How much to feed
How do I measure a portion of raw dog food?
Last updated 23 September 2026 · How we write and check this
Short answer
Raw food portions are usually calculated as a percentage of body weight, commonly around 2 to 3 percent for an adult dog's daily total, rather than through the resting energy formula used for dry food, because raw diets vary widely in fat and calorie content between recipes. Weigh the food in grams and start at 2.5 percent of body weight as a reasonable middle point, then adjust based on body condition.
Why raw feeding uses a different method
Calorie content in raw food varies considerably depending on the meat, organ, and fat content of a given recipe, which makes a precise calorie based calculation harder to apply consistently compared to a bagged dry food with a printed calorie count.
The percentage of body weight method gives a workable starting point that many raw feeding guides use, generally 2 to 3 percent of the dog's ideal adult weight per day.
Working out the amount
For a 20kg dog, 2.5 percent of body weight works out to 500g a day, typically split across one or two meals depending on the dog's routine.
A more active or working dog may need closer to 3 percent, while a lower energy dog may do better nearer 2 percent, similar to the activity adjustments used for other food types.
Checking the amount is working
Weigh your dog every two to three weeks and check the waist and ribs, adjusting the percentage up or down by 0.25 percent at a time if the trend runs the wrong way.
If you are new to raw feeding, a raw food supplier or a vet with raw feeding experience can help confirm the recipe you are using provides balanced nutrition alongside the correct total amount, since getting the overall balance right matters as much as getting the daily quantity right.
Key takeaways
- Raw food is commonly measured as a percentage of body weight, often 2 to 3 percent a day for an adult dog.
- 2.5 percent of ideal body weight is a reasonable starting point to adjust from.
- More active dogs often need closer to 3 percent, lower energy dogs closer to 2 percent.
- Check body condition every two to three weeks and adjust the percentage in small steps.
