Safety status
What this means for your dog
Safe for dogs — ASPCA lists bitternut hickory as non-toxic to dogs and names no toxic principle. The bigger yard concern with hickories is a dog swallowing a hard nut whole (a choking and obstruction risk), not the leaves or bark themselves.

Questions about Bitternut Hickory
Is Bitternut Hickory toxic to dogs?
Bitternut Hickory (Carya cordiformis) is considered non-toxic to dogs. It is generally safe, though that does not mean it is beneficial for them to eat.
What happens if my dog eats Bitternut Hickory nuts or leaves?
No toxic effects are expected. However, if your dog consumes a large amount of the fibrous plant material, mild vomiting or diarrhea may occur due to the bulk and fiber content, not any toxic compound.
How much Bitternut Hickory would cause a problem for my dog?
Small nibbles are unlikely to cause any issue. Problems, if they occur at all, would stem from eating a significant quantity of fibrous material, which can upset the digestive tract — not from any toxin in the plant.
What should I do if my dog ate a lot of Bitternut Hickory?
Monitor your dog for vomiting, diarrhea, or signs of digestive discomfort. Since the plant is non-toxic, serious harm is not expected, but if your dog shows prolonged distress or ate a very large amount, contact your veterinarian for guidance.
