Can Dogs Eat Chicken Gizzards and Hearts? A Pet Parent’s Guide to Safe, Nutritious Treats

It’s a familiar scene: You’re prepping dinner, and there, beside you, is your dog—tail wagging, nose twitching, those big, soulful eyes locked on the cutting board. Tonight, you’re handling chicken giblets: rubbery gizzards and plump, red hearts. You pause, wondering: Can dogs eat chicken gizzards and hearts? Are these humble organ meats a healthy snack for your pup, or should they stay off the menu?

If you’ve ever asked this question, you’re not alone. Pet parents often turn to human foods as treats, and organ meats like gizzards and hearts are a common curiosity.

Can Dogs Eat Chicken Gizzards and Hearts? The Short Answer

Yes, dogs can eat chicken gizzards and hearts—in moderation. When prepared safely (plain, unseasoned, and properly cooked or handled raw), these organ meats are nutrient-dense treats that can support your dog’s health. They’re packed with protein, vitamins, and minerals that complement a balanced diet.

But “moderation” is key. Overfeeding, improper preparation, or serving them with harmful additives (like garlic or salt) can lead to health issues. Let’s unpack the benefits and risks to help you make the best choice for your pup.

Nutritional Benefits of Chicken Gizzards and Hearts for Dogs

Chicken gizzards and hearts are often overlooked, but they’re nutritional powerhouses. Here’s why they might make a great occasional treat:

1. High-Quality Protein for Muscle Health

Both gizzards and hearts are rich in lean protein, which is essential for building and repairing muscle, supporting healthy skin and coat, and fueling your dog’s energy. A 3-ounce serving of cooked chicken heart contains about 17 grams of protein, while gizzards offer around 16 grams—making them an excellent low-fat protein source for active dogs or those watching their weight.

2. B Vitamins for Energy and Brain Function

Chicken hearts and gizzards are loaded with B vitamins, including:

  • Vitamin B12: Critical for nerve function, red blood cell production, and energy metabolism. Deficiencies can lead to fatigue or neurological issues.
  • Riboflavin (B2): Supports skin health and converts food into energy.
  • Niacin (B3): Aids in digestion and maintains healthy cholesterol levels.

These vitamins work together to keep your dog’s brain sharp and body energized—perfect for playful pups or senior dogs needing a vitality boost.

3. Iron, Zinc, and Potassium for Overall Wellness

  • Iron: Found in both organs, iron helps transport oxygen in the blood. Low iron can cause anemia, especially in growing puppies or pregnant dogs.
  • Zinc: Supports immune function, wound healing, and healthy digestion. A zinc-rich diet may even help dogs with skin allergies.
  • Potassium: Regulates heart rate, muscle function, and fluid balance. Hearts, in particular, are a natural source of this mineral—fitting, given their role in canine heart health!

4. Taurine: A Heart-Healthy Amino Acid

Chicken hearts are an excellent source of taurine, an amino acid vital for dogs’ cardiovascular health. Taurine helps regulate heart rhythm, supports eye function, and aids in bile acid production. While most dogs produce taurine naturally, some breeds (like Cocker Spaniels, Boxers, and Bulldogs) are prone to deficiencies, which can lead to dilated cardiomyopathy (DCM). Adding small amounts of heart to their diet can help bridge this gap.

5. Fiber (From Gizzards) for Digestion

Gizzards are muscular organs (chickens use them to grind food), so they’re tough and fibrous. When cooked and chopped, this fiber can act as a gentle digestive aid, helping move food through your dog’s gut and supporting regular bowel movements. Just be mindful—too much fiber can cause loose stools, so moderation is key!

Potential Risks to Watch For

While chicken gizzards and hearts are nutritious, they’re not without risks. Here’s what to avoid:

1. Choking and Blockage Hazards

Gizzards are dense and chewy, and hearts can be slippery—both pose a choking risk, especially for small dogs or those who gulp food. Raw gizzards may be softer, but cooked ones can become tough and harder to chew. Always chop gizzards and hearts into bite-sized pieces (no larger than a dime for toy breeds!) to reduce this risk.

2. Bacterial Contamination (Raw vs. Cooked)

Raw chicken—including gizzards and hearts—can harbor harmful bacteria like Salmonella or E. coli, which can sicken both dogs and humans. While some dogs have strong stomachs, puppies, seniors, or dogs with weakened immune systems are more vulnerable.

If you choose to feed raw:

  • Source high-quality, human-grade meat.
  • Freeze it for 48 hours first to kill parasites (like Toxoplasma).
  • Thaw safely in the fridge, not on the counter.
  • Wash hands, bowls, and surfaces thoroughly after handling.

Many vets recommend cooking giblets to eliminate bacteria. Boiling or baking (without oil) is best—avoid frying, which adds unnecessary fat.

3. Seasonings and Additives: A Hidden Danger

Never feed your dog gizzards or hearts that are seasoned, marinated, or cooked with:

  • Salt: Excess sodium can cause dehydration, kidney damage, or salt poisoning.
  • Garlic/Onion: These are toxic to dogs, even in small amounts, and can destroy red blood cells (leading to anemia).
  • Spices: Paprika, pepper, or other seasonings may irritate your dog’s stomach.

Stick to plain, unseasoned giblets—your pup won’t miss the flavor, and their body will thank you.

4. Upset Stomach from Overfeeding

Introduce new foods slowly! Even healthy treats can cause diarrhea, vomiting, or gas if your dog eats too much too soon. Start with a tiny piece (e.g., half a chopped heart for a small dog) and monitor for 24 hours. If all goes well, gradually increase the amount.

5. Weight Gain (If Overindulged)

While gizzards and hearts are low in fat, they’re not calorie-free. A 3-ounce serving of cooked chicken heart has about 130 calories—equivalent to a small dog biscuit. If you’re already giving treats, adding giblets could push your dog over their daily calorie limit, leading to obesity over time.

How Much Chicken Gizzards and Hearts Can Dogs Eat?

The golden rule for treats: They should make up no more than 10% of your dog’s daily calories. This ensures their regular food (which is balanced for all nutrients) remains the star of their diet.

Here’s a rough guideline based on your dog’s weight:

Dog SizeWeight (lbs)Recommended Amount (Cooked, Chopped)Frequency
Toy (e.g., Chihuahua)5–10 lbs1–2 small pieces (≈1 tsp)2–3x/week
Small (e.g., Beagle)15–30 lbs2–3 pieces (≈1 tbsp)2–3x/week
Medium (e.g., Cocker Spaniel)30–60 lbs3–4 pieces (≈2 tbsp)1–2x/week
Large (e.g., Labrador)60–100+ lbs4–5 pieces (≈¼ cup)1x/week

Note: Adjust based on your dog’s activity level, age, and health. Puppies, seniors, and dogs with conditions like diabetes need personalized advice—ask your vet!

Healthier Alternatives (When to Choose Something Else)

Chicken gizzards and hearts are great, but they’re not the only option. If you’re looking for variety, try these nutrient-dense alternatives:

1. Turkey Hearts/Gizzards

Similar to chicken, but often leaner. Turkey is a common protein in hypoallergenic dog foods, so it’s a good choice for dogs with chicken sensitivities.

2. Lean Chicken Breast

Skinless, boneless chicken breast is low in fat and high in protein—perfect for dogs on a diet. It’s also easier to find and less chewy than gizzards, making it safer for small breeds.

3. Salmon (Cooked, No Bones)

Rich in omega-3 fatty acids, which support joint health, skin, and coat. Just avoid raw salmon (risk of parasites) and ensure it’s unseasoned.

4. Green Beans or Carrots

Low-calorie, crunchy, and packed with fiber and vitamins. Great for dogs watching their weight—frozen green beans make a refreshing summer treat!

5. Commercial Organ Meat Treats

For convenience, look for freeze-dried chicken heart or gizzard treats (e.g., from brands like Stella & Chewy’s or Orijen). These are portion-controlled and free of additives.

FAQ: Your Most Pressing Questions Answered

Q: Can puppies eat chicken gizzards and hearts?

A: Yes, but in tiny amounts! Puppies have sensitive tummies, so start with ¼–½ a chopped piece (cooked) and monitor for digestion issues. Avoid raw to reduce bacterial risk—puppies’ immune systems are still developing.

Q: Is raw chicken gizzards better than cooked for dogs?

A: It depends on your comfort level. Raw diets (BARF) claim benefits like better dental health, but the AVMA warns of bacterial risks to both pets and humans. Cooked giblets are safer for most households—just avoid overcooking, which can deplete nutrients.

Q: Can dogs eat chicken gizzards every day?

A: No. Even with benefits, daily servings can lead to nutrient imbalances (e.g., too much iron) or weight gain. Stick to 1–3x/week at most.

Q: Are chicken hearts good for dogs with kidney disease?

A: Maybe, but ask your vet first. Hearts are moderate in phosphorus (a mineral kidney patients need to limit). Your vet can help adjust portions based on your dog’s specific needs.

Q: My dog ate seasoned chicken gizzards—what should I do?

A: If the seasoning included garlic, onion, or large amounts of salt, call your vet immediately. These can be toxic. For mild spices (e.g., a little pepper), monitor for vomiting/diarrhea and offer water to dilute.

Conclusion: Moderation is Key

Chicken gizzards and hearts can be a delicious, nutritious addition to your dog’s treat rotation—when served safely and in moderation. They’re packed with protein, vitamins, and minerals that support everything from muscle health to heart function. But remember: They’re treats, not meals. Always keep portions small, avoid seasoning, and consult your vet if you have concerns (especially for puppies, seniors, or dogs with health conditions).

At the end of the day, the best treat is one that keeps your pup happy and healthy. So next time you’re prepping chicken, share a tiny, chopped piece—your dog’s tail (and their body) will thank you!
