Dogs can react differently depending on their size, age, health, allergies, medications, the amount consumed and other circumstances. An item classified as Safe is not necessarily suitable for every individual dog.
If your dog has eaten something potentially poisonous or dangerous, has eaten an unknown substance, or is showing concerning symptoms, contact your veterinarian or an emergency veterinary service immediately.
Do not induce vomiting or give your dog medication unless specifically instructed to do so by a veterinary professional.
