Well, that didn't take long.

Many were upset after the gruesome ending to Brian Griffin's life on Sunday night's episode of Family Guy. Let's face it, no one saw that coming a million miles away.

Was it a plot twist to grab ratings for the remainder of the show's season? Was it actually time to move on from Brian on the show? We guess time will only tell but some fans are very, very upset at losing a key character on the show.

So much so that Aaron Thompson has created a Change.org online petition to get Family Guy creator (and voice of Brian Griffin) Seth MacFarlane and Fox to bring back the Griffin's beloved family dog.

The petition reads:

Brian Griffin was an important part of our viewing experince. He added a witty and sophisticated element to the show. Family Guy and Fox Broadcasting will lose viewers if Brian Griffin is not brought back to the show. Follow us here for updates on FACEBOOK.

The writers of family guy didn't just kill off one of their creations, they killed off the dog who has lived in our homes for the last 15 years. They killed the dog we all have come to love. They killed America's dog!

If you feel as "outraged" as Aaron, you can join the more than 30,000 other fans by signing the petition HERE.
