Tim Allen transforms from family dad to family dog and back again in this fresh update of the Disney comedy classic, “The Shaggy Dog”. It all begins when a workaholic Deputy D.A. Dave Douglas (Tim Allen) takes on a case involving an animal laboratory – one that will take him away yet again from his wife (Kristin Davis) and kids (Zena Grey and Spencer Breslin), who already yearn for his all-too-distracted attention. But when Dave is accidentally infected with a top-secret, genetic mutation serum, everything he thought he knew about being himself and his family changes. Yet with his newly perked-up ears, and his front-row seat on the household carpet, Dave is able to gain a whole new perspective into his family’s secrets and dreams. Now, he wants nothing more than to stop fetching and return to fathering – only first he’ll have to stop the evil forces behind the serum… in an adventure that will bring the whole family together.
