No matter, how good you write your firmware/software. There are always unexpected situations like your program may stick in an infinite loop, hung somewhere or hardware burn-out/failure. To combat these unexpected situations, we need some circuitry that keeps monitoring the main system/application and in case of unexpected events, it restarts the system. Even the windows-like operating system use the watchdog timer.
