In our datamining of The War Within Alpha, we've discovered that our Faithful Dog has made their way to Khaz Algar, becoming a full-fledged companion, so that players will never again have to leave their pet behind!
First introduced in Mists of Pandaria, the eponymously named Dog was first introduced at the Tillers Farm in Valley of the Four Winds, an almost insignificant addition if not for its unique response to emotes like /pet or /love. Becoming attached over the course of the expansion, many players expressed sadness at leaving their unofficial pet behind, though were delighted to find that the faithful canine followed them into Warlords of Draenor, adopting a new home in the player Garrison.
Fast forward to Legion and Dog was once again left behind as players moved on to the Broken Isles, though a series of hints from then Game Designer Muffinus led players to discover that their dog could follow them to the streets of Dalaran. Unfortunately, this is the last we saw of Dog as the game advanced into Battle for Azeroth, Shadowlands, and Dragonflight, though seemingly comfortable and well taken care of within Breanni's pet shop.
While The War Within begins with the disastrous Fate of Dalaran, we're pleased to learn that our Faithful Dog has not only survived, but will become a full-fledged companion, so that players will never again be parted from their beloved pet.
Despite being listed as a battle pet, Dog is a lover, not a fighter.
