_{This character has no official visual representation in any Transformers product or media... yet, at least.}

Yeller is a mangy good-for-nothing (but well-loved) yellow Labrador retriever even more ancient and decrepit than his owner, Jake Williams (in dog years). Yeller is riddled with cancer and not long for the world.

He likes to chase rabbits and watch his owners have sex.
