This dog got his name from the Star Wars character Chewbacca. How appropriate since it was Star Wars creator George Lucas' dog who inspired him to create Chewbacca. And, the name is derived from the Russian word for dog. One more tidbit of trivia, Lucas' dog is named Indiana, and yes, the name was used for the Indiana Jones movies! Meanwhile, back to this Chewbacca. Two to three years old and a Chow Chow-Collie mix, Chewbacca arrived as a stray on October 10th at the Surry County Animal Control shelter in North Carolina. The shelter was able to locate and notify his owner, but the owner didn't want him back. And that's a good thing considering that Chewbacca had been kept on a chain his whole life. Not surprisingly, he tested heartworm positive.
