No, dogs should not eat chocolate. Chocolate contains a compound called theobromine, which can be toxic to dogs. The amount of theobromine varies depending on the type of chocolate, with darker chocolates containing higher amounts. Theobromine can cause a range of symptoms in dogs, including vomiting, diarrhea, restlessness, rapid breathing, muscle tremors, and seizures. In severe cases, it can even cause death. Therefore, it's best to keep chocolate away from dogs and opt for dog-friendly treats instead. If you suspect that your dog has ingested chocolate, you should contact your veterinarian immediately.
