None! It’s not a good idea for your pet to eat Chocolate meant for human consumption. However, if your pet does accidentally eat Chocolate, he/she would need to eat in excess of 50gms of Dark Chocolate, (80 gms Milk Chocolate) per 10 kg bodyweight to become intoxicated. Severe intoxication can lead to heart failure and death, so if your dog has eaten a significant amount of Chocolate, seek veterinary care immediately.
