Yes, even a small amount of white chocolate can be harmful to dogs. It contains theobromine and caffeine, both of which can be toxic to dogs. While white chocolate has lower levels of these substances compared to dark chocolate, it’s still safer to avoid feeding any chocolate to dogs. Consumption may lead to symptoms like vomiting, diarrhea, increased thirst, abnormal heart rhythm, tremors, seizures, and in severe cases, it could be fatal. If your dog has ingested white chocolate, monitor for any unusual behavior and contact a vet immediately for guidance. It’s crucial to keep chocolate and other potentially toxic foods out of your dog’s reach for their safety.
