A fictional dog breed I call the Swiss Guarding Retriever. From lines of Canadian line Greater Swiss Mountain Dog, English line Labrador Retriever, Maryland line Chesapeake Bay Retriever, German line Rottweiler, and American line Bullmastiff. A dog that can scare off an intruder, but also safely deliver lost objects for their owner, that has a loyalty to their family. Not for a first time dog owner or the faint of heart. #fictional #breed #guard #retriever #large #dog #working
