The Shaggy Dog (2006)

Woof! Aw shucks, I guess it was perfectly watchable and mildly entertaining. They really tried hard to make the events in the movie “believable” – not that the premise is remotely believeable, but little things like the way he has a hard time convincing people he’s a dog, and that fact that eventually he does, and it’s prior to the climax of the movie.
