It is common knowledge that chocolate is dangerous to dogs. However, many people don’t understand why it is dangerous. Both caffeine and theobromine are found in chocolate. They are both stimulants that can lead to medical issues in your dog. They could even kill your dog. The amount of caffeine and theobromine found in each type of chocolate can help determine how dangerous it is to your dog. Milk chocolate has a fairly low concentration whereas semi-sweet chocolate is higher. The highest concentration of all is found in baking chocolate. The quantity of chocolate your dog eats and his body weight are factors too. Signs of chocolate toxicity include vomiting, diarrhea, rapid breathing, increased heart rate or seizures. If your dog eats chocolate, seek urgent medical treatment. Don’t feed him chocolate and keep it out of reach. Ensure guests know to keep chocolate away from your dog especially during parties.
