Work out how much raw food your dog needs each day as a percentage of body weight, adjusted for age, activity and weight goals. The plan splits the amount into muscle meat, raw meaty bone, liver and other organ for prey model or BARF feeding.

Weight loss is based on the ideal, not the current, weight.
Optional, used for a check: puppies usually eat 2–3% of adult weight at minimum.

How to use the Raw Dog Food Calculator
Enter your dog's current weight and choose kg or lb.
Pick the age bracket; puppies use a higher percentage of their current weight.
Choose activity and weight goal for adult dogs (add the ideal weight for weight loss).
Select the diet model and the number of meals per day.
Press Calculate raw food to see the daily amount and the meat, bone and organ breakdown.
How the raw feeding amount is calculated
daily raw food = body weight × feeding percentage. The calculator suggests a percentage from age and activity, then splits the total by your diet model.
Example: a 25 kg adult dog with normal activity at 2.5%: 25,000 g × 0.025 = 625 g per day, or about 312 g per meal on two meals. With prey model 80/10/5/5 that is 500 g muscle meat, 62.5 g bone, 31 g liver and 31 g other organ.

Bone % means edible bone content, not the weight of meaty bones: a chicken wing is only about 40–50% bone. Watch the stool: too firm and pale usually means too much bone, too loose means too little bone or too much organ.
Frequently asked questions
How much raw food should I feed my dog?
Most adult dogs eat about 2 to 3 percent of their body weight in raw food per day. A 25 kg dog at 2.5 percent eats about 625 g a day. Less active or senior dogs need nearer 2 percent, very active or working dogs 3 to 3.5 percent.
How much raw food does a puppy need?
Growing puppies need much more per kilogram than adults. A common guide is about 8 to 10 percent of current weight at 2 to 4 months, 6 to 8 percent at 4 to 6 months, 4 to 6 percent at 6 to 9 months and 3 to 4 percent at 9 to 12 months, adjusted by body condition.
What is the 80/10/5/5 ratio?
It is the prey model raw ratio: 80 percent muscle meat, 10 percent edible raw bone, 5 percent liver and 5 percent another secreting organ such as kidney or spleen. BARF uses about 70/10/5/5 and adds roughly 10 percent vegetables, fruit and seeds.
Should I feed based on current or ideal weight?
For maintenance, use the current weight if your dog is in good shape. For weight loss, feed a percentage of the ideal target weight, which the calculator does when you choose Lose weight and enter the ideal weight.
Is this amount exact?
No. Metabolism, breed, neutering and the fat content of the meat all change real needs. Weigh your dog every couple of weeks and adjust the amount by 10 percent if it gains or loses weight you did not want. Talk to your vet before switching to raw feeding.
Which bones are safe in a raw diet?
Raw meaty bones that the dog can chew, such as chicken necks, wings or backs for most dogs, are typical. Never feed cooked bones, which splinter. Weight-bearing bones of large animals are very hard and can damage teeth.
