No, dogs should not eat hickory nuts.
Hickory nuts come from trees of the same name. They fall under the genus Carya and belong to the same family as walnuts (Juglandaceae). These plants are found in a variety of temperate regions such as China, United States, and India. With around 18 recognised species, some hickory plants are used for wood and edible produce. Their nuts grow in bone-hard husks that open when they mature.
For dog owners, it’s a relief to know that the hickory nut is non-poisonous to dogs. But when consumed, hickory nuts can cause airway/intestinal obstruction as well as gastrointestinal distress. Obesity and pancreatitis may even occur if these nuts are eaten in large quantities. Plus, juglone—a harmful chemical—is found on the shells and other parts of the hickory tree.
What to do if your dog accidentally eats hickory nuts: If he accidentally eats a piece of unshelled and unseasoned hickory nut, he should be alright. But observe your pet closely over the next 24 hours to make sure he’s okay.
If he accidentally ate too many hickory nuts, he may experience diarrhea, vomiting, dehydration, and greasy looking stool. Additionally, moldy hickory nuts can cause neurotoxicosis due to the tremorgenic mycotoxins found in them. Symptoms include stomach pain, dilated pupils, and uncontrolled flickering eye movement. Elevated heart rate, hypersalivation, fever, tremors, and vomiting may also manifest.
In summary: Hickory nuts consist of fats, carbohydrates, protein, and water. Even if they are a rich source of B vitamins and select minerals, these large-sized nuts should not be consumed by dogs.
