Yes, the sense of Live is fun. It's good to know that there are more Lives than only one. Our Dobermann Lucky is died and I hope he lives again somewhere and has fun again.
If you've read the book then you'll know how much of a "fingers down the throat Disneyisation" this film is. The first incarnation of this dog in the book was arresting with the cute narration of the dog juxtaposed against it trying to figure out the gas chamber it was in. That was a thud, and only about 5 pages into the story. Odd that the film makers may have thought that this might be too harrowing and gut-wrenching a scene yet didn't think twice about nearly actually drowning the German Shephard.....
