A dog can look at a piece of liver like it is the greatest thing to ever happen in your kitchen. That enthusiasm is useful, but it can also lead owners to feed too much of a good thing. The best organ meats for dogs deliver concentrated nutrition that plain muscle meat cannot provide, yet they belong in a balanced feeding plan, not as an unlimited treat bowl.

For raw-fed dogs, organs help fill nutritional gaps naturally. They supply vitamins, minerals, essential fatty acids, and amino acids in forms dogs are built to use. The key is variety, appropriate portions, and a clear understanding that not every item sold as an “organ” plays the same role in a raw diet.

What counts as organ meat in a dog’s diet?

Raw-feeding conversations often use the word “organ” in two different ways. In the broad kitchen sense, liver, heart, kidney, lung, spleen, pancreas, and brain are all organs. In diet formulation, however, heart is usually counted as muscle meat because of its structure, while liver and other secreting organs are handled separately because they are so nutrient-dense.

That distinction matters. A dog can eat a fair amount of heart as part of the meat portion of a meal. Liver, on the other hand, can cause loose stool when introduced too quickly and can push vitamin A intake too high when fed in excess over time.

For many prey-model raw diets, organs make up about 10% of the overall ration, with roughly half of that organ portion coming from liver and the other half coming from another secreting organ. A complete, professionally formulated raw meal may use a different recipe to meet nutritional targets. Do not add large amounts of extra organs on top of a complete diet unless you have adjusted the full recipe accordingly.

The 7 best organ meats for dogs

1. Liver: the foundational secreting organ

Liver is usually the first answer when people ask about the best organ meats for dogs. Beef, chicken, turkey, lamb, and pork liver all provide highly concentrated vitamin A, B vitamins, iron, copper, and folate. It is an efficient way to add real-food nutrition, and most dogs find it extremely palatable.

Its strength is also its limit. Liver should be a consistent but modest part of the diet, not a daily free-for-all. For a dog new to raw feeding, begin with a tiny amount and build up slowly. Soft stool is a common sign that the serving increased faster than the dog’s system could handle.

2. Kidney: a valuable second secreting organ

Kidney is an excellent partner to liver in a balanced raw rotation. It contributes protein, selenium, B vitamins, and minerals while offering a nutrient profile that is different from liver. Beef and lamb kidney are commonly available, but poultry kidney can work as well.

Some kidney has a stronger smell, especially after thawing. That is normal, although it should still smell fresh rather than sour or rotten. If your dog is hesitant, mince it into a meal or offer a smaller amount alongside a familiar protein. Dogs with diagnosed kidney disease need individualized veterinary guidance rather than a standard raw-feeding ratio.

3. Spleen: nutrient-dense and often overlooked

Spleen is a useful secreting organ that can stand in for part of the non-liver organ portion. It is especially rich in iron and can be darker and bloodier in appearance than other organs. That can make it look intimidating to people, but it is a natural food source for dogs.

Because spleen is rich, introduce it gradually just as you would liver or kidney. It is a practical option for owners who want more rotation and may not always be able to source pancreas or other specialty organs.

4. Pancreas: a useful rotation option

Pancreas is another secreting organ that can provide variety within a properly balanced diet. It contains protein and naturally occurring digestive enzymes. Some raw feeders seek it out because of those enzymes, but it should not be treated as a cure for digestive problems or pancreatic disease.

Pancreas can be harder to find and may cost more than liver or kidney. When available from a trusted supplier, it is a good rotation choice. Its role is nutritional variety, not a reason to abandon a diet that is already balanced and working for your dog.

5. Heart: technically muscle meat, still worth feeding

Heart does not replace liver or kidney in raw-diet ratios, but it earns a place on this list because it is one of the most useful nutrient-dense animal foods for dogs. It is a lean, protein-rich muscle that naturally contains taurine, iron, zinc, and B vitamins.

Beef heart is a favorite for many raw feeders because it is often affordable, easy to portion, and accepted by picky dogs. Feed it as part of the muscle-meat portion of the meal. If you are building meals yourself, do not count heart toward your secreting-organ percentage.

6. Lung: lean, light, and great for training treats

Lung is another organ that is generally treated more like muscle meat in a raw diet. It is lean and airy, and its texture makes it particularly useful for dehydrated training treats. Fresh lung can also be included in a meal rotation for dogs that do well with it.

It is not as nutritionally concentrated as liver or kidney, so it is not the piece that makes a diet complete. Think of it as a useful protein variety and a high-value reward option, not as a substitute for the organs that supply key micronutrients.

7. Brain: rich, but a specialty food

Brain is rich in fat and contains omega-3 fatty acids, cholesterol, and other nutrients. It can add useful variety, but it is not necessary for every dog or every raw diet. Its richness may be too much for dogs with sensitive digestion or a history of pancreatitis.

Source brain carefully and use it in small portions. It is best treated as an occasional rotational food, especially for dogs already eating a complete diet with appropriate fatty-acid balance.

How much organ meat should you feed?

The answer depends on what the rest of the bowl contains. If you feed a complete and balanced commercial raw food, extra liver, kidney, or spleen should be occasional and small. A few bite-sized pieces can be a great topper or training reward, but regular large additions can unbalance the diet.

If you formulate meals at home, the common starting framework is 5% liver and 5% other secreting organ as part of the total food amount. That framework is not a substitute for full nutritional formulation. Puppies, pregnant or nursing dogs, seniors, dogs with medical conditions, and dogs eating a limited-protein diet all have needs that may call for a more tailored plan.

Start with less than the final target amount. Small dogs may only need a pea-sized introduction, while larger dogs can begin with a modest bite. Watch stool quality, appetite, itching, and overall comfort as you make changes. Loose stool often means you need to reduce the amount and slow down.

Handling matters as much as the ingredient

Organ meat is perishable. Buy from suppliers that maintain cold-chain handling and can clearly tell you what species the ingredient came from. Keep organs frozen until you are ready to use them, thaw portions in the refrigerator, and wash hands, bowls, and food-contact surfaces after prep.

Portioning makes the process easier. Freeze organs in small meal-sized packages or mix them into a properly balanced batch before freezing. That prevents the common mistake of grabbing a large chunk of liver because it is convenient, then accidentally feeding several days’ worth at once.

At Chew Dat Foods, we believe raw feeding should be practical as well as nutrient-focused. Real ingredients matter, but so does getting the portions right consistently. A dog thrives on a balanced pattern of feeding, not on one nutrient-packed ingredient doing all the work.

When you add organs with purpose, rotate what is available, and pay attention to your dog’s response, these foods can bring real variety and value to the bowl without turning mealtime into a guessing game.
