in dave (tim allen) TimAllen in his heart, work is always the first priority, and his wife and children at home have to give way in front of his career. if it weren't for this accident, maybe he would never realize the importance of his family. after receiving an animal experiment case, dave started an investigation, but unexpectedly dealt with a long-haired dog: the long-haired dog bit him and spread a bizarre virus that re-modeled his genes. now, dave becomes a long-haired dog, and the long-haired dog becomes dave. their lives also changed with each other. no one in the family knew that the pitiful and cute long-haired dog was his relative. dave could only live a dog-faced and heart-warming life, watching the long-haired dog with zero iq occupy the position of the head of his family. what is even more worrying is that dave, who became a dog, finally had the time to watch how his family lived, and finally realized that the love he had given them was too little in the past. but with dave's current situation, it seems that he only regrets it. eee
