Rent In the Dog House (2014)

A howlingly funny movie about two siblings using their dog to bring their estranged parents back together. Recently divorced mom Wendy has decided it's time to move on and start dating again. Her daughters, Amanda and Martha, are horrified at this prospect and, with help from their dog Irving, set out to sabotage all prospective boyfriends. When the family strikes it rich by winning the lottery, Wendy's old high-school sweetheart suddenly arrives on the scene with his own dastardly idea - kidnap the dog and then pretend to rescue it in order to win the love of Wendy! When the girls find out, they do everything in their power to stop this plan and reunite their parents.
