Making a raw diet for your dog comes down to following a consistent ratio of muscle meat, bones, and organs, then adjusting portions based on your dog’s weight. Most homemade raw feeders use either the BARF model (Biologically Appropriate Raw Food) or the Prey Model Raw (PMR) approach, both built around the same core idea: replicate what a dog would eat in the wild using whole, unprocessed ingredients.
The BARF Ratio Breakdown
The most widely used framework splits your dog’s daily food into these proportions: 70% muscle meat, 10% raw edible bone, 5% liver, 5% other secreting organs, 7% vegetables, 2% seeds or nuts, and 1% fruit. This is a starting template, not a rigid formula. You don’t need to hit these numbers at every single meal. Instead, aim to balance them over the course of a week.
Muscle meat forms the bulk of the diet and can come from any animal protein: beef, chicken, turkey, pork, lamb, venison, or fish. Rotate between at least three different protein sources over time to cover a broader spectrum of nutrients. Dark meat cuts tend to be fattier, while leaner options like turkey breast or venison work better for dogs prone to weight gain.
Choosing the Right Bones
The 10% bone component is one of the trickiest parts to get right, and it’s where the most serious mistakes happen. Raw bones are the primary calcium source in this diet, and the calcium-to-phosphorus ratio should land around 1.2:1 to 1.4:1 for adult dogs. Too little bone means calcium deficiency. Too much can cause constipation and impacted stools.
Stick to soft, edible bones your dog can fully chew and swallow. Good options include chicken wings, chicken and duck necks, chicken and duck feet, chicken or duck frames (the ribs and back with breast meat removed), pork tails, lamb ribs, and whole quail or rabbit. These bones are soft enough to be digested safely.
Avoid weight-bearing bones from large animals like cows, deer, or oxen. These are extremely dense and cause tooth fractures and intestinal impaction. Turkey drumsticks and drumettes are also risky because they splinter when broken. Machine-cut bones from the grocery store, like bone-in pork chops or pre-cut neck bones, should be avoided too. The sharp edges from cutting make them dangerous, and they often lack the surrounding muscle meat that helps a dog chew and digest them safely.
Organs Are Not Optional
Organ meats are the nutritional powerhouse of a raw diet, and skipping them is the fastest way to create deficiencies. Liver specifically should make up 5% of the diet. It’s packed with vitamin A, copper, and B vitamins in concentrations no other ingredient can match. The remaining 5% comes from other secreting organs: kidney, spleen, brain, pancreas, thymus, or reproductive organs like testicles and ovaries.
The key word is “secreting.” Muscular organs like heart and gizzard don’t count toward this 5%. Heart is nutrient-dense and valuable, but it functions as muscle meat in the ratio. If you can’t find a wide variety of secreting organs at your local grocery store, ethnic markets, butcher shops, and online raw pet food suppliers typically carry them.
Calculating Daily Portions
Daily portions are based on a percentage of your dog’s body weight. An adult dog at a healthy weight should eat roughly 2% to 2.5% of their body weight per day. So a 50-pound dog would get 1 to 1.25 pounds of food daily, split across two meals. An active or underweight dog can go up to 3%. A senior, less active, or overweight dog may do better at 1.5% of their ideal weight.
For puppies, portion 2% to 3% of their expected adult weight, not their current weight. Puppies grow fast, and basing portions on current size leads to constant recalculation and potential underfeeding during growth spurts.
Where Homemade Raw Diets Fall Short
Research consistently finds nutritional imbalances in homemade raw diets, both home-prepared and some commercial versions. Calcium and phosphorus imbalances are the most common problem, along with specific vitamin deficiencies. A meat-heavy diet without enough bone or organ variety can trigger secondary nutritional hyperparathyroidism, a condition where the body pulls calcium from the bones to compensate for dietary shortfalls. Symptoms include muscle weakness, irritability, and skeletal demineralization, particularly in the pelvis and spine.
Certain raw ingredients also contain compounds that interfere with nutrient absorption. Raw eggs contain avidin, which destroys biotin. Raw fish contains thiaminases, which break down thiamine. Cooking eliminates these factors, so if you’re feeding eggs or fish raw, do so in moderation rather than as staples.
Many raw feeders add a few targeted supplements to fill gaps. Fish oil provides omega-3 fatty acids that most land-animal meats lack. Vitamin E often needs supplementation since it’s found primarily in plant oils and seeds. Zinc and manganese can also run low depending on your protein sources. Working with a veterinary nutritionist to run your recipe through a nutrient analysis, even once, can catch gaps before they become problems.
Special Considerations for Puppies
Puppies are far less forgiving of nutritional mistakes than adult dogs. Young dogs from weaning to about six months old cannot regulate how much calcium they absorb from their intestines. Whatever calcium goes in, their body takes up, which makes both deficiency and excess dangerous. Large and giant breed puppies are especially vulnerable to excess calcium. Oversupplementation (above 3% calcium on a dry-matter basis) worsens developmental bone conditions like osteochondrosis and slows normal skeletal remodeling.
Getting the bone content precisely right matters more for puppies than for any other life stage. If you’re formulating a raw diet for a growing puppy, especially a large breed, professional guidance on the specific recipe is worth the investment.
Transitioning From Kibble to Raw
A gradual switch over about 10 days works best. Start with 25% raw food mixed with 75% of the old diet for the first three days. Bump to 50/50 for days four through six, then 75% raw and 25% old food for days seven through nine. By day ten, you can feed fully raw. Dogs with sensitive stomachs may need a slower pace.
During the transition, expect some digestive adjustment. Loose stools, gas, bad breath, and occasional vomiting are common as the gut adapts. Mucus-covered stools can appear at any point, even well after the switch, and are generally not a concern. These symptoms typically resolve within a few days to a few weeks, though some dogs take longer.
Food Safety and Handling
Raw meat carries the same pathogen risks for your household that it does in your own cooking. Salmonella, Listeria, and E. coli are all possible contaminants in raw poultry, beef, and other proteins. Your dog’s digestive system handles these bacteria more robustly than yours, but you and your family are still exposed through handling.
Use a dedicated cutting board for raw dog food prep, separate from anything you use for your own meals. Store raw meat in sealed containers so juices don’t leak onto other foods. Keep your refrigerator at 40°F or below and your freezer at 0°F or below. Thaw frozen portions in the refrigerator, in cold water, or in the microwave, never on the counter, where bacteria multiply quickly on the portions that reach room temperature. Refrigerate prepared meals within two hours, or within one hour if the temperature is above 90°F. Wash your hands, bowls, and surfaces thoroughly after every feeding.
Putting a Week Together
A practical weekly meal plan for a 50-pound dog eating 2.5% of body weight (about 1.25 pounds per day, or roughly 8.75 pounds per week) would look something like this:
- Muscle meat (70%): About 6 pounds per week. Rotate between chicken thighs, beef chuck, turkey, and another protein of your choice.
- Raw edible bone (10%): About 14 ounces per week. Chicken wings, duck necks, or chicken frames spread across meals.
- Liver (5%): About 7 ounces per week. Beef or chicken liver, divided into daily portions.
- Other secreting organs (5%): About 7 ounces per week. Kidney, spleen, or a mix.
- Vegetables (7%): About 10 ounces per week. Lightly blended or steamed leafy greens, broccoli, or squash.
- Seeds/nuts (2%): About 3 ounces per week. Ground pumpkin seeds or sunflower seeds.
- Fruit (1%): About 1.5 ounces per week. Blueberries, apple slices, or banana.
Batch prep is the most realistic approach. Many raw feeders prepare one to two weeks of food at a time, portion it into daily containers, freeze everything, and thaw one day’s worth in the refrigerator overnight. This keeps handling time minimal and food safety manageable. Over time, you’ll develop a rhythm with sourcing, prepping, and rotating proteins that fits your schedule and your dog’s preferences.
