Hazelnuts offer plenty of health benefits for people. They are full of vitamin E, healthy fats, protein, fiber, and antioxidants that help your heart, fight inflammation, and give you steady energy. They are a great snack for us, but what about dogs? Can dogs eat hazelnuts?
The short answer is that hazelnuts are not poisonous to dogs, but they are not a good choice for them either. Before you give your dog any hazelnuts or foods with hazelnuts, make sure you know the facts to keep your pet safe.
It can be tempting to share snacks with your dog, but hazelnuts can cause problems you might not expect. One study found that vet visits for nut-related issues have gone up by 35% as more people give their pets human snacks. To help keep your dog safe, here are 8 important safety tips every owner should know. It is worth asking: can dogs eat hazelnuts?
What Are Hazelnuts?
Hazelnuts are small, round tree nuts with a hard brown shell and a sweet, mild flavor. They contain healthy fats, vitamins, and minerals that are beneficial for people. However, foods that are safe for humans are not always safe for dogs.
Can Dogs Eat Hazelnuts? The Quick Answer
Hazelnuts are not toxic to dogs, but they are still risky. Although hazelnuts do not contain toxins that will poison dogs, they can cause several health problems and are not recommended as treats.
Are Hazelnuts Safe for Dogs?
Choking is a primary concern, especially for small dogs. The size and shape of hazelnuts increase the risk of them becoming lodged in a dog’s throat. If swallowed whole, the hard shells are difficult to digest and may cause blockages in the digestive tract.
Digestive problems are also common. Dogs do not process nuts well, which can result in vomiting, diarrhea, or abdominal pain. The high fat content in hazelnuts can further upset their digestive system.
Pancreatitis is the most serious risk. This is a painful inflammation of the pancreas that can be life-threatening and requires prompt veterinary care. The high fat content in hazelnuts can trigger pancreatitis, particularly if a dog eats several nuts.
4 Major Risks of Feeding Hazelnuts to Dogs
You might want to give your dog a hazelnut as a treat, but it’s better not to. Hazelnuts have some nutrients, but they can actually be harmful to dogs.
Here are four major risks to avoid giving hazelnuts to your dog, so you can help keep them safe and healthy.
1.Choking Hazard and Intestinal Blockage
Hazelnuts are risky for small dogs because of their size and hard shells. They can get stuck in your dog’s throat and cause choking. The shells do not break down in the stomach and can block the digestive tract. Small dogs are at higher risk because their airways are smaller.
Digestive Tract Obstruction Risks
When dogs swallow hazelnuts whole or in large pieces, they risk developing intestinal blockages. These indigestible shells can accumulate in the digestive tract, creating dangerous obstructions that may require surgical removal. The rough, sharp edges can also scratch or irritate your dog’s mouth, esophagus, and intestines, leading to inflammation and bleeding.
Emergency Signs to Watch For
If your dog eats hazelnuts, watch for these warning signs:
- Persistent vomiting or retching
- Difficulty breathing or excessive panting
- Blue or pale gums indicate oxygen deprivation
- Pawing at the mouth or face
- Loss of appetite or refusal to eat
- Lethargy or abnormal behavior
- Difficulty defecating or abdominal pain
Call your vet right away if you notice any of these symptoms. Quick action can make a big difference.
2.High Fat Content and Pancreatitis Risk
Hazelnuts are high in fat, containing about 60.7 grams per 100 grams. Because dogs have a harder time processing fatty foods than humans, even small amounts of hazelnuts can cause problems for them.
Eating high-fat foods like hazelnuts can put dogs at risk for pancreatitis, which is inflammation of the pancreas. Signs to watch for include:
- Repeated vomiting and diarrhea
- Loss of appetite and lethargy
- Abdominal pain and bloating
- Fever and dehydration
If your dog shows any of these symptoms after eating hazelnuts, contact your veterinarian as soon as possible. Pancreatitis needs prompt treatment.
3.Mold Contamination and Toxicity
Raw hazelnuts can sometimes be contaminated with mold during harvesting and storage. These molds may produce toxic compounds called aflatoxins and mycotoxins, which are harmful to dogs.
Raw hazelnuts frequently contain aflatoxins, particularly aflatoxin B1, which is classified as a group 1 human carcinogen. Studies show that up to 12% of raw hazelnut samples contain aflatoxin levels ranging from 0.09 to 11.3 μg/kg. These toxic compounds are produced by the Aspergillus fungus during the growing and storage processes.
Hazelnuts contain juglone, a natural compound that helps protect the plant. In dogs, juglone can cause gastrointestinal upset, even if the nuts are shelled.
If your dog consumes contaminated hazelnuts, watch for these warning signs:
- Vomiting and diarrhea within 1-2 hours
- Muscle tremors and uncontrollable shaking
- Seizures and convulsions
- Excessive panting and increased heart rate
- Difficulty breathing
- Loss of appetite and lethargy
Raw hazelnuts are more likely to develop mold during harvesting, drying, and storage than processed nuts. Mold is not always visible, so contaminated nuts may look normal but still contain toxins. Even small amounts can be harmful to dogs.
4.Allergic Reactions in Sensitive Dogs
Dogs can develop food allergies, and some foods may cause allergic reactions. If your dog has eaten something new, look for these signs:
- Persistent itching and scratching across the body, face, paws, or belly
- Facial or body swelling, particularly around the eyes, mouth, ears, or throat
- Digestive distress, including vomiting or diarrhea that comes and goes
- Difficulty breathing or excessive panting, especially if the mouth or throat appears swollen
- Red, inflamed skin or hives appearing as bumps or welts
Dogs can react differently to allergens. Some may have mild skin irritation, while others may have more severe symptoms. Food allergies usually develop gradually. Common triggers include proteins such as beef, chicken, and dairy.
8 Amazing Safety Tips for Hazelnuts and Dogs
Dogs are often curious about new snacks, but hazelnuts are not the best choice. Even though they are not toxic, there are some important safety issues to keep in mind before sharing them with your dog.
Tip 1: Remove All Shells Completely
Hazelnut shells are dangerous for dogs. They can cause choking, especially in small breeds, and may even lead to serious blockages if swallowed. The shells can also contain toxins that upset your dog’s stomach and cause symptoms like vomiting or diarrhea.
Proper Preparation Techniques
If you do give hazelnuts, make sure all shells are removed. Even small pieces of shell can be risky. Only use plain, unsalted, roasted hazelnuts with nothing added.
- Cut hazelnuts into very small pieces to help prevent choking.
- Only offer one or two small pieces at most.
- Watch your dog for any signs of stomach trouble.
- If you notice any symptoms, call your vet right away.
The safest option is to skip hazelnuts and stick with dog-friendly treats like plain peanuts.
Tip 2:Choose Only Plain, Roasted Hazelnuts.
If you decide to give hazelnuts, only use plain, roasted ones. These are the safest for your dog.
Never give dogs hazelnuts that are:
- Salted or seasoned
- Chocolate-coated
- Flavored with additives
Flavored hazelnuts can have dangerous ingredients like chocolate or xylitol, which are very harmful to dogs. Salt and seasonings can also upset their stomach.
Tip 3: Limit Portion Sizes Strictly
If you share hazelnuts with your dog, be careful with the amount you give.
The amount depends on your dog’s size:
- Small breeds: Maximum 2 hazelnuts per week
- Medium breeds: No more than 3 hazelnuts per week
- Large breeds: Maximum 4 hazelnuts per week
Cut hazelnuts into small pieces to help prevent choking, especially if your dog tends to eat quickly.
Hazelnuts should only be an occasional treat and should not make up more than a small part of your dog’s diet. Giving them once a week is better than offering them every day.
Tip 4: Monitor for Immediate Reactions
Watch your dog closely after they eat hazelnuts. Problems can show up quickly or take a day or two to appear, so keep an eye out for any changes.
Monitor for these warning signs:
- Digestive issues: Vomiting, diarrhea, nausea, or loss of appetite
- Allergic reactions: Itching, swelling, hives, or breathing difficulties
- Choking hazards: Pawing at the mouth, gagging, or drooling excessively
- Blockage symptoms: Bloating, whining when touched, or constipation
Tip 5 – Avoid If Your Dog Has Health Conditions
Do not give hazelnuts to dogs with pancreatitis, obesity, or kidney issues. The fat in hazelnuts can make these problems worse.
If your dog has a sensitive stomach, it is best to avoid hazelnuts. They can cause diarrhea, stomach pain, or vomiting.
Consult your veterinarian before giving hazelnuts to a dog with pre-existing health conditions. If your dog with a medical condition accidentally eats hazelnuts, call your vet for advice right away.
- Flavored hazelnuts contain toxic chocolate and xylitol.
- These ingredients cause kidney failure and dangerous blood sugar drops.
- Salt upsets digestive systems in dogs.
Tip 6: Never Give Raw Hazelnuts
Raw hazelnuts are risky for dogs and should be avoided.
Raw hazelnuts can have mold, especially from fungi that make aflatoxins. These toxins can cause serious problems for dogs, like tremors, tiredness, heavy breathing, or even worse. Raw hazelnuts can also upset your dog’s stomach and cause vomiting or diarrhea.
If you do give hazelnuts, only use plain, roasted ones. Roasting helps get rid of mold that can be found in raw nuts. Never give your dog hazelnuts that are:
- Salted or seasoned
- Chocolate-coated
- Flavored with additives
Storing hazelnuts the right way helps prevent mold. Keep them in a cool, dry place to avoid problems.
Tip 7 – Keep Mixed Nuts Away Completely
Mixed nuts are not safe for dogs. They often include nuts like walnuts or macadamia nuts, which are toxic. Even if hazelnuts are okay, mixed nuts are too risky.
Mixed nuts can also have a lot of salt, which is bad for your dog’s kidneys. Sometimes they are mixed with chocolate, xylitol, or other things that are very dangerous for dogs.
Instead of mixed nuts, offer:
- Plain carrots or apple slices
- Small pieces of cooked chicken
- Dog-specific treats without nuts
- Air-popped popcorn (unsalted)
These options are safer and avoid the risks of choking or toxic ingredients.
Tip 8 – Know When to Call Your Vet
Knowing the signs of an emergency and how to react can make a big difference for your dog.
Call your vet immediately if your dog shows:
- Difficulty breathing or choking
- Uncontrolled bleeding for more than 5 minutes
- Repeated vomiting or vomiting blood
- Sudden collapse or seizures
- Hard, swollen abdomen
- Inability to urinate or defecate
Before you get to the vet:
- Stay calm and assess the situation safely.
- Control bleeding with clean gauze for at least 3 minutes.
- Keep your dog warm and quiet.
- Approach slowly – injured dogs may bite.
Symptoms of Hazelnut Toxicity in Dogs
If your dog eats hazelnuts, you might notice these signs within a few hours.
- Vomiting and diarrhea
- Lethargy and weakness
- Abdominal pain and drooling

Most symptoms show up within an hour of your dog eating hazelnuts. Sometimes, mild stomach issues can get worse as time goes on. If the nuts have mold, your dog could get very sick very quickly.
If your dog has trouble breathing, has a seizure, or collapses, call your vet right away. If you only see mild vomiting or diarrhea, keep a close watch and reach out to your vet for advice.
Safer Treats Instead of Hazelnuts
Hazelnuts can be a choking hazard, but there are plenty of safer treats your dog can enjoy.
Dog-Safe Nuts (in Small Amounts)
- Peanuts (technically legumes) – unsalted and shelled varieties only
- Cashews – roasted and plain are best, since they’re softer
- Chestnuts – stick to cooked, unseasoned American chestnuts
- Always take off the shells to help prevent choking.
Other Healthy Treat Ideas
- Carrots – a crunchy snack that can help keep your dog’s teeth clean
- Sweet potato chips – bake them until they’re crispy for a fun texture
- Apple slices – just remember to take out the seeds, and your dog will love the crunch
- Cooked eggs – a good source of protein if your dog can’t have nuts
Easy Homemade Dog Treats
- Peanut Butter Banana Bites – mash up bananas with peanut butter (make sure it’s xylitol-free)
- Carrot Crunchies – mix grated carrots with whole wheat flour
- Pop them in the freezer until they’re firm for the best texture.
Store-Bought Dog Treats
- Freeze-dried meat treats – look for single-ingredient options like chicken or beef
- Training treats – soft and chewy ones are best, since they’re less likely to cause choking
- Always check the label to make sure there is no xylitol.
Conclusion
Hazelnuts are not poisonous to dogs, but they just are not worth the risk. The dangers are much greater than any possible health benefits. Hazelnuts can be a choking hazard, especially for small dogs. They are also high in fat, which can upset your dog’s stomach or even cause pancreatitis. If the nuts have mold, they can be especially dangerous.
Instead of hazelnuts, try safer treats like plain peanut butter (without xylitol), small carrot pieces, or dog treats made for your dog’s size. These choices let your dog enjoy a special snack without worry.
If your dog eats hazelnuts by accident, watch them closely for any signs of trouble like vomiting, diarrhea, or trouble breathing. If you are not sure what to do, call your vet right away. They know your dog’s health history and can help you decide what is best. The safest treats are the ones that are both tasty and right for your dog’s needs.
