<P> Astro is a canine character on the Hanna - Barbera cartoon , The Jetsons . He was designed by Iwao Takamoto , and originally voiced by Don Messick . Despite the stress he tends to cause him , George often regards Astro as his genuine best friend . Astro , despite being clumsy and dim - witted , was very loyal ( to a fault ) to the Jetsons , particularly George and Elroy . He was more advanced than present - day dogs , in that he had a rudimentary grasp of the English language . In a recurring gag , while George is walking Astro on a gravity - suspended treadmill , Astro begins chasing a cat that stumbles onto it , eventually forcing it to go at speeds too fast for George to keep up with , trapping him . This led to George 's trademark phrase `` Jane ! Stop this crazy thing ! '' . </P>
