Yes, white chocolate is worse for dogs compared to dark chocolate. While both contain theobromine, the compound toxic to dogs, white chocolate has lower levels than dark chocolate. However, any amount of theobromine can harm dogs. Theobromine affects a dog’s nervous system and heart. Even a small quantity of white chocolate can lead to symptoms like vomiting, diarrhea, increased thirst, restlessness, and in severe cases, seizures or heart issues. It’s crucial to avoid feeding any kind of chocolate to dogs and seek veterinary help immediately if ingestion occurs. Based on my experience, preventing access to chocolate is crucial for a dog’s well-being.
