Why can’t dogs eat chocolate and grapes?

Chocolate contains caffeine and theobromine. These substances can cause vomiting, diarrhea, rapid heartbeat, severe chicken cramps, and even shock in dogs; grapes can also cause acute renal failure in dogs. In this case, these two foods can cause the death of dogs, so chocolate and grapes cannot be given to dogs.
Tip:
In addition to chocolate and grapes, products containing these two foods cannot be given to dogs.
