Stewart's sister Stella, another popular on-screen pooch, has seemingly taken over the role of Raymond Holt's canine companion on the American police show.
A number of fans have taken to Twitter to express their condolences for the pupper.
"My heart hurts. Stewart, the dog who played Cheddar on Brooklyn Nine-Nine, just passed away yesterday. RIP to the goodest boy there ever was," said one fan.
"I am sadder about the death of the dog that plays Cheddar on Brooklyn Nine-Nine than I have been about the deaths of several people I've known in real life," another person tweeted.
A plethora of "RIP Cheddar" posts have appeared across social media.
Raymond Holt, Commanding Officer of the fictitious 99th precinct of the New York Police Department, owned the Pembroke Welsh Corgi with his husband Kevin on the show.
Stewart was the star of the titular episode ''Cheddar' back in season three.
As Holt would say, he was never just a "common b***h".
