Carly brings Khyi Yang Po, who she calls ‘Shaggy’, home. When Dave returns from work, he takes Khyi Yang Po out in the garage, then the dog runs to get the newspaper. Khyi Yang Po gives him his newspaper, and Dave reaches for it, only to be bitten on the hand by Khyi Yang Po. Khyi Yang Po's saliva and cells infect Dave and is taken to be tested for rabies and the tests came back negative. Over the next few days, Dave realizes that he uncontrollably transforms into a sheep dog exactly like Khyi Yang Po when prompted by distractions and activities typical of a dog, such as a stick thrown through the air and chasing cats. These transformations can be reversed by sleeping, but Dave's human absence from his family further strains his relationships. During this time, his family, unaware of Dave's condition, continue housing Dave as a dog, thinking it's Khyi Yang Po. Dave slowly learns just how little he understands his kids and wife and resolves to make amends.
