Exotic Family : You must be specced as a Beast Master to tame and use Core Hounds!
A sleeker, one-headed version of the core hound. These beasts are associated with the Dark Iron Dwarves and we don't yet know if they'll become generally tameable.
It's too early to confirm whether this creature will be tameable in the next expansion.
These ostensible core hound relatives are currently all classed as demons.
