Can Dogs Eat Chicken Hearts and Gizzards Raw? (The Complete Safety Guide)

You pull a pack of chicken hearts from the grocery store. Your dog is watching you with that look. You’re wondering — is this actually okay to give them raw, or are you about to make a big mistake?
I’m Thomas Cutter, and I’ve spent years researching canine nutrition for fodogs-20. The short answer is yes — raw chicken hearts and gizzards are a legitimate part of a raw-fed dog’s diet. But there are rules that matter. Skip them and you can hurt your dog. Follow them and you’re giving your dog one of the most nutritious foods they can eat.
Here’s everything you need to know before you feed.

Are Raw Chicken Hearts and Gizzards Actually Good for Dogs?

Yes — raw chicken hearts and gizzards are genuinely nutritious for dogs and are a staple in raw feeding diets worldwide. These organs provide a concentrated source of protein, vitamins, and minerals that many commercial kibbles can’t match. They aren’t just safe — they’re beneficial when fed correctly.
Dogs evolved eating whole prey. That diet naturally included organs, muscle meat, and bone. Chicken hearts and gizzards fit that biological blueprint almost perfectly. Vets who support raw feeding regularly include them as foundational proteins.

What’s Actually Inside Chicken Hearts?

The chicken heart is technically classified as muscle meat, not a secreting organ. That matters because it doesn’t count toward the strict organ limit the way liver does.
Here’s what a 100g serving of raw chicken heart delivers for your dog:

This table shows the key nutrients in raw chicken heart per 100g and why each one benefits your dog directly.

Taurine is particularly important — a deficiency has been linked to dilated cardiomyopathy (DCM) in dogs, making hearts a genuinely therapeutic food for at-risk breeds.

What’s Inside Chicken Gizzards?

Gizzards are a digestive organ — the muscular part of the stomach that grinds food. They’re dense, chewy, and loaded with protein. Dogs love the texture, and the nutritional profile supports lean muscle and immune function.
Gizzards are lower in fat than hearts. They’re a good fit for dogs that need high protein with controlled caloric intake. They’re also rich in glucosamine, which supports joint health — especially useful in larger or older dogs.

What Are the Real Risks of Feeding Raw Chicken Organs to Dogs?

The risks are real — but they’re manageable. You need to understand them clearly before you feed anything raw. Skipping this section is how people make their dogs sick.
There are 3 main risk categories: bacterial contamination, dietary imbalance, and individual dog sensitivity. Each one has a clear fix.

Bacterial Contamination — Salmonella and Campylobacter

Raw poultry can carry Salmonella, Campylobacter, and Listeria. A healthy adult dog’s gut is significantly more acidic than a human’s. That acidity is a natural defense — it kills most pathogens before they cause harm.
But here’s the thing: dogs can still shed bacteria in their stool even if they show no symptoms. That’s a human health risk, not just a dog risk. If you have young children, elderly family members, or immunocompromised people in your home, handle raw chicken organs the same way you handle raw chicken for human cooking.

Dietary Imbalance — The 10% Rule

Organs are nutrient-dense. That’s their strength and their risk. Too much organ meat — especially liver — causes vitamin A toxicity. Gizzards and hearts are safer in this regard, but the principle still applies.
The 10% rule is the industry-standard guideline used by raw feeders globally: organs should make up no more than 10% of your dog’s total daily food intake. For a 30-pound dog eating 450g of food per day, that’s 45g of organ meat — about the size of 4-5 chicken hearts.

Individual Sensitivity — Some Dogs React Differently

Some dogs — especially those that have only ever eaten kibble — experience loose stools or digestive upset when switching to raw food. This isn’t a sign that raw is wrong. It’s a transition response.
The fix is simple: start with cooked gizzards and hearts. Cook them lightly, feed a small amount for 1 week, then slowly introduce the raw version. This gives your dog’s gut bacteria time to adjust.

How Do You Feed Raw Chicken Hearts and Gizzards to Your Dog Safely?

Safe raw feeding comes down to sourcing, handling, and portioning. Get these 3 things right and you’ll never have a problem.

How Much Is the Right Amount by Dog Size?

The 10% rule works in practice like this. Calculate your dog’s total daily food intake, then take 10% of that number. That’s the maximum amount of organ meat per day.

This table shows recommended daily organ meat portions by dog weight — use it as your starting reference before consulting your vet.

These are daily maximums — you don’t need to feed organs every day. 2–3 times per week within these limits is the standard raw feeding recommendation.

Should You Feed Hearts and Gizzards Raw or Cooked?

Both are safe. The choice depends on your dog’s health status, your household situation, and your comfort level. Raw preserves more nutrients. Cooked eliminates bacterial risk entirely.
The raw feeding community strongly prefers raw — heat destroys some taurine, CoQ10, and B vitamins. A 5-minute light steam reduces nutrient loss significantly compared to full cooking. If you’re new to raw feeding or your dog has a sensitive stomach, start cooked and transition slowly.

What Most People Get Wrong About Feeding Dogs Raw Organs

Misinformation travels fast in dog nutrition communities. Here are the 3 biggest misconceptions that lead people to either avoid a beneficial food entirely or feed it dangerously wrong.
Misconception 1: “Chicken hearts are organs and count toward the strict organ limit.”
This one causes real harm. Many raw feeders under-feed hearts because they classify them as organs alongside liver. Hearts are cardiac muscle, not secreting organ tissue. They don’t accumulate vitamin A the way liver does. You can feed them more freely than true secreting organs — up to 5% of the diet on their own, not just as part of the full 10% organ quota.
Misconception 2: “If my dog has been eating raw for years, I don’t need to worry about bacteria.”
A raw-adapted gut handles bacteria more efficiently — but it doesn’t eliminate risk entirely. Cross-contamination at preparation time is still a real concern. Always wash your hands, surfaces, and bowls after handling raw poultry organs. Your dog is fine. You and your family need the same precautions as handling raw chicken in your kitchen.
Misconception 3: “Gizzards are tough and hard for dogs to digest.”
Gizzards feel tough to us. Dogs don’t chew the way we do — they tear and swallow in chunks. A healthy dog’s stomach acid (pH 1–2) breaks down gizzard tissue efficiently. The “hard to digest” concern applies to cooked bone, not raw soft tissue like gizzards. No preparation or grinding is needed for most dogs.

Can Puppies Eat Raw Chicken Hearts and Gizzards?

Puppies can eat cooked chicken hearts and gizzards safely — but raw is a different story. A puppy’s immune system is still developing. Their gut flora is less robust than an adult dog’s. The risk of Salmonella causing serious illness is meaningfully higher in puppies under 6 months.
The safe approach for puppies: lightly steam or boil hearts and gizzards until fully cooked. Feed small amounts — start with just 1 small heart or half a gizzard. Watch for loose stool or vomiting over the next 24 hours.
At 12 months, once a puppy has a mature immune system, you can begin a gradual raw transition under veterinary guidance. Some raw feeding vets do support raw organ feeding from 8 weeks onward — but this should only happen with a vet’s explicit sign-off and close monitoring.

What Signs Tell You the Organs Aren’t Agreeing With Your Dog?

Most dogs tolerate hearts and gizzards well from the start. But watch for these responses in the first 48 hours after introducing them.

Conclusion

Raw chicken hearts and gizzards are safe, nutritious, and a genuinely excellent addition to a dog’s diet when handled correctly. The benefits — taurine, CoQ10, iron, B12, and protein — are hard to match with any supplement or commercial food. The risks are real but fully manageable with proper sourcing, freezing, handling, and portioning.
Keep organs at or under 10% of total daily intake. Source human-grade. Freeze before first use. Start small and watch your dog’s response. For puppies, seniors, or dogs with immune conditions, cook first and consult your vet.
Do this right now: Take 2 minutes to calculate 10% of your dog’s daily food intake using the table above. That’s your organ meat limit. Write it down and keep it visible in your kitchen.
