All I Want for Christmas Is You (2017)

Young Mariah's Christmas wish is crystal clear the moment she lays eyes on the adorable puppy, "Princess," at the local pet store. However, there's a catch—before her festive dream can materialize, Mariah must showcase her dog-sitting skills with her uncle's unruly canine companion, Jack. A mischievous rascal and self-proclaimed titleholder of the "worst dog in the county," Jack becomes the unexpected hurdle on Mariah's path to making her Christmas wish a reality.
