Don't know your dog's breed?

Wondering “Can dogs eat walnuts?” It's tempting to share the tasty treat with your dog. Hit pause before you toss them a walnut. There are some important things to know. Walnuts are healthy for us. Yet, they pose certain risks for dogs. Let’s dive into why you might want to keep those walnuts for yourself. Explore safer alternatives for your pet.

Are Walnuts Safe for Dogs?

Quick answer: Generally, not recommended. While it might seem harmless to offer your dog a small piece of a walnut, don’t. Walnuts can actually cause more harm than good. Some people believe that nuts are a healthy option. Yet there are a few risks that make walnuts a risky choice. The biggest concerns are choking hazards. There is also the possibility of mold contamination. Their high-fat content can lead to digestive issues for your dog.

Why Some Dog Owners Consider Feeding Walnuts

Walnuts are packed with nutrients. These include omega-3 fatty acids, antioxidants and fiber. All these things are great for humans. But dogs have different dietary needs. A snack that's healthy for us might not be ideal for them. For example, the fatty content in walnuts might cause health issues. So, while the nutritional benefits are there, the risks just aren’t worth it for most dogs. Some pet owners have jokingly referred to their dog as a ‘walnut dog’ after seeing them munch on it, but it’s not a habit you should encourage.

Health Risks of Feeding Walnuts to Dogs

High Fat Content and Pancreatitis Risk

Walnuts are high in fat. Too much can lead to serious health problems. One of the most serious issues is pancreatitis. Pancreatic inflammation makes your dog very ill. Lethargy, appetite loss and vomiting are the symptoms that follow. Therefore, it is advised not to give walnuts to pups.

Toxic Mold Contamination

The possibility of mold growth is one of the main dangers. Stored improperly, walnuts can develop mold. Mycotoxins may be present in this mold. Dogs may have neurological issues as a result of this toxin. Uncoordinated movement, convulsions and tremors are the symptoms. Any of these could mean that your dog has consumed a mold-contaminated walnut.

Choking Hazard and Intestinal Blockage

Whole walnuts pose a choking hazard for dogs. This is especially true for walnuts with the shell still on. If your dog tries to swallow one of these whole, it could get stuck in their throat. This could lead to an emergency situation. Even shelled walnuts can cause intestinal blockages. This is especially true if eaten in large pieces. A blockage can require surgery to fix. It's best to avoid giving your dog walnuts to keep them safe.

Potential Allergic Reactions

Some dogs may have nut allergies. There are obvious signs when this happens:

Scratching excessively
Trouble breathing
Signs of swelling
Hives

Are Any Types of Walnuts Safe for Dogs?

English Walnuts vs. Black Walnuts

There are different varieties of walnuts. In actuality, some are more dangerous than others. For dogs, black walnuts are extremely poisonous. If consumed, these can result in major health problems. According to PetMD, a toxin called juglone is present in black walnuts. A study published by the American Veterinary Medical Association (AVMA) found that ingesting these causes clinical syndromes in canines with neurologic or musculoskeletal signs.

English walnuts are less toxic. But these still pose risks such as mold contamination. The choking hazards mentioned earlier are also a possibility. It is safer to simply skip giving dogs any walnuts at all.

Raw vs. Roasted Walnuts

Can dogs eat walnuts that are roasted? Are they any safer than raw ones? The truth is, roasting doesn’t remove the risks. Whether raw or roasted, walnuts can still cause problems. Their fat content, mold risk and choking hazards are the main issues.

Are Walnut-Based Products Safe?

There are walnut-based products such as walnut butter or walnut oil. These seem like healthier alternatives. However, they’re not safe either. High fat and potential mold contamination are still possible. Look for other types of safer treats for dogs.

Signs of Walnut Toxicity in Dogs

Early Symptoms of Toxicity

There is a chance that a dog may accidentally eat a walnut. When this happens, keep an eye on them. Look for any signs of toxicity. Early symptoms include vomiting, diarrhea, tremors or weakness. These appear within a few hours of your dog ingesting the walnut. Contact your vet right away if you notice any concerning symptoms.

Severe Reactions

There can be more serious reactions to walnut consumption. This happens when a canine eats moldy walnuts or consumes a large quantity. They may experience neurological problems like seizures. Liver damage can also be a consequence. Don’t hesitate to reach out to your vet.

What to Do If Your Dog Eats Walnuts

Act quickly. This is the most important thing. Stay calm and observe your dog. Notice any signs of distress. Vomiting or tremors mean calling your vet immediately. Inducing vomiting to prevent further issues is often suggested by vets but should only be performed under direct guidance from your veterinarian or directly at the clinic. For the best outcome, take immediate action.

Safe Alternatives to Walnuts for Dogs

How to Keep Your Dog Safe From Walnuts

Storing Walnuts Properly

To prevent accidental ingestion, store walnuts securely. Keep them in a sealed container. It should be in a place that your dog can’t reach. Avoid leaving them lying around where your dog might find them. Clean up any fallen walnuts regularly if you have a walnut tree.

Training Tips to Avoid Dangerous Foods

Teaching your dog the "leave it" command is another approach to keep them safe. This can help prevent your dog from consuming inappropriate foods. The dog won't eat them, whether they are on the counter or the floor.

Checking Your Yard for Walnut Trees

If you live near walnut trees, be extra cautious. Fallen walnuts are a real risk. Dogs are naturally curious. They might eat something they find, even if it’s not good for them. Check your yard regularly. Remove any fallen walnuts before your dog can get to them.

Final Verdict: Should Dogs Eat Walnuts?

Walnuts for dogs come with risks. The American Kennel Club recommends avoiding all nuts, as any nut can be unsuitable for your dog. Stick to safer, dog-friendly snacks.
