I don't believe the     WDT on/off state is under program control in any way
whatsoever.  That would defeat its purpose, no? In the parallax programmer
you can *program* the part with WDT ON or OFF, it's your choice.
Putting a CLRWDT everywhere there is a loop or delay kind of defeats the
purpose of the watchdog also, doesn't it?  Isn't "good" practice to put the
CLRWDT in the main program loop only, where you know the program is almost
assuredly working normally?  Otherwise, how do you know the program is
running properly?  It might be in an endless loop that calls the routine
where you have inserted the CLRWDT, especially if your program employs
interrupts.
