Astro

Astro is the Jetsons' family dog. Prior to being a Jetson, his name was Tralfaz and he belonged to the fabulously rich Mr. J.P. Gottrockets. Astro is one of George's best friends, next to his work computer, R.U.D.I., as well as Elroy's best buddy. He is able to speak in a rough sounding English resembling dog barks and growls, a manner of speaking which voice actor Don Messick would later reuse for the role of Scooby-Doo.
