Raw Dog Food Calculator

As a general rule, an adult dog should eat 2% to 3% of their ideal adult body weight in raw food daily. For a standard adult dog with moderate activity, 2.5% is the ideal starting baseline (for example, a 50 lb dog requires approximately 1.25 lbs or 20 oz of raw food per day). For senior dogs, couch companions, or dogs needing weight loss, feed 2.0% of their target weight. For highly active working or sporting dogs, increase to 3.0% to 3.5%. Growing puppies require significantly higher caloric intake: 8% to 10% of their current weight at 2–4 months, 6% to 8% at 4–6 months, and 4% to 6% at 6–12 months.

The BARF (Biologically Appropriate Raw Food) model follows a 70/10/10/10 ratio: 70% muscle meat, 10% raw meaty bone, 10% secreting organs (5% liver + 5% other secreting organ), and 10% vegetables, fruit, and seeds. BARF incorporates plant matter to mimic the stomach contents of wild prey and deliver essential antioxidants, bioflavonoids, and phytonutrients. The PMR (Prey Model Raw) diet follows an 80/10/10 ratio: 80% muscle meat, 10% raw meaty bone, and 10% secreting organs (5% liver + 5% other organ), excluding all plant ingredients to recreate whole wild prey.

Raw Meaty Bones (RMBs) are soft, pliable, non-weight-bearing bones surrounded by at least 50% meat that can be completely chewed, crushed, and digested by a dog's acidic stomach. Examples include chicken necks, chicken wings, chicken frames, duck necks, turkey necks, lamb ribs, and pork ribs. Recreational bones, such as large beef femur marrow bones or knuckles, are dense weight-bearing bones meant only for gnawing and should never be consumed entirely because they cause tooth fractures (slab fractures) and intestinal impaction. NEVER feed cooked bones of any kind, as cooking alters bone collagen, causing them to splinter into sharp shards.

Organs are the most nutrient-dense components of a carnivore's diet. Liver is mandatory at 5% because it provides unmatched levels of preformed Vitamin A, iron, copper, and essential B vitamins (folate, B12). However, feeding more than 5% liver can lead to hypervitaminosis A and loose stool. The second 5% MUST come from a secreting organ—such as kidney, spleen, pancreas, thymus, or brain—which provides unique trace minerals like selenium, zinc, manganese, and essential fatty acids. Muscular organs like heart, gizzard, lung, and tongue count as muscle meat, not secreting organs.

A gradual 14-day transition is safest for your dog's digestive tract. Days 1–3: Feed 25% raw (single protein, boneless muscle meat like skinless turkey or lean beef) and 75% previous diet in separate meals. Days 4–7: Feed 50% raw and 50% previous diet, introducing soft raw meaty bones like chicken necks. Days 8–10: Feed 75% raw and 25% previous diet, slowly introducing small amounts of liver. Days 11–14: Feed 100% raw with full BARF or PMR balance, adding second secreting organs and vegetables. Add pure pumpkin puree or raw goat milk/kefir to support gut flora during transition.

Yes, puppies can thrive on raw food from weaning (3 to 4 weeks old), but their calcium, phosphorus, and caloric requirements are far more demanding than adults. Puppies must be fed based on their CURRENT weight using an age-tiered percentage: 8%–10% of body weight (2–4 months), 6%–8% (4–6 months), and 4%–6% (6–12 months), divided into 3 to 4 meals daily. Raw meaty bone content must be precisely maintained at 12% to 15% (for large breed puppies) to ensure the mandatory 1.2:1 calcium-to-phosphorus ratio for healthy skeletal development.

The most frequent deficiencies in poorly balanced DIY raw diets are: 1) Omega-3 EPA/DHA (must supplement with wild sardines, canned mackerel in water, or wild salmon oil); 2) Vitamin E (depleted when feeding fats/oils; supplement with natural d-alpha-tocopherol); 3) Iodine (must add kelp powder or ocean fish); 4) Manganese (found in green-lipped mussels, hemp seeds, and leafy greens); 5) Zinc (supplement with oysters or zinc picolinate); and 6) Vitamin D (canned sardines or egg yolks). A rotating variety of at least 3 distinct animal proteins per month prevents trace deficiencies.

Healthy canines have an evolutionary digestive tract designed to handle bacteria: an ultra-acidic gastric pH of 1.0 to 2.0 (comparable to battery acid) that kills pathogenic bacteria, along with a short, rapid gastrointestinal transit time (4 to 8 hours) that prevents colonization. For humans handling raw meat, standard sanitary kitchen hygiene is essential: wash hands with warm soapy water for 20 seconds, sanitize cutting boards and stainless steel dog bowls with hot soapy water or a diluted bleach solution, and thaw meat in the refrigerator rather than on countertops.

To prep monthly batches: 1) Purchase bulk muscle meat, bones, and organs from local butchers or co-ops; 2) Weigh ingredients on a digital kitchen scale according to the calculator's 30-day batch amounts; 3) Portion daily meals into airtight freezer-safe silicone containers or BPA-free vacuum-sealed bags; 4) Freeze all meat at -4°F (-20°C) for at least 3 weeks prior to feeding to eliminate potential parasites; 5) Thaw 2 to 3 days of food in the refrigerator at a time; and 6) Discard any uneaten raw meat left in your dog's bowl after 20 to 30 minutes.

On a raw diet, stool volume decreases by 50% to 70% and becomes firmer with minimal odor because the dog digests and absorbs virtually all natural nutrients without filler grains or starches. If your dog produces dry, white, crumbly, or chalky stool after 24 hours, it indicates excess calcium (too high a bone percentage). Reduce the raw meaty bone portion and increase boneless muscle meat. Conversely, loose, dark, or watery stools suggest too much rich organ meat (liver) or unadapted fat; decrease organs temporarily and add pureed pumpkin.

While some dogs tolerate mixed bowls, veterinary nutritionists recommend feeding raw food and dry kibble in separate meals (for example, kibble for breakfast and raw food for dinner). Kibble is rich in high-glycemic starches that require a less acidic gastric environment (pH 3.5–4.5) and slower digestive transit (10–12 hours), whereas raw meat digests rapidly in an ultra-acidic pH (1.5–2.0). Feeding them separately prevents digestive fermentation, gas, and stomach upset.

Safe vegetables and fruits include spinach, kale, zucchini, broccoli, cauliflower, carrots, celery, green beans, pumpkin, blueberries, blackberries, and cranberries. Because dogs cannot break down the cellulose plant cell walls, all vegetables MUST be finely pureed in a blender, steamed, or fermented before feeding to ensure nutrient absorption. STRICTLY AVOID toxic plants: onions, garlic, chives, leeks, grapes, raisins, currants, green unripened tomatoes, raw potatoes, and wild mushrooms.
