Can Dogs Eat Gizzards? Raw vs Cooked and Safe Portions
By Dr. Zubair Khalid, DVM, MS, PhD ·
Can dogs eat chicken gizzards? Yes, they can. Gizzards are lean muscle meat, and a plain, fully cooked gizzard is a safe occasional treat for most healthy dogs. The real questions are whether you serve them raw and how much you feed, because too much organ-style meat can upset a balanced diet.

Quick Answer
- Cooked, plain chicken gizzards are safe for most dogs in small amounts.
- Raw gizzards carry a real risk of Salmonella, Campylobacter, and other bacteria that can sicken your dog and your household.
- Treat gizzards as a topper or training reward, not a meal replacement.
- Never feed gizzards cooked with onion, garlic, salt, xylitol, or heavy oil.
- Cut cooked gizzards into bite-size pieces to lower choking risk, especially for small dogs.
Are Chicken Gizzards Safe for Dogs?
A plain, cooked chicken gizzard is safe for most healthy dogs. It is muscle meat, not a secreting organ like liver or kidney, so it does not carry the same vitamin A overload concern that liver does. The gizzard is the muscular part of the chicken's digestive tract, and it is dense, chewy, and high in protein.
The verdict changes when you add seasoning, when you serve it raw, or when gizzards make up too much of your dog's daily calories. A gizzard by itself is not toxic. The preparation and the portion decide whether it helps or hurts.
If you are already exploring raw or lightly cooked animal proteins, the same bacterial and handling rules apply across the board. Our guide on Can Dogs Eat Raw Chicken? Salmonella and Campylobacter Risk covers those risks in more detail.
Can Dogs Eat Gizzards Raw?
Raw chicken gizzards are not recommended for most households. Raw poultry is a well-known source of Salmonella and Campylobacter, and these bacteria can infect your dog and spread to people through bowls, counters, hands, and saliva. The risk is not only to the dog. Young children, older adults, and anyone immunocompromised in the home faces a higher chance of serious illness from cross-contamination.
Some owners choose raw diets for perceived health benefits. Research on owner attitudes shows that people who feed raw meat-based diets often rank their own nutrition knowledge higher than their veterinarian's, even though the evidence for health advantages is limited [1]. A large survey of UK owners found that raw feeders and non-raw feeders differ in how they choose and handle food, which suggests handling practices, not just the food itself, shape the risk [2].
There is also a digestibility angle. Processing conditions, including the temperature and duration of heating, affect how well a dog food is digested [3]. A separate study comparing the same ingredient formulas made by retort, mildly cooked, and raw methods found that processing method influences amino acid digestibility and energy value [4]. That does not prove raw is better or worse for your individual dog, but it does mean "raw equals more natural equals healthier" is an oversimplification.
If you still want to feed raw gizzards, talk to your veterinarian first, use strict hygiene, freeze meat properly, and keep raw meat away from areas where you prepare human food. For many owners, cooking is the simpler and safer choice.
Can Dogs Eat Gizzards Cooked?
Yes, cooked gizzards are the safer option. Heat kills the bacteria that make raw poultry risky. Boil, bake, or simmer gizzards with no seasoning, then cool them before serving. Plain cooked gizzards are a lean protein treat that most dogs enjoy.
Keep the cooking method simple. Do not fry gizzards in oil, and do not add salt, garlic, onion, or powdered seasoning blends. Garlic and onion are toxic to dogs, and xylitol, a sweetener found in some sauces and sugar-free products, is dangerous even in small amounts. A boiled gizzard is fine. A gizzard from a seasoned stew is not.
Overcooking makes gizzards rubbery and harder to chew. That raises the choking risk for small dogs and for dogs who gulp food. Cut cooked gizzards into small, thin pieces, and watch your dog eat the first few to see how they handle the texture.
Can Dogs Eat Gizzards and Hearts?
Yes, dogs can eat both gizzards and hearts, and both are muscle meat. Chicken heart is nutrient-dense and higher in certain vitamins and minerals than gizzard, but it is still muscle tissue, not a secreting organ. That means you can feed small amounts of each without the vitamin A concerns that come with liver.
The catch is total volume. If you pile gizzards, hearts, and liver into the bowl, you are feeding a lot of animal protein and organ meat on top of a complete diet. That can unbalance the meal and cause loose stool. Treat gizzards and hearts as a small part of the day's calories, not a second dinner.
A practical approach is to pick one muscle-meat treat per day. If you feed gizzard today, skip the heart. If you want to feed both, keep each portion tiny and count them together against your dog's treat allowance.
Nutritional Value and Real Benefits
Chicken gizzards are high in protein and low in fat compared with many other meats. They provide B vitamins, iron, zinc, and other minerals. For a dog who needs to lose weight or who has a sensitive stomach, a small piece of plain cooked gizzard can be a satisfying, low-calorie reward.
The benefit is modest. Gizzards are a treat, not a therapeutic food. They do not replace a complete and balanced diet, and they do not treat any medical condition. If your dog has kidney disease, liver disease, pancreatitis, or a food allergy, ask your veterinarian before adding any new protein.
One large study of dogs fed different diet types found that home-cooked diets were associated with higher odds of owner-reported gastrointestinal, renal, and hepatic disease compared with extruded diets [5]. That finding does not single out gizzards, but it is a reminder that homemade additions to the bowl can shift the nutritional balance in ways owners do not always see.
Risks of Feeding Gizzards
Bacterial contamination
Raw gizzards can carry Salmonella and Campylobacter. These bacteria cause vomiting, diarrhea, fever, and lethargy in dogs, and they can spread to humans in the home. Cooking kills them.
Choking and blockages
Gizzards are dense and chewy. Large pieces can lodge in the throat or esophagus, especially in small breeds, flat-faced dogs, and fast eaters. Always cut them small.
Digestive upset
Too much rich protein or a sudden new food can cause vomiting or diarrhea. Introduce any new treat in a single small piece and wait a day before offering more.
Toxic additives
Gizzards are often sold marinated, breaded, or in seasoned broth. Onion, garlic, salt, xylitol, and some preservatives are dangerous. Read labels or cook from raw plain meat yourself.
Unbalanced nutrition
Gizzards are not a complete diet. If they replace too much of your dog's regular food, your dog can miss out on calcium, vitamins, and other nutrients.
How to Offer Gizzards Safely
Start with one small piece of plain cooked gizzard. Watch for vomiting, diarrhea, or itching over the next 24 hours. If your dog tolerates it, you can offer a few small pieces a few times a week.
| Form | Safe? | Notes |
|---|---|---|
| Plain boiled or baked gizzard | Yes | Cool fully, cut into small pieces |
| Raw gizzard | No, not recommended | Bacterial risk to dog and household |
| Fried or breaded gizzard | No | Oil, breading, and seasoning can upset the gut |
| Gizzard in seasoned broth or stew | No | Onion, garlic, salt, and xylitol risk |
| Gizzard with heart | Yes, in small amounts | Count both toward the treat limit |
| Gizzard as a full meal | No | Not complete or balanced |
Weekly portion guide
Treats should stay a small share of your dog's daily calories. A common guideline is to keep treats under about 10 percent of daily calories, with the rest coming from a complete and balanced diet. Your veterinarian can help you set an exact number based on your dog's weight, body condition, and health.
As a rough starting point for a healthy adult dog:
- Small dogs (under 20 lb): 1 to 2 small pieces, 2 to 3 times per week
- Medium dogs (20 to 50 lb): 2 to 4 small pieces, 2 to 3 times per week
- Large dogs (over 50 lb): 4 to 6 small pieces, 2 to 3 times per week
These are general ranges, not medical doses. Adjust based on your dog's size, activity, and current diet. If your dog is overweight or on a prescription diet, ask your veterinarian before adding gizzards at all.
Parts and preparations to avoid
Avoid gizzards that are raw, breaded, fried, marinated, smoked with added salt, or packed in broth with onion or garlic. Avoid any product sweetened with xylitol. Avoid giving whole gizzards to dogs who gulp food.
What to Do If Your Dog Ate Too Much or a Dangerous Form
If your dog ate a large amount of plain cooked gizzard, expect some stomach upset. Withhold extra treats, keep fresh water available, and watch for vomiting or diarrhea. Most mild cases settle within a day.
If your dog ate raw gizzards, watch closely for vomiting, diarrhea, fever, or lethargy over the next few days. Call your veterinarian if symptoms appear, because bacterial infections may need treatment.
If your dog ate gizzards cooked with onion, garlic, xylitol, or a large amount of salt, contact a veterinarian or an animal poison control service right away. Do not wait for symptoms. Bring the packaging or a photo of the ingredient list if you have it.
If your dog is choking, gagging, drooling heavily, or struggling to breathe, this is an emergency. Go to the nearest veterinary emergency hospital immediately.
Safer Alternatives
If you want a lean protein treat and gizzards are not a good fit, there are other options. Plain cooked chicken breast, plain cooked turkey, and small pieces of cooked egg are common choices. Our article on Can Dogs Eat Eggs? Raw Salmonella vs Scrambled explains how to prepare eggs safely.
For plant-based treats, some dogs do well with small pieces of plain cooked vegetables. Our guide on Can Dogs Eat Asparagus? Raw vs Cooked Digestibility covers one option, and Can Dogs Eat Mulberries? Safe Portions Guide covers a fruit treat. Always introduce one new food at a time.
Limitations and When to Contact a Veterinarian
This article gives general guidance. Your dog's age, weight, health conditions, medications, and current diet all change what is safe. Individual cases need a veterinarian who knows your dog.
Contact your veterinarian the same day if your dog ate raw gizzards and then vomited, had diarrhea, or seemed tired. Call right away if your dog ate gizzards cooked with onion, garlic, xylitol, or a lot of salt.
Go to an emergency clinic now if your dog is choking, having trouble breathing, collapsing, having repeated vomiting, or showing severe abdominal pain. Do not wait to see if it passes.
Schedule a routine visit if you want to add gizzards or any new food to your dog's diet long term, especially if your dog has kidney, liver, heart, or gastrointestinal disease.
Frequently Asked Questions
Can dogs eat gizzards every day?
A small piece of plain cooked gizzard most days is fine for many healthy dogs, as long as treats stay a small share of daily calories. Feeding large amounts daily can unbalance the diet and cause loose stool. Ask your veterinarian for a portion that fits your dog's weight and health.
Are chicken gizzards better for dogs than chicken breast?
Not really. Both are lean muscle meat with good protein. Gizzards are chewier and a bit higher in some minerals, but chicken breast is easier to cut into safe small pieces. Pick whichever your dog tolerates and you can prepare plainly.
Can puppies eat gizzards?
Puppies can eat small pieces of plain cooked gizzard once they are eating solid food, but their nutritional needs are high and their stomachs are sensitive. Keep portions tiny and avoid raw gizzards entirely. Check with your veterinarian before adding any new treat to a puppy's diet.
Do gizzards count as organ meat for dogs?
No. Gizzards are muscle meat, not secreting organ meat. Liver, kidney, and spleen are the organs that carry vitamin and mineral overload concerns. Gizzards and hearts are grouped with muscle meats instead.
What happens if my dog eats a whole bag of raw gizzards?
A large raw gizzard meal raises the risk of bacterial infection and serious stomach upset. Watch for vomiting, diarrhea, fever, and lethargy, and call your veterinarian if any appear. If your dog is very small, very young, or immunocompromised, call your veterinarian right away.
