Can be tamed.
Located in Horde Airship, Drustvar. Alliance hunters that are able to tame undead will be able to tame this skeletal hound in the usual way, but it is friendly to Horde and can only be tamed by Horde hunters using the toy "N'lyeth, Sliver of N'Zoth" while in War Mode. These hounds only appear during Horde assaults on Drustvar. Two can be found on the Horde airship, just north-east of Arom's Stand, in the company of Kaldras Snape. They're located just below decks in the stern of the ship.
