Raw Dog Food Calculator

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.
