A "watchdog" is a working dog that is kept to protect property, like a home, land, or other animals. The term "guard dog" also means the same thing. Ex: A suspicious man walked past the farm, causing the watchdog to start barking. Ex: We live in an isolated area, so we have a guard dog to protect us.
