Violetta

 is a Fiend guard dog living in the Mojave Wasteland in 2281.

Quests
Violetta is one of Violet's guard dogs. Using her brain raises Rex's speed when you transplant it to him in Nothin' But a Hound Dog. This is because Violetta was given lots of turbo. Rex will not be addicted or need to use turbo because of this fact though.
