Toblerone or any chocolate is perilous for dogs. Chocolate contains theobromine, which can be toxic to them. Toblerone, in particular, has higher cocoa content, making it more dangerous. Even small amounts can lead to vomiting, diarrhea, increased heart rate, seizures, and even death in dogs. I experienced this with my own dog when he accidentally consumed a piece of chocolate. It’s crucial to act fast and contact a vet immediately if your dog ingests Toblerone or any chocolate. Keep chocolates and other human treats out of their reach, and always prioritize their safety.
