Chocolate is a sweet treat that is enjoyed by many humans, but it is not safe for dogs to consume. Chocolate contains a substance called theobromine, which is toxic to dogs. The amount of theobromine in chocolate varies depending on the type of chocolate and the amount consumed, but even small amounts can cause vomiting, diarrhea, and excessive thirst in dogs.
In extreme cases, chocolate poisoning can lead to seizures, heart problems, and even death. It is important to keep all chocolate products out of reach of dogs, and to seek veterinary care immediately if a dog has ingested chocolate.
Safer alternatives for dogs include dog-specific treats and snacks, as well as fruits and vegetables such as apples and carrots.
