Fans of Chicago Fire are mourning the loss of one of the showâs most cherished cast members â Tuesday, the loyal Dalmatian who became a symbol of warmth and resilience inside Firehouse 51. The beloved dog passed away unexpectedly on May 22, 2022, just days before the Season 10 finale aired.
A Scene-Stealing Companion
Introduced in Season 7, Tuesday quickly became more than just a mascot. With her calm demeanor and affectionate spirit, she added an irreplaceable presence to the intense, high-stakes world of firefighting. Whether lounging by the fire truck or offering quiet comfort during tense moments, Tuesday brought a sense of family and peace to the crew and viewers alike.
The role of Tuesday was played by a real Dalmatian also named Tuesday, trained by Christine Mahaney. Her performance as the station’s pet was subtle but powerful â a four-legged cast member whose silent presence often spoke louder than words.
An Unexpected Goodbye
Tuesdayâs trainer confirmed that the dog passed away due to unforeseen kidney complications, just days before the Season 10 finale aired on May 25, 2022. News of her passing was shared by actor Daniel Kyri, who plays firefighter Darren Ritter on the show. On Instagram, he wrote:
âHeartbroken to learn my little buddy is gone. I got to spend time with her on set & do all the fun stuff, but the real work was done by her trainer. What a good girl she was. Thank you for being part of our family.â
Fans flooded social media with tributes and memories of Tuesday, calling her âthe heart of Firehouse 51â and âa good girl in every way.â
Remembering Tuesdayâs Legacy
Tuesday wasnât just a background figure. She was a comforting presence in the firehouse, often seen sitting by Bodenâs desk or following firefighters around as they prepped for their next call. Her inclusion in the series gave Chicago Fire a sense of real-life camaraderie and community that viewers adored.
In the Season 10 finale, Tuesday made what would be her final appearance, present during the surprise wedding between Stella Kidd and Kelly Severide. She sat peacefully, as if sensing the emotional weight of the moment â a perfect sendoff for a character whoâd always brought light in the darkest times.
A Fan Favorite, Forever
Tuesdayâs death came as a surprise to many, and her absence in the following seasons has been deeply felt. While Chicago Fire has seen many cast changes and dramatic character exits, Tuesdayâs departure struck a unique chord. Her death wasnât scripted or dramatized â it was real, and so was the grief that followed.
As Chicago Fire moves forward into new seasons, Tuesdayâs memory continues to live on â in fan art, rewatch marathons, and the emotional space she filled with quiet loyalty.
She may have only barked a few times, but Tuesday said everything she needed to say just by being there.
Rest in peace, Tuesday.
You were more than a dog â you were family. đ¶â€ïž
