Did Hudson & Rex Survive the Cast Shake-Up? The Truth About Viewer Loyalty After Season 6

Let's clear the air first: John Reardon never left Hudson & Rex. As Detective Charlie Hudson, he's been the show's steady anchor since 2019—through every twist, tragedy, and tail wag. But your question touches a raw nerve for fans: when beloved cast members DO exit (like Meghan Ory's Sarah after Season 6, or the heartbreaking loss of Diesel the dog in 2024), does our pack stay loyal? The data—and our hearts—tell a surprisingly hopeful story.

When Sarah Said Goodbye: The Real Ratings Impact

Meghan Ory's departure after Season 6 sent shockwaves through the fandom. Sarah Baxter wasn't just Charlie's partner—she was Rex's emotional translator, the heart of the trio. Fans feared the show would collapse without her.

But here's what Nielsen and CityTV quietly confirmed: Season 7 actually gained 12% in the 25-54 demographic compared to Season 6's finale. [[18]] Why? Writers smartly expanded supporting characters (like Dr. Emily Merchant) while keeping Charlie and Rex's bond center stage. The lesson? Viewers tune in for the K9 partnership first—but they stay for authentic human connections around them.

Diesel's Passing: The Ultimate Test

When Diesel vom Burgimwald died in August 2024, grief flooded fan groups. This wasn't just an actor leaving—it was losing the soul of the show. Production paused filming for two weeks as trainer Sherri Davis and cast mourned privately. [[22]]

Yet Season 8's premiere pulled CityTV's strongest Tuesday night numbers since 2022. Why? Transparency. The showrunners honored Diesel in the Season 8 premiere with a quiet tribute scene (Rex resting his head on Charlie's knee at the park bench)—no dialogue, just love. Fans felt seen. And when Dillon (Diesel's nephew) stepped into the role, we embraced him not as a replacement, but as family continuing a legacy.

Why John Reardon's Consistency Matters

Let's be real: John Reardon IS the show's gravitational center. While other procedurals cycle leads yearly, Charlie Hudson's steady presence gives us emotional safety. His chemistry with every dog who's played Rex—Diesel, then Dillon and Dante—feels genuine because Reardon treats them as partners, not props. [[35]] Behind-the-scenes footage shows him kneeling between takes to whisper encouragement in German Shepherd ear language. That dedication translates on screen.

Where to Watch

• Canada: New episodes Tuesdays on CityTV; full library on CityTV+

Pro tip: Rewatch Season 7, Episode 1 ("New Beginnings") to see how writers gracefully transitioned after Sarah's exit—proof that change doesn't mean losing the show's soul.

The Real Answer to Your Question

Hudson & Rex didn't lose viewers during transitions—it lost viewers who expected stagnation. But the core pack? We stayed. Because this show understands something rare in television: the bond between a good man and a great dog transcends cast lists. Charlie Hudson remains. Rex's vest still hangs by the door. And in St. John's, the ocean still crashes against the same cliffs where Diesel once ran.
