What do you do if a dog eats a walnut shell?

If a dog eats a walnut shell, monitor them closely for any signs of distress, such as vomiting, diarrhea, or abdominal pain. Walnut shells can pose a choking hazard or cause intestinal blockages. If you notice any concerning symptoms or if the dog ate a large amount, contact your veterinarian for guidance. It's always best to err on the side of caution when it comes to your pet's health.
