raw dog diet calculator

How this raw dog diet calculator works

A raw diet calculator estimates how much food to feed each day based on your dog’s body weight, age, activity, and goal. Most raw feeders start with a percentage of body weight and then adjust up or down based on real-world results.

This tool uses common starting percentages:

• Puppies under 4 months: ~8% of body weight per day
• 4–8 months: ~6%
• 8–12 months: ~4%
• Adults: ~2.5%
• Seniors (around 7+ years): ~2.0% as a baseline

Then it applies simple multipliers for activity level and weight goal. The final result gives you a daily total and a meal-by-meal split.

PMR vs BARF: what’s the difference?

PMR 80/10/10

PMR (Prey Model Raw) usually targets:

• 80% muscle meat
• 10% edible bone
• 10% organs (typically 5% liver + 5% other secreting organ)

BARF 70/10/10/7/3

BARF (Biologically Appropriate Raw Food) often uses a broader mix:

• 70% muscle meat
• 10% edible bone
• 10% organs (again, often 5% liver + 5% other)
• 7% vegetables/fruits
• 3% seeds/nuts or similar extras

Neither model is automatically “perfect.” The best plan is the one that is balanced, safe, and sustainable for your dog and your household.

How to use your numbers correctly

1) Start with the estimate for 2–3 weeks

Use the calculator output as your initial feeding amount. Keep portions consistent before making adjustments.

2) Track body condition, not just scale weight

You should be able to feel ribs easily (with a light fat cover), see a waist from above, and observe a gentle abdominal tuck from the side.

3) Adjust in small steps

• If your dog gains excess fat: reduce daily food by ~5–10%
• If your dog is losing too much weight: increase by ~5–10%
• Recheck every 10–14 days

Safety and nutrition reminders for raw feeding

• Handle raw meat with strict hygiene (clean surfaces, bowls, hands).
• Use appropriate raw meaty bones; never feed cooked bones.
• Avoid relying on a single protein source long-term.
• Rotate proteins and include essential micronutrients.
• Watch calcium/phosphorus balance—especially in growing puppies.
• Introduce new foods gradually to reduce digestive upset.

Frequently asked questions

Can I feed once per day?

Many adults tolerate one meal, but two meals are often easier for digestion and appetite control. Puppies usually need more frequent meals.

Should puppies follow the same ratio as adults?

Not always. Puppies have different growth needs and are more sensitive to mineral imbalances. Work with a qualified professional when formulating puppy diets.

What if stool becomes too hard or chalky?

That can mean too much bone. Reduce bone content and rebalance with more muscle meat and hydration support.

Do I need supplements?

Possibly. Some homemade raw diets miss key nutrients (iodine, vitamin D, manganese, omega-3s, and more). A complete recipe or expert review is the safest path.

Bottom line

A raw dog food calculator can make planning far easier. Use the estimate, monitor your dog closely, and refine portions over time. Consistency, hygiene, and nutritional completeness matter more than chasing a perfect ratio on day one.
