The Shaggy Dog plot
"It's going to be a ruff day."
Lawyer Dave Douglas (Tim Allen) hardly has time for his wife and children as he is busy with a case surrounding a mysterious animal laboratory. When his daughter takes home a 300-year-old dog from Tibet in protest against the experiments in the lab, her father is bitten by this dog. This bite causes Dave's body to turn into a dog out of nowhere. This literally gives Dave a different view of himself, but also of his family. He discovers that he wants to be a better father, but first he has to get Dr. Unmasking Cossack.
