Ancient Core Hounds will no longer respawn after you've killed Magmadar, the second boss in Molten Core.

They patrol within MC, and have a fairly quick respawn timer. You will need to dispatch them quickly, make sure to skin for the Core Leather, and move on.

Note that they do no despawn when you've killed Magmadar, they simply won't respawn again after you've killed them.
