What is the Raw Dog Food Calculator?
This calculator estimates how much raw food (a BARF or prey-model diet) to feed your dog each day. Raw feeding portions are based on a percentage of your dog's body weight, so the tool converts your dog's weight into grams and applies the daily feeding rate you choose.
How to use it
Enter your dog's current weight in kilograms and the daily feeding rate as a percentage of body weight. Most adult dogs at a healthy weight eat 2–3% per day. Use a lower figure for overweight or sedentary dogs and a higher one for active, working, or growing dogs. The calculator returns the total daily grams, the amount per meal if you feed twice a day, and a weekly total to help with bulk meal prep.
The formula explained
The core formula is $$\text{Daily grams} = \text{Weight}_{kg} \times 1000 \times \frac{\text{Feeding \%}}{100}$$ Multiplying by 1000 converts kilograms to grams, and dividing the percentage by 100 turns it into a decimal fraction. For example, 2.5% becomes \(0.025\).
Worked example
A 10 kg adult dog fed at 2.5% needs $$10 \times 1000 \times 0.025 = 250 \text{ grams}$$ per day. Split into two meals that's 125 g each, or 1,750 g across a week.
FAQ
What feeding percentage should I use? Start at 2.5% for an average adult dog and adjust over a few weeks based on weight and condition.
How much for puppies? Puppies typically eat 5–10% of their current body weight, decreasing as they mature. Always feed according to expected adult weight where guidance suggests.
Is this veterinary advice? No. This tool gives a general starting point. Consult your vet for medical conditions, pregnancy, or a properly balanced raw diet.
