WARNING: SPOILERS! Family Guy shocker as character killed off
He's been a stalwart of Family Guy since the beginning, but it's finally the end for Brian the dog.
Stewie's best friend and Peter's partner in crime meets his end after being hit by a car in the latest episode of the hit animated series.
His death is a shocker for fans throughout the world and Twitter users have been expressing their grief online.
Executive producer Steve Callaghan explained the reasoning behind the shock decision: "This was an idea that got pitched in the writers room and it sort of caught fire, and we thought it could be a fun way to shake things up.
"As soon as this idea came up, we started talking about what the next couple episodes could be and we got very excited about the way this change wil affect the family dynamics and the characters," he told E! News.
"It seemed more in the realm of a reality that a dog would get hit by a car, than if one of the kids died.
"As much as we love Brian, and as much as everyone loves their pets, we felt it would be more traumatic to lose one of the kids, rather than the family pet."
He added: "It felt like the way that this show was conceived by Seth all those years ago, was this entire family unit including the parents, kids and a dog.
"So by losing Brian, it felt like a void needed to be filled both comically, and also for the interpersonal relationships between all the characters. We felt that we needed to fill that role."
His onscreen replacement Vinny, will add a new dynamic to the series.
"Oh they're very different. Brian was very smart and studious and intellectual, and Vinny is just a lot more of a rough around the edges," Callaghan said.
"Vinny is a really good match for Stewie. Where Brian was sort of a match for Stewie intellectually, Vinny is a good match for Stewie because he doesn't let Stewie get away with any c***. He'll call Stewie out on his B.S. freely."
