Your furry friends are very curious eaters, and that is why you have to be extremely careful of what they eat. When they see you eat something, they might want a bite too. As dog owners, it is important to know which foods are safe for your furry friend.
The most important question is: Can dogs eat walnuts?
And the simple answer is No. Walnuts can be toxic to dogs and can cause serious health problems.
Why Are Walnuts Bad for Dogs?
Walnuts are very nutritious nuts, but they can be very dangerous for dogs for several reasons. Here are the main concerns:
1. Hard to Digest
Walnuts are large and tough. Dogs may have trouble chewing and digesting them properly. This can lead to stomach problems, vomiting, or even blockages in the intestines.
2. High in Fat
Walnuts contain a lot of fat. Healthy fats are good for humans but too much fat can be harmful to dogs. Eating fatty foods can lead to pancreatitis, a painful condition where the pancreas becomes inflamed. Pancreatitis can cause vomiting, diarrhea, and loss of appetite in dogs.
3. Mold & Toxins
One of the biggest dangers of walnuts is that they can develop mold. Moldy walnuts, a type of walnut, can contain mycotoxins, which are highly poisonous to dogs. These toxins can cause seizures, tremors, and other serious health problems.
4. Juglone Poisoning
Black walnuts, a type of walnut, contain a chemical called juglone. Juglone is toxic to dogs and can cause poisoning if eaten in large amounts. Even though regular walnuts contain less juglone, they can still be harmful.
5. Risk of Choking
English walnuts, a type of walnut, can cause weight gain, obesity. Because walnuts are large and round, they can be a choking hazard, especially for small dogs. If a walnut gets stuck in a dog's throat, it can block their airway and make it difficult to breathe.
Symptoms of Walnut Toxicity in Dogs
If a dog eats a walnut, the effects will depend on the amount eaten and whether the walnut was moldy or not.
Here are some symptoms to watch for:
-
Vomiting
-
Diarrhea
-
Stomach pain
-
Loss of appetite
-
Weakness or lethargy

Difficulty breathing (if choking)
-
Tremors or seizures (if moldy walnuts were eaten)
If your dog shows any of these symptoms, contact your veterinarian immediately.
