BARF Feeding Calculator (Dogs)
BARF = Biologically Appropriate Raw Food. Enter your dog’s details to estimate daily food amount and macro split.

What is a BARF calculator?
A BARF calculator helps you estimate how much raw food to feed your dog each day using a percentage of body weight. Instead of guessing portions, you can build a structured feeding plan based on your dog’s size, life stage, and activity level. This calculator also breaks the total into typical BARF components: muscle meat, edible bone, liver, other organ, and optional produce.
How this calculator works
1) Daily quantity
The first step is estimating total food per day. A common rule is to feed a percentage of body weight:
- Adult maintenance: around 2%–3%
- Active dogs: around 3%–4%
- Puppies: often 5%–8% (varies by age/growth phase)
- Weight loss: often lower than maintenance
The calculator multiplies your dog’s body weight by your selected feeding percentage to estimate daily grams. It then divides that amount by meals per day.
2) Ratio breakdown
After computing total daily food, the calculator splits it by your chosen BARF ratios. A common template is:
- 70% muscle meat
- 10% edible bone
- 5% liver
- 5% other secreting organ
- 10% vegetables/fruit (optional in some raw approaches)
Not every raw-feeding philosophy uses produce, and some use prey-model ratios instead. Use the ratio pattern that matches your veterinarian or nutrition professional’s guidance.
Why consistency matters
Dogs do best when meals are consistent and adjustments are gradual. Sudden swings in portion size or ingredient composition can cause digestive upset. Use calculator numbers as a starting point, then monitor body condition, stool quality, energy, and coat health over time.
Signs you may need to adjust portions
- Unintended weight gain or loss over multiple weeks
- Persistent loose stool or constipation
- Low energy, poor recovery, or increased hunger
- Changes in muscle tone or body condition score
Safety and nutrition notes
Raw feeding requires careful sourcing, hygiene, and nutrient planning. Wash hands and surfaces, keep cold-chain storage reliable, and avoid unsafe bones. Also remember that “balanced over time” still needs structure. Nutrients such as calcium/phosphorus ratio, omega-3 intake, iodine, zinc, copper, and vitamins A/D/E should be considered.
This tool is educational and not a medical diagnosis or a complete veterinary nutrition plan. If your dog is a puppy, pregnant, lactating, elderly, or has kidney, liver, GI, endocrine, or orthopedic conditions, consult a veterinarian (ideally one with nutrition training) before changing diet.
Quick usage checklist
- Enter accurate current body weight.
- Choose an appropriate feeding goal and percentage.
- Set realistic meals per day.
- Confirm ratios total 100%.
- Track your dog for 2–4 weeks and adjust gradually.
Frequently asked questions
Is this calculator for puppies?
Yes, but puppy growth is dynamic. Re-check weight frequently and review feeding amounts often. Large-breed puppies especially need careful mineral balance.
Should I feed exactly the same amount every day?
Use the estimate as your baseline. Small day-to-day variation is fine, but avoid drastic changes unless directed by a vet.
Can I use pounds instead of kilograms?
Yes. The calculator accepts both and converts internally for accurate gram outputs.
