You may clear WDT from periodic interrupt, say your system tick if you have one. Higher level task tells ISR how many times (ticks) it can keep clearing WDT without being pinged from that task. Obviously your system will have to wake up from LPM3 to service tick ISR and tick needs to be shorter than 1s.
