Lab Rats (2012)

Adam brings a dog back to the island and Douglas reveals that it's his old dog, Otis, who Douglas made bionic in order to save his life when Otis was injured. Chase turns out to be allergic to dogs as he starts sneezing, so Douglas says that Otis has to leave, but he and Adam actually hide the dog. Meanwhile, Leo gets a new smartphone application assistant named Shelly, with whom he has fallen in love.
