How Much Raw Food to Feed a Dog: BARF Portions by Body Weight

Raw feeders size portions differently from kibble feeders: instead of calories and cups, the convention is a percentage of body weight per day, split across muscle meat, bone and organ. The math is simple, but the details (life stage, activity, weight goals and the component split) decide whether the plan is sensible. Here is the standard method, with a worked table. Before you commit to raw at all, read is raw dog food safe? for the risk picture.

The 2 to 3 percent rule

A healthy adult dog is typically fed 2 to 3 percent of ideal body weight per day in raw food. "Ideal" matters: if your dog is overweight, use the weight they should be, not the weight they are. A practical default is 2.5 percent, then tune from there:

• 2 percent: couch-potato adults, seniors, easy keepers, weight loss.
• 2.5 percent: the typical adult starting point.
• 3 percent: lean, energetic adults or dogs that need to gain.
• 3 percent and up: genuinely hard-working dogs (sport, herding, sledding), scaled to workload.

Puppies are the big exception. A growing puppy commonly eats 5 to 10 percent of current body weight per day (highest when young, tapering as they approach adult size), split into three or four meals. An alternative is 2 to 3 percent of the expected adult weight. Either way, growth is where home-prepared raw goes wrong most often, so a puppy raw diet belongs in the hands of a board-certified veterinary nutritionist, not a forum recipe.

The 80/10/10 split

Within the daily total, the standard BARF framing is 80 percent muscle meat, 10 percent raw meaty bone and 10 percent organ, with about half of the organ share (5 percent of the total) as liver. Muscle meat carries protein and calories, bone supplies calcium and phosphorus, and organs carry the vitamin load. Treat the ratio as a skeleton, not a guarantee: a diet can hit 80/10/10 exactly and still be short on nutrients like vitamin E, zinc or omega-3s, which is why formulated recipes and periodic vet checks matter.

Worked portions by dog weight

At the 2.5 percent starting point, the daily portion and its 80/10/10 split look like this. Feed it across two meals for most adults.

Percentages are a shortcut for the same thing every diet is really targeting: calories. If you want a cross-check, run your dog through our food portion calculator (or the RER/MER feeding guide) and compare the calorie target against what your raw menu actually delivers. A raw portion that is way off the calorie math is a sign the percentage needs adjusting.

Transitioning to raw

• Switch gradually over 7 to 10 days, replacing a growing share of the old food, or do a clean switch after a single fasted meal if your dog has a sturdy stomach. Loose stool for a few days is common; ongoing digestive upset is not.
• Start with one simple protein (chicken or turkey is typical) before rotating in others.
• Weigh portions with a kitchen scale. At these gram sizes, eyeballing drifts fast.
• Handle it like raw meat for people: dedicated surfaces, wash hands and bowls, keep it frozen until use.

When to involve your vet

Always for puppies, pregnant or nursing dogs, seniors and any dog with a medical condition. For healthy adults, get the plan sanity-checked at the start and recheck body condition at each visit: you should feel ribs easily without pressing and see a waist from above. If your dog drifts from that, adjust the daily percentage by about half a point and reassess in two to three weeks. And if you are still weighing raw against premium cooked options, see what human-grade actually means.
