Most adult dogs on a raw diet need 2% to 3% of their ideal body weight in food per day. A 50-pound dog, for example, would eat 1 to 1.5 pounds of raw food daily. That range gives you a starting point, but the exact amount depends on your dog’s age, activity level, body condition, and the type of protein you’re feeding.
The 2–3% Rule Explained
The standard formula is simple: multiply your dog’s ideal body weight by 0.02 for the low end and 0.03 for the high end. That gives you a daily range in pounds. Less active, older, or overweight dogs typically do well closer to 2%. Active dogs, dogs with fast metabolisms, and underweight dogs usually need closer to 3% or occasionally more.
The key word here is “ideal” body weight. If your dog currently weighs 70 pounds but should weigh 60, you’d calculate based on 60 pounds. This naturally creates a calorie deficit that supports gradual weight loss without leaving your dog nutritionally short. For a 60-pound target, that’s 1.2 to 1.8 pounds of food per day.
Some dogs genuinely need less than 2%. If your dog becomes a picky eater or starts leaving food in the bowl, that’s often a sign of overfeeding, especially common when people first switch to raw. Try reducing portions slightly and see if appetite improves.
Quick Reference by Body Weight
- 10-pound dog: 3.2 to 4.8 ounces per day
- 25-pound dog: 8 to 12 ounces per day
- 50-pound dog: 1 to 1.5 pounds per day
- 75-pound dog: 1.5 to 2.25 pounds per day
- 100-pound dog: 2 to 3 pounds per day
These are daily totals, split across however many meals you feed.
How Protein Type Changes the Amount
Not all raw proteins are equally calorie-dense, which means the same weight of food can deliver very different amounts of energy. Beef, lamb, and pork are higher in fat and calories. Chicken, turkey, fish, and especially rabbit are leaner. Rabbit has the highest protein-to-calorie ratio of any common raw protein, while pork is one of the fattiest.
If your dog eats mostly rich proteins like beef or lamb, you may find they do well at the lower end of the 2–3% range. If you’re feeding a lot of lean poultry or rabbit, they might need portions closer to 3%. Watch your dog’s body condition over a few weeks and adjust. You should be able to feel their ribs easily without pressing hard, and they should have a visible waist when viewed from above.
What Goes Into That Daily Amount
The total daily weight needs to be balanced across different types of food, not just muscle meat. Two common frameworks guide how to divide it up.
The Prey Model (PMR)
This approach mimics a whole prey animal and contains no plant matter. The breakdown is 80% muscle meat, 10% raw edible bone, 5% liver, and 5% other secreting organ (like kidney, spleen, or pancreas). It’s the simpler of the two models.
The BARF Model
The Biologically Appropriate Raw Food model adds plant matter. The ratios are 70% muscle meat, 10% raw edible bone, 5% liver, 5% other secreting organ, 7% vegetables, 2% seeds or nuts, and 1% fruit. The plant portion replaces some of the muscle meat compared to PMR.
In both models, the organ percentages matter. Liver is essential because it provides fat-soluble vitamins, particularly vitamin A. But because vitamin A accumulates in the body, feeding more than 5% liver can cause problems over time. The remaining 5% organ should come from a different secreting organ like kidney or spleen, not more liver. Some dogs are sensitive to organ meat and do better with slightly less than the full 10%.
Getting the Bone Percentage Right
Bone content in a raw diet should land between 10% and 15% of the total food by weight for most adult dogs. This provides the calcium and phosphorus needed for healthy bones and teeth in a ratio the body can use efficiently. Too little bone can cause loose stools and mineral deficiencies. Too much leads to hard, chalky, dry stools and constipation.
Puppies may benefit from bone content closer to 15% to support skeletal growth, though excessive calcium can actually cause growth abnormalities in large breeds, so this needs careful attention. Senior dogs generally do better around 10%, since their digestive systems slow down with age and higher bone content is more likely to cause constipation.
These percentages refer to edible bone, not weight-bearing bones from large animals. Chicken necks, backs, and wings; duck necks and frames; and rabbit bones are all common edible bone sources that most dogs can crunch through safely.
How Often to Feed
Most adult dogs do well with two meals per day, though some thrive on just one. Split the total daily amount evenly across meals. Senior dogs also typically eat twice daily, but some prefer smaller meals spread over three feedings if they have trouble eating larger portions at once.
Puppies need to eat more frequently. Young puppies under four months may need four meals a day, gradually reducing to three and then two as they mature. Puppies also eat a higher percentage of their body weight than adults, often 5% to 8% depending on age and breed size, because they’re fueling rapid growth.
Adjusting for Activity Level
The 2–3% range assumes a moderately active pet dog. Working dogs, sporting dogs, and highly active breeds that get hours of exercise daily often need 3% to 4% or even more. A sled dog in training season or a herding dog working full days burns dramatically more calories than a companion dog getting two 30-minute walks.
On the other end, a dog that mostly lounges around the house, an older dog with arthritis, or a breed prone to easy weight gain may maintain ideal condition at 1.5% to 2%. The percentage is always a starting point. Your dog’s body tells you whether it’s right.
How to Tell If You’re Feeding the Right Amount
Weigh your dog every week or two when you first start raw feeding. Body condition is the real measure, though. Run your hands along your dog’s ribcage. You should feel each rib under a thin layer of covering, similar to how the back of your hand feels. If you have to press to find the ribs, reduce the daily amount by about 10%. If the ribs are visually prominent, increase by 10%.
Stool quality is another useful signal. Firm, small stools that are easy to pick up suggest good digestion and appropriate bone content. Very loose stools may mean too little bone or too much rich organ meat. White, crumbly stools mean too much bone. Adjust the ratios within your daily total rather than changing the overall amount when stool issues come up.
Give any change at least a week before adjusting again. Dogs’ digestive systems need time to adapt, and day-to-day variation is normal.
