Frequently Asked Questions
Most adult dogs thrive on 2–3% of their ideal body weight in raw food daily. A 50-pound dog, for example, would eat roughly 1 to 1.5 pounds of raw food per day. Puppies need considerably more — between 5% and 8% — because of their rapid growth rate. Senior dogs with lower metabolic demands typically do well at 1.5–2%. Activity level also plays a significant role: a working Border Collie needs more than a couch-loving Basset Hound.
BARF stands for Biologically Appropriate Raw Food and includes roughly 70% muscle meat, 10% bone, 10% vegetables and fruit, and 10% organ meat (split between liver and other secreting organs). The Prey Model eliminates all plant matter and allocates 80% muscle meat, 10% bone, 5% liver, and 5% other organs. BARF proponents value the fiber and phytonutrients from produce, while Prey Model advocates argue dogs are obligate carnivores that do not need plant-based foods.
Raw feeding can be appropriate for puppies when properly balanced, but it requires careful attention to calcium-phosphorus ratios for healthy bone development. Puppies need 5–8% of their body weight daily, split across three to four meals until about six months of age, then reduced to two meals. Consult a veterinarian or board-certified veterinary nutritionist before starting a puppy on raw food to ensure all micronutrient needs are met during this critical growth window.
Activity level directly affects your dog's daily caloric needs. A highly active working dog, such as a sled dog or herding breed that works several hours a day, may burn two to three times the calories of a sedentary companion dog. Our calculator adjusts the base feeding percentage upward for active dogs and downward for low-activity dogs to prevent underfeeding or overfeeding. These multipliers are based on the National Research Council's energy requirement guidelines for canines.
Raw meaty bones — such as chicken backs, turkey necks, duck frames, and lamb ribs — are generally considered safe because they are soft enough for dogs to crush and digest. Never feed cooked bones, as cooking makes them brittle and prone to splintering, which can cause intestinal perforation. Weight-bearing bones from large animals (beef femurs, marrow bones) are too dense for most dogs and can crack teeth. Always supervise your dog during bone meals and choose bone sizes appropriate for your dog's jaw strength.
Most veterinary raw-feeding guides recommend a gradual transition over 7–14 days. Start by replacing 25% of kibble with raw food for the first three days, then increase to 50% for the next three days, then 75%, and finally 100% raw. Some dogs with sensitive stomachs may need a slower transition. During the switch, you may notice temporary changes in stool consistency — this is normal as the gut microbiome adjusts to the new diet.
Liver is uniquely nutrient-dense — it contains extremely high concentrations of vitamin A, copper, and B vitamins compared to other organs. Feeding too much liver can cause vitamin A toxicity (hypervitaminosis A), so raw feeding guidelines cap liver at 5% of the total diet. The remaining 5% organ allocation goes to other secreting organs like kidney, spleen, pancreas, or brain, which provide a different micronutrient profile. This separation ensures balanced nutrition without risking toxicity.
For adult dogs, splitting the daily amount into two meals (morning and evening) helps maintain stable blood sugar levels and reduces the risk of bloat, especially in deep-chested breeds like Great Danes and German Shepherds. Puppies under six months should eat three to four smaller meals per day. Senior dogs also benefit from two meals to ease digestive workload. You can rotate protein sources across meals — for example, chicken-based in the morning and a beef-based mix in the evening.
A properly balanced raw diet following BARF or Prey Model ratios with variety in protein sources generally covers most nutritional bases. However, many raw feeders supplement with fish oil (omega-3 fatty acids), vitamin E, and occasionally kelp for iodine. Dogs that do not eat enough raw bone may need a calcium supplement. Consult your veterinarian to assess whether your specific dog needs additional supplementation based on blood work and overall health status.
This calculator is specifically designed for dogs. Cats are obligate carnivores with different nutritional requirements — they need higher protein, taurine supplementation, and zero plant matter. Feline raw diets follow different ratios (typically 84% muscle meat, 6% bone, 5% liver, 5% other organ). We recommend using a species-specific calculator for cats or other animals to ensure the correct nutrient balance for their unique physiology.
What Is a Raw Dog Food Calculator?
A raw dog food calculator takes your dog's weight, age, and activity level and tells you exactly how much raw food to feed each day — broken down by meat, bone, liver, organ, and vegetables. It removes the guesswork from raw feeding so you can build a diet that's genuinely balanced, not just roughly right.
This tool supports both the BARF diet (Biologically Appropriate Raw Food) and the Prey Model raw feeding approach. BARF includes vegetables and fruit for added fiber and phytonutrients. Prey Model sticks strictly to the 80/10/10 muscle-bone-organ split that mirrors what a wild canid would eat. Neither is wrong — the best diet is the one your dog thrives on and you can maintain consistently.
Raw feeding isn't complicated once you understand the ratios. Whether you're a first-timer switching from kibble or a seasoned raw feeder recalibrating after your dog's annual checkup, this raw dog food calculator gives you an accurate daily target in seconds.

Raw Dog Food Guide: What Every Feeder Should Know
Switching to raw is one of the most impactful changes you can make for your dog's long-term health. But it works best when you understand the basics before you start. Here's what matters most.
Choosing Between BARF and Prey Model
The BARF diet, developed by Australian veterinarian Dr. Ian Billinghurst in the early 1990s, includes 10% vegetables and fruit. The logic: dogs are omnivores that scavenge plant matter in the wild. Prey Model adherents disagree — they argue dogs are obligate meat-eaters and plant matter adds little value. In practice, the difference in outcomes is small for most dogs. If your dog has digestive issues with vegetables, go Prey Model. If they do fine with greens, BARF gives you more variety and some useful phytonutrients.
Raw Feeding Safety: Handling and Storage
Handle raw meat the same way you would for your own cooking — wash hands, keep surfaces clean, and don't cross-contaminate. Freeze protein sources for 2–3 weeks before feeding, especially pork and wild-caught fish, to eliminate most parasites. The American Veterinary Medical Association (AVMA) recommends against raw diets for households with immunocompromised people, infants, or elderly individuals due to bacterial risk — something to factor into your decision.
Transitioning Your Dog to Raw Food
Don't mix raw and kibble in the same meal — they digest at different rates and can cause stomach upset. Instead, do a hard switch: stop kibble, wait 12 hours, then introduce raw. Most adult dogs transition without issue. Puppies and seniors may need 3–5 days of just chicken and bone before you add variety. Loose stools in the first week are normal as gut bacteria adjust. Firm, chalky white stools usually mean too much bone — back off the RMBs by 20–30% and see if it resolves. For a detailed step-by-step plan, read our guide to transitioning your dog to raw food.
Supplementing a Raw Diet
A well-built raw diet rotating across 3–4 protein sources is largely self-sufficient. But a few supplements can add insurance: fish oil (omega-3 balance), vitamin E (balances the extra fat-soluble vitamins from organ meat), and kelp or a whole-food iodine source (thyroid support). The Association of American Feed Control Officials (AAFCO) sets minimum nutrient guidelines that a properly constructed raw diet can meet — but only if the organ ratios and protein rotation are right. Use our raw dog food calculator to make sure your ratios are on point before adding supplements.
Who Should Use This Calculator?
This tool was built for anyone feeding or considering a raw diet for their dog. In practice, that means:
- First-time raw feeders who don't know where to start with portions and want a reliable baseline before experimenting.
- Experienced BARF practitioners recalculating after a weight gain, loss, or seasonal activity change.
- Prey Model feeders who want a quick breakdown without doing the math manually every time they rotate proteins.
- Rescue volunteers and shelter staff managing multiple dogs with different weights and life stages.
- Breeders adjusting puppy portions week by week as litters grow — puppies can double their weight in the first few weeks of life.
- Holistic vets and canine nutritionists who want a fast reference tool to share with clients during consultations.
If you're managing more than one dog, run the calculator for each individually — a 15 lb senior terrier and a 90 lb active working dog have very different nutritional demands even on the same feeding model.
