It is true that watchdogs can be useful for some types of software.  But 
if a watchdog is useful, it is because the code has bugs, the system has 
design flaws, or it is being used in a way that was not intended by the 
specification and design.  If you are aware that this is what you are 
protecting against, then it may be worth enabling the watchdog.

And if you have a watchdog, then you need a sort of mechanism like you 
describe here - tracking the watchdog restarts and going into a safety 
or recovery mode rather than blindly restarting the system again and 
again.  In particular, it is vital to learn /why/ the watchdog was 
triggered - that is what gives you the knowledge to try to fix the flaw.

But if the watchdog is being triggered during your startup code from 
reset, before you have even reached main(), then the code should never 
have left the development lab.  Therefore a watchdog that is enabled by 
reset is counter-productive - it cannot possibly help, and it can 
certainly cause problems.
