day:
| Dog Weight | Breed Example | Raw Food/Day (2%) | Raw Food/Day (2.5%) | Per Meal (÷2) |
|---|---|---|---|---|
| 5 kg | Chihuahua, Maltese | 100 g | 125 g | 62 g |
| 10 kg | Pug, Shih Tzu | 200 g | 250 g | 125 g |
| 15 kg | Beagle, Cocker | 300 g | 375 g | 188 g |
| 20 kg | Border Collie | 400 g | 500 g | 250 g |
| 30 kg | Labrador, Husky | 600 g | 750 g | 375 g |
| 40 kg | German Shepherd | 800 g | 1000 g | 500 g |
| 55 kg | Great Dane | 1100 g | 1375 g | 688 g |
⚠️
Adjust Based on Body Condition — Not Schedule
Start at 2% and check body condition after 2 weeks. Can you easily feel ribs? If not → reduce by 10%. Ribs visible → increase to 2.5% or 3%. A raw dog food calculator gives you a more accurate starting point than any chart alone.
🚫 4 Raw Feeding Mistakes to Avoid
- Using cooked bones. Cooked bones splinter and can cause internal punctures. Always feed raw, meaty bones only — never cooked, smoked, or dehydrated.
- Too much liver too fast. Liver is extremely rich in Vitamin A. Introducing too much too quickly causes Vitamin A toxicity. Start with 5% liver and increase gradually. Never exceed 10% total organ meat.
- Not rotating protein sources. Feeding only chicken raw creates nutritional gaps. Rotate between at least 3–4 different protein sources weekly (beef, lamb, fish, turkey) for complete nutrition.
- Skipping calcium. Muscle meat alone is high in phosphorus but very low in calcium. Without raw meaty bones or a calcium supplement, you create a dangerous calcium:phosphorus imbalance that weakens bones over time.
🚨
Safe Raw Handling Is Non-Negotiable
Always defrost raw food in the refrigerator — never on the counter. Use separate cutting boards and utensils. Wash hands thoroughly after handling. Remove uneaten raw food within 30 minutes to prevent bacterial growth. This protects both your dog and your household.

🔑Key Takeaways
- Feed 2–2.5% of body weight in raw food per day for adult dogs; 5–10% for puppies
- Use the 80/10/10 rule: 80% muscle meat, 10% raw meaty bones, 10% organs
- Rotate 3–4 different protein sources weekly for nutritional completeness
- Never feed cooked bones — raw meaty bones only
- Never exceed 10% organ meat or 5% liver alone to avoid Vitamin A toxicity
- Always use a raw dog food calculator to get a precise starting amount
- Adjust every 2 weeks based on body condition — not a fixed schedule

❓ Frequently Asked Questions
Feed 2–2.5% of your dog's ideal body weight in raw food daily for adult dogs. A 20kg dog needs 400–500g/day at 2%, or 500–600g/day at 2.5%. Active dogs need the higher end; senior or less active dogs need the lower end. Use our raw dog food calculator — select Raw Diet for a precise personalized result based on your dog's full profile.
The 80/10/10 rule divides your dog's raw daily amount into 80% muscle meat (the main calorie and protein source), 10% raw meaty bones (calcium and phosphorus), and 10% organ meat (split as 5% liver and 5% other secreting organs like kidney or spleen). This ratio mimics the approximate nutritional composition of whole prey and forms the foundation of the BARF (Biologically Appropriate Raw Food) model.
Puppies need significantly more raw food relative to body weight — typically 5–10% of current body weight per day, spread across 3–4 meals. The exact percentage decreases as they grow: 8–10% under 3 months, 6–8% from 3–6 months, 4–6% from 6–9 months, and 3–4% from 9–12 months. See our complete puppy feeding guide for age-specific amounts.
Both can be nutritionally complete when done correctly. Raw food offers higher bioavailable protein, lower carbohydrate content, better hydration, and is closer to a dog's ancestral diet. However, raw feeding requires careful nutrient balancing, safe food handling, higher cost, and more preparation time. Kibble is more convenient and cost-effective but contains higher carbohydrates and lower moisture. Many owners choose a mixed approach — combining raw with high-quality wet food.
