The Walking Dead family is mourning the death of Seven, the canine cast member that played Daryl's sidekick, Dog, on the zombie-apocalypse drama.
The show's representatives also shared a photo gallery of Seven living his best life on the set.
His breed and age were not disclosed.
"Rest in peace, Seven. #TWD's best boy," it was captioned.
Norman Reedus, who played Daryl, posted on his Instagram Story: "Gonna miss u seven. Best tv buddy ever," alongside a broken heart emoji.The dog joined the ensemble in Season 9 and appeared until the show wrapped with Season 11 in 2022.
Reedus told ComicBook.com in 2018 how happy he was to be working with Seven.
"I think he's the smartest cast member we got," he added. "We just did a scene the other day that ended up being the opposite of what it was supposed to be because the dog just wanted to do something else, and it came out so much better. He'll probably be running the show. It's great! I love it. He loves me, too."
