The dog's owner announced this week that they'd put him to sleep after enjoying one last day at his favorite place, writing on Instagram, "My precious boy Stewart crossed the rainbow bridge today. We went to the beach (his favorite place) where he frolicked in the surf and then enjoyed a picnic lunch of In & Out burgers. We relaxed in the sun and just enjoyed each other's company. Our veterinarian met us there later, and Stewart went to sleep peacefully in my arms while listening to the sounds of the ocean. He was a one in a million kind of dog, he was my supaah staah."
Cheddar has played a vital role in the Nine-Nine since the first season, including serving as ring-bearer for Jake (Andy Samberg) and Amy's (Melissa Fumero) wedding. Numerous dogs have taken on the role, but Stewart played the part longest. In a 2018 interview with Entertainment Weekly, trainer Michael W. Miliotti pulled back the curtain on Stewart's adorable on-set antics, saying, "He does feed off the energy of the set, so if he does make a mistake and there's a reaction, he will make the mistake over and over again just because he can get the laugh."
Stewart's sister Stella took his place in the role earlier this year.
