How so? In both cases you have to "know" what class $obj is/can be.

my Dog $spot;

Gives as much or as little information to either. 

   $spot->{'tail_colour'}
or 
   $spot->bark;

You either look in $Dog::FIELDS{'name'} or CV of $Dog::{'name'} 
(Perhaps %FIELDs should have been part of the stash ...)
