This is a truly remarkable story of reincarnation involving your little Spot. A story which begins in California and finishes in Australia, where you and your sister live with Spot now.
I assigned her the pet-name of "Spot Jackterrier", which I then discovered was an anagram of: "Apricot Jest Kerr".
In her previous existence, little Spot's name was "Apricot Jest", and she lived in the late 1920's with the Kerr Brothers, who owned a thriving apricot orchard in Moorpark, California. They had named her after their business, and the fact that she was (as is the nature of the Jack Russell breed) a bit of a trickster. All of the Kerr Brothers' customers knew Apricot Jest well, and she was a familiar, welcoming sight to all who would come to visit.
She was such a success at being the perfect Jack Russell terrier, that her little soul requested that she be born a Jack Russell again. And so Apricot Jest was born again, in Australia this time, and you came to own this best-beloved little dog from the famous Kerr Brothers' apricot orchards of the 1920s.
Here is a website, where you can go to verify the fact that the Kerr Brothers owned an apricot orchard in Moorpark, California:

Unfortunately, there is no mention of little Apricot Jest on this website, but that's okay with Apricot Jest. Her greatest joy -- in that life, as well as in her present life -- is bringing pleasure to her owners. :)
