Salky hounds represented a genetically modified version of kath hounds achieved through selective breeding. This process led to the creation of creatures known for their extreme aggression and unmanageable nature. A promotional flyer for Vontor's Eve events, presented to Grakkus by Toren, initially showcased a salky hound competition. A duplicate of this advertisement found its way into the Smuggler's Guide while Toren had the book.
The inaugural reference to a salky hound within the new Star Wars canon appeared in the 2016 Star Wars Roleplaying sourcebook Savage Spirits, released by Fantasy Flight Games.
