The Shaggy Dog is a 2006 American science fantasy family comedy film directed by Brian Robbins and written by The Wibberleys, Geoff Rodkey, Jack Amiel, and Michael Begler.

It is the fifth overall and final installment of the titular franchise and is a reboot of the 1959 film of the same name and its 1976 sequel The Shaggy D.A., both of which were loosely based on the 1923 novel The Hound of Florence by Felix Salten.

The original film had a character named Wilby Daniels transforming into an Old English Sheepdog after putting on a magic ring whereas the remake presents a character named Dave Douglas transforming into a Bearded Collie after getting bitten by a sacred dog.

It stars Tim Allen, Robert Downey Jr., Kristin Davis, Danny Glover, Spencer Breslin and Philip Baker Hall.

Geneticists working for company president Lance Strictland, led by Dr. Marcus Kozak, have stolen Khyi Yang Po, a 300-year-old sacred dog (a Bearded Collie) from a Tibetan monastery.

Khyi Yang Po's genetic sequence, when isolated and put into a vaccination, alters the cells and DNA of a victim.

Over the next days, Dave realizes that he uncontrollably transforms into a sheepdog like Shaggy when prompted by distractions and activities typical of a dog, such as a stick thrown through the air and chasing cats.

Dave returns home, still in his canine form, and overhears a conversation between Carly and her brother Josh.

His kids attempt to save him, but end up picking up Shaggy instead and rush to Rebecca at work to report recent events.
