how can I use the watchdog as a periodic timer?

The information i've found in the manual is:
"The Watchdog Interrupt Flag is set when the watchdog times out. This flag
is cleared when any reset occurs."

Due to this it isn't possible to clear the Watchdog Interrupt Flag by software.
But when I can't clear this flag, I can handle this interrupt only one time and
that wouldn't be sense of a periodic timer.
