Raw Dog Food Calculator

Estimate a raw (BARF) feeding portion as a percent of body weight.

How the Math Works

The Raw Dog Food Calculator uses a straightforward mathematical formula to determine the appropriate daily portion for your dog. The equation is: grams = weight(kg) x 1000 x percent/100. Here, your dog's weight in kilograms is multiplied by 1000 to convert it to grams, then multiplied by the desired percentage of body weight that should come from raw food, and finally divided by 100 to calculate the actual gram amount. For example, a 20kg dog with a 5% raw food percentage would receive: 20 x 1000 x 5/100 = 1000 grams of raw food daily.

Practical Applications

To use this calculator effectively, first convert your dog's weight to kilograms if measured in pounds (1kg equals approximately 2.2lbs). Next, determine the appropriate percentage based on your dog's activity level, age, and health - generally ranging from 3-10% of body weight for adult dogs. Multiply your dog's weight in kg by 1000, then multiply that result by your chosen percentage and divide by 100. This gives you the exact number of grams of raw food your dog should consume each day, which can be divided into multiple meals as needed.

Day-to-Day Use

This calculator simplifies your dog's nutrition planning by providing precise, measurable portions rather than rough estimates. Knowing exactly how many grams of raw food to feed prevents over or underfeeding, which can lead to weight problems or nutritional deficiencies. The daily gram measurement makes shopping for ingredients easier, as you can plan exactly what meats and organs to purchase. Additionally, having a consistent, calculated feeding routine helps monitor your dog's weight, energy levels, and overall health more effectively than guessing portion sizes.

Worked example

20 kg at 2.5% → 500 g/day.
