It depends...

Some AVR chips, for example atmega164/324/644p, have three watchdog modes:

   1 - Interrupt mode

   2 - System reset mode (a WD timeout in this mode is equivalent
       to a "hard reset")

   3 - A combination of the above, interrupt + system reset

Have a look in the data sheet and make sure that you have enabled the
correct mode.
