I was found by Elroy in the fourth Jetsons episode, "The Coming of Astro". When Elroy, Jane and Judy proposed keeping me to George, he was against it. To try and stay out of the "doghouse" with his family, he got an electronic dog. The electronic dog was supposed to be the new hairless, non-eating, protect your house, way to go. When a cat burgler tried to rob the Jetsons, the electronic dog attacked him (which he did to anyone wearing a mask). Elroy tried waking me to get me to stop the burglar as a way to prove myself, but I turned out to be more interested in hiding in fear. However, when trying to escape, the cat burgler put the mask on George. The electronic dog then proceeded to chase after George. It was I (who was trying to run from the cat burgler) that inevitably caught the criminal (by accident) by crashing into him. This prompted George to decide that the electronic dog was not the way to go. They gave the electronic dog to the police and kept me as part of their family.
In the fifteenth episode, "Millionaire Astro", I am discovered to be Tralfaz, the long-lost pet dog of zillionaire J.P. Gottrockets.
