This is Dr. Christian. Welcome to JustAnswer. None of these herbs are dangerous for dogs in small amounts. Large amounts could cause gas, vomiting or diarrhea. However, make sure to avoid anything in the onion family (garlic, chives, onions) since these are toxic to dogs and can cause anemia. Otherwise, let them enjoy it and it might even improve their breath. If you have more questions please let me know.
