If you feed a raw diet, portion size is the first thing to get right. This calculator gives you a practical daily feeding estimate based on your dog’s weight, life stage, activity level, body-weight goal, and raw feeding model. Use it as a starting point, then adjust based on your dog’s condition over time.

Note: Estimates are starting points. Monitor body condition, stool quality, energy levels, and adjust weekly.
How this raw feeding calculator works
Most raw plans are based on a percentage of body weight. For example, many adult dogs start around 2% to 3% of body weight per day, while puppies often need more. This tool applies a base percentage by life stage, then adjusts up or down for activity and your feeding goal.
- Life stage: Puppies and younger dogs generally need a higher percentage.
- Activity: Highly active or working dogs typically need more food.
- Goal: Weight-loss plans usually reduce intake slightly; weight gain plans increase it.
- Model: You can split your daily total into common prey model or BARF ratios.
Typical raw feeding percentages
These are broad, practical ranges used by many raw feeders and nutrition-minded owners:
- Puppy (2-6 months): often around 5% to 8% of body weight daily.
- Juvenile (6-12 months): often around 3% to 5% daily.
- Adult: often around 2% to 3% daily.
- Senior: often around 1.5% to 2.5% daily depending on body condition and activity.
There is no single perfect number for every dog. Breed, metabolism, neuter status, climate, and exercise routine all matter.
Prey Model vs BARF split
Prey Model Raw (PMR)
- 80% muscle meat
- 10% edible bone
- 5% liver
- 5% other secreting organs
BARF Model
- 70% muscle meat
- 10% edible bone
- 5% liver
- 5% other secreting organs
- 10% vegetables/fruit/seeds (as tolerated)
Both models are common. Your dog’s digestion, stool consistency, and bloodwork trends can help guide which approach works best.
How to transition to raw food safely
1) Start simple
Begin with one easy-to-digest protein and keep meals consistent for several days before introducing variety.
2) Introduce organs slowly
Organs are nutrient-dense and can loosen stool if added too quickly. Increase in small increments.
3) Track your dog weekly
- Body weight
- Body condition score (ribs, waist, abdominal tuck)
- Energy and behavior
- Stool quality and frequency
4) Recalculate after changes
Adjust portions when your dog’s routine changes: more exercise, less exercise, weather shifts, growth spurts, or health changes.
Food safety checklist for raw feeding
- Keep raw ingredients refrigerated or frozen properly.
- Thaw safely in the fridge, not on the counter.
- Sanitize prep surfaces, utensils, and bowls.
- Wash hands thoroughly after handling raw meat.
- Use species-appropriate, quality ingredients.
Common mistakes to avoid
- Feeding too much bone (can cause dry, chalky stool).
- Skipping organ variety entirely.
- Not adjusting portions when activity changes.
- Relying on one protein source forever.
- Ignoring long-term monitoring and veterinary input.
Final note
A raw food diet can be done thoughtfully, but precision matters. Use this calculator as your baseline, then fine-tune with observation and professional guidance. If your dog has chronic medical issues, growth concerns, kidney disease, pancreatitis history, or gastrointestinal sensitivity, work with your veterinarian or a qualified canine nutrition professional before making major dietary changes.
