Trained animals should have a chance to drop taming collars

So in the world of New Brittania there are some animals out there that are tied to different factions, and fight on their behalf. The trained wolves in road encounters, the giant grizzly bears that the bear clan uses, and the grave keeper hounds in the rise for example. However,I think these creatures should either drop Taming collars or at the very least animal collars, to show that they are in fact trained. Maybe it's not a guarenteed chance but it should be there. It would add to the lore and the immersion in the game and help show that the enemies work on a similar system to what we do. Perhaps you could also make the npc's that are around these trainers drop animal whistles to show they are training them. Just a thought @Lord British to help make the game even better on those levels
