Can Dogs Have Hazelnuts

When it comes to sharing snacks with our furry friends, it’s natural to wonder which foods are safe and which could spell trouble. Hazelnuts, with their rich, nutty flavor, are a favorite for many humans, but what about dogs? Can dogs have hazelnuts without risking their health, or is it a treat best kept off their menu? 

In this guide, we’ll explore everything you need to know about hazelnuts for dogs, covering safety, nutrition, benefits, risks, symptoms of illness, and the right way to feed nuts to your pup. For a safer, balanced approach, a tailored meal plan from Petly ensures your pet gets the nutrients they need without the risks of human snacks.

Are Hazelnuts Safe for Dogs

The short answer is yes, but with caution. Hazelnuts are not inherently toxic to dogs like macadamia nuts, but that doesn’t mean they’re completely safe. While a single, plain hazelnut is unlikely to cause harm in a healthy dog, they can be a choking hazard, especially for smaller breeds. Their hard texture makes them difficult to chew and digest, which could lead to intestinal blockage if swallowed whole.

Another safety concern is that flavored or salted hazelnuts, common in human snacks, can cause health issues in dogs. Excess salt can lead to dehydration or even sodium ion poisoning, while chocolate- or sugar-coated hazelnuts are outright dangerous for pets.

So, while dogs can have hazelnuts in tiny amounts, they should be plain, unsalted, and offered in moderation.

Nutritional Value of Hazelnuts for Dogs

Hazelnuts pack a nutritional punch for humans, and some of those nutrients can also benefit dogs, provided they are given in small quantities. They contain:

• Healthy fats – support skin and coat health.

• Protein – helps with muscle maintenance.

• Vitamin E – an antioxidant that supports immune function.

• Magnesium & calcium – important for bone health.

• B vitamins – aid in energy production and metabolism.

However, while these nutrients sound great, hazelnuts are also high in fat and calories. Dogs that consume too many calories can quickly gain weight, which may increase the risk of obesity-related issues like pancreatitis. A personalized meal plan can help maintain optimal nutrition without risky snacks.

In short, nutritionally, hazelnuts offer some benefits, but dogs don’t need them, and there are safer ways to provide these nutrients through dog-friendly foods.

Potential Benefits of Feeding Hazelnuts to Dogs

While hazelnuts are not an essential part of a dog’s diet, feeding them occasionally in very small amounts can offer a few minor benefits.

1. A shinier, healthier coat – Hazelnuts contain omega-6 fatty acids, which play a role in maintaining a glossy, soft coat and healthy skin. These fatty acids help support the skin’s natural barrier, reducing dryness and flakiness. However, there are far safer and more reliable sources of healthy fats for dogs, such as fish oil or flaxseed.

2. Improved brain and nerve function – Vitamin E and magnesium found in hazelnuts may contribute to better nerve health and cognitive function. Vitamin E acts as an antioxidant that protects cells from damage, while magnesium supports the nervous system and muscle function. 

For senior dogs, these nutrients could offer mild support for brain health, but they are best sourced from dog-safe foods and supplements.

3. Extra energy – The natural fats and proteins in hazelnuts can provide a quick energy boost, especially for active dogs. However, the high-fat content means they should only be given sparingly to avoid digestive upset or unnecessary weight gain.

Some owners use a small piece of crushed hazelnut as a special, high-value training reward for dogs who don’t respond well to standard biscuits. The unique taste can make it an exciting, occasional treat.

Even with these potential perks, it’s important to remember that hazelnuts should never replace balanced, dog-formulated nutrition. The benefits they offer are minimal compared to safer, more appropriate treats made specifically for canine health.

Risks of Feeding Hazelnuts to Dogs

Unfortunately, the risks of hazelnuts often outweigh their benefits. Here’s why:

• Choking Hazard – Their size and hardness make them risky for smaller dogs.

• Digestive Upset – High fat content can cause diarrhea, vomiting, or pancreatitis.

• Mold Contamination – Old or improperly stored hazelnuts may develop mold containing aflatoxins, which are toxic to dogs.

• Salt and Flavorings – Many hazelnuts sold for human consumption are salted, roasted in oil, or coated in chocolate, which can be harmful or even deadly.

Because of these risks, hazelnuts should be treated as an occasional snack at most, not a regular treat.

Symptoms of Hazelnut-Related Illness in Dogs

If your dog eats hazelnuts, especially in large amounts or with flavoring, watch for the following symptoms:

• Vomiting

• Diarrhea

• Lethargy

• Loss of appetite

• Abdominal pain

• Coughing or choking (if the nut gets stuck in the throat)

In severe cases, particularly if moldy hazelnuts were consumed, symptoms may include tremors, seizures, or jaundice. If you notice any of these signs, contact your veterinarian immediately.

How to Feed Nuts to Your Dog Safely

If you decide to let your dog try hazelnuts, follow these safety tips:

• Choose plain, unsalted nuts – Avoid flavored, salted, or chocolate-covered hazelnuts.

• Crush or chop the nut – This reduces the risk of choking and makes digestion easier.

• Limit quantity – No more than 1–2 small pieces for a medium-sized dog.

• Introduce slowly – Give a tiny portion first to check for allergic reactions or digestive upset.

• Supervise – Always watch your dog while they’re eating nuts.

Better yet, consider dog-safe alternatives or custom meal plans that incorporate safe treats and ensure proper nutrition.

Finally

So, can dogs have hazelnuts? Yes, but only in small, plain, and carefully prepared amounts. While they offer some nutrients, the potential risks mean they should never be a regular part of your dog’s diet. When it comes to treats, there are plenty of healthier and safer options designed just for dogs.

Remember, your dog’s safety and health always come first. When in doubt, skip the hazelnut and reach for a tailored, vet-approved meal plan from Petly that’s safe and nutritious.
