Raw feeding guidelines are based on a percentage of body weight, not calorie counting. The standard starting point for a healthy adult dog is 2-2.5% of their ideal body weight per day. The percentage varies by life stage because activity level, metabolism, and growth rate differ significantly between a 10-week-old puppy and a 10-year-old senior dog.
Daily food = Dog weight x stage percentage Average adult: 2% x body weight = daily raw food Active adult: 2.5% x body weight Puppy: 10% x current body weight
Who Is This Calculator For?
Raw feeding eliminates the guesswork of kibble portion sizes, but getting the daily weight right matters. This calculator uses life-stage percentages to give you a precise daily portion in grams and ounces, plus a full BARF component breakdown.
Dog Owners Starting Raw
Get a clear daily portion before your first raw food purchase so you know exactly how much to buy.
Breeders Managing Multiple Dogs
Calculate correct portions for dogs at different life stages and weights without doing the math for each one.
Veterinary Nutritionists
Quickly verify percentage-based feeding guidelines and share results with clients transitioning to raw.
Puppy Owners
Puppies need 10% of current body weight per day, far more than adults. Get the right amount as your puppy grows.
Sport and Working Dog Handlers
Active dogs need 2.5–3% of body weight. Calculate the correct higher-energy portion for your working dog.
Overweight Dog Owners
Feed to ideal target weight, not current weight. This calculator helps set the correct reduced portion for weight loss.
When Should You Use It?
When starting a dog on a raw diet for the first time
Adjusting portions as a puppy grows toward adult weight
Recalculating after a dog's activity level or health status changes
Planning a weekly raw food shopping list
Checking whether a pre-packaged raw food portion matches the guideline
Example Calculations
Example 1: 25 lb average adult dog, twice daily
Weight: 25 lbs (11.34 kg) Stage: Average Adult @ 2% Daily: 11.34 kg × 2% = 0.227 kg = 227 g = 8.0 oz Per meal (2×): 4.0 oz / 113 g Muscle meat (70%): 5.6 oz / 159 g per day
Example 2: 60 lb active adult dog, twice daily
Weight: 60 lbs (27.2 kg) Stage: Active Adult @ 2.5% Daily: 27.2 kg × 2.5% = 0.68 kg = 680 g = 24.0 oz Per meal (2×): 12.0 oz / 340 g Bone component (10%): 2.4 oz / 68 g per day
Common Mistakes to Avoid
!
Using actual body weight for overweight dogs instead of ideal target weight: this locks in excess calories and stalls weight loss
!
Skipping the organ component: liver and secreting organs provide zinc, vitamin A, and B12 that muscle meat cannot supply alone
!
Cold-turkey switching from kibble to raw: most dogs need a 7–14 day gradual transition to avoid digestive upset
!
Feeding a single protein source long-term: variety in proteins (chicken, beef, lamb, fish) provides broader nutritional coverage
!
Ignoring bone content: too much bone causes hard, chalky stools; too little causes loose stools and calcium deficiency over time
Frequently Asked Questions
The standard guideline is 2-3% of your dog's ideal adult body weight per day. Active dogs lean toward 3%, while less active or senior dogs do better at 1.5-2%. Puppies need roughly 10% of their current body weight per day since they are growing rapidly. These are starting points - monitor your dog's body condition every two weeks and adjust the amount up or down to maintain an ideal lean body weight.

Pro Tip
Start with a single protein source like chicken and feed it exclusively for 2-3 weeks before adding new proteins. This makes it easy to identify any food sensitivities.
