First time posting anything here and didn't see this posted so, here goes.
You get the item Fiery Leash (Fiery Leash - Item - World of Warcraft) from the quest Walking the Dog (Walking the Dog - Quest - World of Warcraft) from Instructor Devoran (Instructor Devoran - NPC - World of Warcraft) in Mount Hyjal.
It summons a core hound pup, Spawn of Smolderos (Spawn of Smolderos - NPC - World of Warcraft), that auto attacks anything that attacks you with a mini flame breath that does about 257 damage per second. Not much, but a free combat pet is a free combat pet.
Currently, he's summonable outside of the zone. He stays out while mounted and doesn't despawn until you use the Fiery Leash again or he's killed. The item has a 2 sec cooldown so you can bring him back as soon as he's killed. Just don't turn in the quest and you got a core hound pup pet.
He makes a crappy tank, but on a 2 sec cooldown you can resummon instantly after death and if you have the patience to tag a mob and let him hold aggro, you get all the xp.
Hope somebody finds this useful.![]()
