Preparing raw meat for dogs involves portioning muscle meat, edible bone, and organ meat into balanced ratios, then handling and storing everything safely to avoid bacterial contamination. The most widely followed framework calls for roughly 75–80% muscle meat, 10% raw edible bone, 5% liver, and 5% other secreting organs. Getting those proportions right, choosing the correct cuts, and keeping your kitchen sanitary are the core skills you need.
The Basic Ratio to Follow
Two main templates guide raw feeders. The Prey Model Raw (PMR) diet aims to mimic a whole prey animal: 75–80% muscle meat, 10% raw edible bone, 5% liver, 5% other secreting organs (kidney, spleen, pancreas, or brain), and up to 5% animal-based fiber like green tripe. The BARF model is similar but adds plant matter: 70% muscle meat, 10% raw edible bone, 5% liver, 5% other organs, 7% vegetables, 2% seeds or nuts, and 1% fruit.
Either template works as a starting point. The important thing is that liver and at least one other secreting organ are both present. Liver supplies a concentrated dose of vitamin A and copper, while organs like kidney and spleen fill in iron and B vitamins that muscle meat alone can’t provide. Treating “organs” as interchangeable with muscle meat is the single most common mistake new raw feeders make.
Choosing and Portioning Muscle Meat
Muscle meat is the bulk of every meal, so variety matters here more than anywhere else. Rotate between chicken thighs, turkey breast, beef chuck, pork shoulder, lamb, and fish like sardines or mackerel over the course of a week or two. Each protein source has a different amino acid and fatty acid profile, so rotating reduces the chance of a chronic gap in any one nutrient.
For an average pet dog that gets a daily walk and some playtime, aim for roughly 10% fat content across the diet on an as-fed basis. That means you don’t need to trim every bit of fat from a chicken thigh, but you also shouldn’t be feeding mostly fatty trimmings or skin. If you’re using very lean cuts like turkey breast or venison, adding a small amount of fat (about 5% of the meal’s weight) from a fattier source keeps energy levels adequate. Fat contains double the calories of protein gram for gram, so a little goes a long way.
Selecting Safe Edible Bones
The 10% bone component serves a specific purpose: it supplies calcium. The ideal calcium-to-phosphorus ratio for an adult dog is about 1.2:1 by weight, and raw edible bone naturally hits close to that mark when paired with muscle meat and organs. Some dogs do well with bone content bumped up to 12–15%, which you’ll notice if their stools are firm but not chalky white.
Edible bones are soft enough for a dog to chew and fully consume. For small to medium dogs, chicken necks, chicken backs, and duck necks work well. Larger dogs can handle turkey necks, chicken frames, or rabbit. The key distinction is between edible bones and recreational or weight-bearing bones (like beef marrow bones or femurs), which are dense enough to crack teeth and should not be part of the meal ratio.
Never cook bones before feeding. Cooking changes the structure, making them brittle and prone to splintering into sharp fragments. Raw bones flex and crush, which is what makes them digestible. Always match the bone size to your dog. If your dog can fit the entire piece in its mouth at once, it’s a choking hazard. Go larger.
Handling Organ Meats
Liver and other secreting organs are nutrient-dense but easy to overfeed. At 5% each, the actual portions are small. For a 50-pound dog eating about 2% of body weight daily (roughly 16 ounces of food), that’s less than an ounce of liver and less than an ounce of another organ per day. Many people find it easier to portion organs into weekly batches rather than trying to weigh tiny amounts daily.
Beef liver, chicken liver, and lamb liver are all widely available. For the “other organ” category, beef kidney is the easiest to source, but spleen, pancreas (sweetbreads), and brain all count. Heart does not count as an organ in raw feeding terms. It’s a working muscle and belongs in the muscle meat category, though it’s an excellent one to include because of its taurine content.
Freezing to Reduce Parasite Risk
Freezing meat before feeding is a standard precaution. The CDC recommends freezing pork less than 6 inches thick at -15°C (5°F) for 20 days to kill parasites like the worms that cause trichinosis. Most home freezers run around -18°C (0°F), which meets that threshold. For beef and poultry, a minimum of two to three weeks in a home freezer is a reasonable precaution, though parasites in these meats are less common.
One caveat: freezing does not reliably kill all parasites in wild game. Some species that infect venison, wild boar, and bear are freeze-resistant. If you’re sourcing wild game, this is worth knowing.
Freezing also does not eliminate bacteria like Salmonella or E. coli. It pauses their growth but doesn’t kill them. That’s why kitchen hygiene during prep is essential for your safety, not just your dog’s.
Batch Prep and Storage
Most raw feeders prepare meals in bulk, portion them into daily servings, and freeze. Here’s a practical workflow:
- Weigh your components. Calculate your dog’s daily intake (typically 2–3% of body weight for adults), then apply the ratio. For a week’s worth of food, multiply each component by seven.
- Cut and portion. Dice muscle meat into chunks appropriate for your dog’s size. Separate bone-in pieces. Slice organ meats into small portions.
- Pack into containers or bags. Silicone molds, reusable containers, or freezer-safe zip bags all work. Each container should hold one day’s food (or one meal if you feed twice daily).
- Freeze immediately. Label with the date and protein type.
When it’s time to feed, move the next day’s container from the freezer to the refrigerator to thaw overnight. Once fully thawed, use the food within 24 to 48 hours. Don’t refreeze thawed raw meat, and don’t leave it sitting at room temperature for more than 15–20 minutes in the bowl.
Nutrients That May Be Missing
Even a well-constructed raw diet can fall short on certain minerals. Research published in The Canadian Veterinary Journal found that homemade raw diets were commonly deficient in potassium, magnesium, and zinc. These gaps don’t cause obvious problems in the first few weeks, but over months they can affect coat quality, immune function, and muscle health.
Zinc is the trickiest one because meat contains some, but often not enough. Red meat is the richest source, so beef and lamb rotations help. Whole sardines and eggs also contribute. Many raw feeders add a small amount of kelp powder for iodine and trace minerals, or use a raw-diet-specific vitamin and mineral premix to cover the gaps. If you feed the BARF model, including pumpkin seeds (in the seeds/nuts portion) adds both zinc and manganese.
Rotating proteins broadly, including fish once or twice a week for omega-3 fatty acids, and feeding whole eggs with the shell a few times a week for extra calcium and trace minerals will get you closer to complete nutrition than sticking with a single protein source.
Keeping Your Kitchen Safe
Raw meat carries bacteria that can make you and your family sick, even if your dog handles it fine. Treat raw dog food prep exactly like you’d treat handling raw chicken for your own dinner.
Use a dedicated cutting board for raw dog food. Wash your hands with soap and warm water for at least 20 seconds after handling any raw meat. Clean all surfaces, knives, and bowls with hot soapy water immediately after use. To disinfect, the CDC recommends a bleach solution of 2 ounces (a quarter cup) of household bleach per gallon of water. Soak bowls and tools in this solution for at least 10 minutes, then rinse.
Avoid using the kitchen sink for cleaning your dog’s bowls if possible, since splashing can transfer bacteria to nearby food prep areas. If the kitchen sink is your only option, scrub and disinfect the entire sink and surrounding counter immediately afterward. A bathroom sink, laundry sink, or bathtub is a safer alternative. Remove any personal items from the area before you start.
Your dog’s food bowl should be washed after every single meal. Stainless steel or ceramic bowls are easier to fully sanitize than plastic, which can develop tiny scratches that harbor bacteria.
