Dungeon Dog: Warrior

This creature is a 'dungeon dog', an especially breed canine used for delving into dungeons and labyrinths alongside adventurers. These dogs will sound the alarm when they pick the scent of other creatures, and can even sniff out treasure. They are also fiercely protective of their 'pack', laying down their lives to protect their companions. Dungeon dogs are hard to come by, and not given to just anyone.
Dungeon dogs are also renowned for their ability to withstand psychic attacks, and are even bred to hunt down and kill psykers.
