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 workaholic D.A. Dave Douglas (Allen) takes on a case involving an animal laboratory - one that will take him away, yet again, from his wife (Davis) and kids, 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.
