Give chocolate to loved ones, and you could end up poisoning them. That is, if the loved one is your pet dog. Even small amounts of theobromine, an ingredient in chocolate, can cause vomiting and restlessness in pets.
Larger doses can be fatal.
While most pet owners expect a dog to develop an upset stomach after eating a large amount of chocolate, few realize its danger or toxic potential. The lethal dose of theobromine depends on the size of the dog and the type of chocolate. Ounce for ounce, baking chocolate has six to nine times as much of the substance as milk chocolate does. 8 ounces of milk chocolate or 2 ounces of baking chocolate for medium-sized dogs, like cocker spaniels and dachshunds. 8 ounces of milk chocolate or 4 ounces of baking chocolate for large dogs, including collies and Labrador retrievers.
