Yes, milk chocolate can harm dogs. I want to highlight that chocolate contains theobromine and caffeine, which are toxic to dogs. The amount of theobromine in chocolate can vary based on the type, with darker chocolate posing more significant risks due to higher concentrations. Even small quantities of milk chocolate can cause symptoms like vomiting, diarrhea, increased thirst, restlessness, rapid breathing, and in severe cases, it can lead to seizures or even death. If a dog consumes any chocolate, it’s essential to contact a vet immediately for guidance and treatment. Based on my experience, never give chocolate to dogs as it can be harmful to their health.
