Might help to establish which Generation they are as well.
There are currently 4 Generations of WWs.
Gen 1: "Ancients". These refuse to eat gold, roar when commanded (
https://uo.stratics.com/hunters/sounds/dragon1.mpg), and have an extremely aggressive AI. Only six "Ancients" are confirmed to still exist in game so far.
Gen 2: "Legacies". These refuse to eat gold, yet grunt when commanded.
Gen 3: "Pre-Patch". These eat gold, grunt when commanded, and could spawn with up to 760 STR at 3 slots (like the previous generations).
Gen 4: "Revamp". These eat gold, grunt when commanded, but spawn with half the minimum STR (360, which is a 3 slot), and are 4 slots when spawning with higher STR.
