I've found the perfect website for my wife (who is the ultimate animal lover). There is a new website that tells you if a pet is injured or dies in a movie:

My wife will not watch a movie if she knows (or even thinks) an animal dies or is abused in said movie. I am also an animal lover (just one who understands movies are make believe...just sayin honey). If you are like my wife, there's a great website you might want to start visiting.

DoesTheDogDie.com tells you if an animal dies in a movie. It actually has three different ratings for movies. No pets die, A pet is injured or appears dead but ultimately lives, and the dreaded A pet dies.
