The Core Hound is most likely modelled after Cerberus - the mythical beast who guards the gates of hell.

Since we now receive a Core Hound pet along with having an Authenticator, you could say that it's the one guarding your account from potential threats. :)

If this pet still has the idle animation of scooting its bum across the ground, I'm pretty sure it stands for 'wiping' (as PUG groups tend to do). ;)
