Does anybody know chocolate can cause toxic/death to our pets?

The main culprit is, a compound present in chocolate i.e., theobromine. Theobromine poisoning or chocolate poisoning occurs mainly in dogs, but occasionally this type of poisoning occurs in cats and other domestic animals.

Theobromine is a bitter plant alkaloid which is found in cacao plant, having the chemical formula C7H8N4O2. It is commonly found in chocolate, as well as in leaves of the tea plant, and the cola nut/ kola nut (1.0-2.5%). Theobromine has a similar, but lesser effect when compared to caffeine on the human nervous system.

Theobromine can also be found in small amounts in guarana berry and in tea plant. 28 grams of milk-chocolate can accommodate approximately 60 milligrams of theobromine but 28 g (1 oz) of dark chocolate accommodate about 200 mg (3.1 gr).
