If you've spent any time reading about raw feeding, you've seen the numbers 80/10/10. They're the foundation of prey-model raw (PMR) feeding, and once they click, most of raw feeding gets a lot simpler.
What the numbers mean
- 80% muscle meat — the bulk of the diet. This includes heart and tongue, which are muscles, not organs.
- 10% edible bone — raw, consumable bone like chicken necks or wings, for calcium and structure.
- 10% organ meat — half of which (5% of the total) should be liver, with the rest from other secreting organs like kidney or spleen.
Balance over time, not per meal
You don't need every bowl to be perfectly 80/10/10. Dogs balance over days, not meals. Aim to hit the ratios across a week and you'll be in great shape. This is why batch prep works so well — you can portion a week of balanced meals at once.
Where people go wrong
The two most common mistakes are too much bone (which causes hard, chalky, constipated stools) and too much organ (which causes loose stools). Both are easy to correct once you know what to look for — your dog's poop is the fastest feedback loop you have.
Doing this math by hand for every protein gets old fast. The FreshFed Feeding System has a built-in Ratio Builder that balances 80/10/10 (and other models) automatically — just enter your ingredients. Want a quick portion estimate first? Try the free Calorie Calculator.
