Dana's Ninetales is Dana White's only known Pokémon, who she took care of after finding injured near her home. Her parents, Mr. and Mrs. White, tried to take Ninetales away in hopes of Dana to return back to her spoiled and snotty way, sadly, it didn't work.
Ninetales was found by a young Dana as a Vulpix injured near her home in Hau'oli City of the Alola region. Vulpix managed to change Dana from being snotty and spoiled to nice and caring and making sure others are doing OK. Vulpix liked the change, while Dana's parents did not. Vulpix defended Dana from her parents and despite Dana getting disowned, she still lived on her property but in a house that her parents had built.
Vulpix went with Dana when she turned 13 and traveled to the Kalos region and then met Caleb Montgomery who helped them capture a Scatterbug. They took Caleb's invite to travel with him and his Charmander. Eventually, Dana evolved Vulpix into Ninetales.
It is unknown when Ninetales is set to appear, but in Kalos 1: Starting Journey, she is mentioned by Scarlett Montgomery when she tells Bailey Ketchum about getting her Vulpix, as being the offspring of Dana's Ninetales.
