I have a dog I called SNAPPER, and when I interact with him I get the twig snapping sound effect you get when you fail to sneak.
I have a dog I called GRUNT, and when I interact with him I get the wild boar grunting sound effect.
I am going to call my next dog FARTER, just to see what happens.
I think I may be losing my grip on reality... becoming Unreal, if you will.
Note: Dog names are in capitals in the game as that's how I roll, easier to see them in the combat text logs.
