Is Rex on Hudson and Rex a Real Police Dog? | The Real Story

Rex feels real because the show is built around a believable working-dog partnership. He tracks scent, guards scenes, reacts to danger, and often spots the clue that humans miss. That is the hook of Hudson & Rex: the dog isn’t just a cute sidekick.

On screen, Rex is a police K9 working with Detective Charlie Hudson in St. John’s. Off screen, the original Rex was Diesel vom Burgimwald, a trained German shepherd actor handled by Canadian dog master Sherri Davis. Later episodes use Diesel’s relatives to carry the role after his death.

So the clean answer has two parts: Rex is written as a police dog in the series, but the dogs playing him are screen performers. Their work comes from training, handler cues, editing, camera angles, and a crew that makes canine action read clearly on TV.

Rex On Hudson And Rex: Real Police Dog Signals And Set Facts

The confusion makes sense because the show doesn’t treat Rex like a normal family pet. He rides with detectives, searches crime scenes, reacts to suspects, and seems to understand far more than a regular dog would. The official U.S. show page describes Rex as Detective Charlie Hudson’s German shepherd partner in a family police drama set in St. John’s, Newfoundland. The UPtv Hudson & Rex page keeps that show premise clear.

That wording belongs to the fictional story. It doesn’t mean the animal actor is employed by a real police unit, certified for patrol work, or sent to real calls. Screen dogs can be trained to act like working dogs without holding a law-enforcement job.

Who Plays Rex?

Diesel vom Burgimwald became the face of Rex because he had the look, nerve, and handler bond the show needed. His expressions sold the role: tilted ears, steady eyes, and that sharp little pause before action.

Production material from Pope Productions names Rex as a former-K9 German shepherd in the story and lists Diesel vom Burgimwald with the part. The Pope Productions synopsis is useful because it separates the character setup from the real performer behind the role.

After Diesel’s death, the show did not replace Rex with an unrelated random dog. Reporting from The Canadian Press said Diesel’s nephews Dillon and Dante had already been training for the role, while other related dogs handled stunt work. That family link helped the show keep a similar face and body shape on screen.

Why Rex Looks Like A Real Working Dog

A TV dog has to hit marks, repeat action, and stay calm around lights, crew, props, vehicles, and actors. That is a different job from patrol work, but it still takes discipline. A dog who breaks scene, stares at the handler too long, or wanders out of frame can ruin a take.

The magic comes from many small pieces:

• Handler cues that tell the dog where to go and when to react.
• Short action beats stitched into one smooth scene.
• Camera placement that makes the dog’s glance feel like a clue.
• Sound design that adds tension to sniffing, running, and barking.
• Editing that pairs Rex’s reaction with a human find.

That mix creates the illusion of a police partner who understands the case. The dog may be responding to a cue, but the scene makes Rex feel alert and aware.

How The Show Makes Rex Feel Authentic

The series gives Rex jobs that match what viewers expect from a working shepherd. He searches rooms, follows scent trails, warns Charlie, and pressures suspects without turning each scene into a stunt. That restraint helps. Rex often wins a moment through timing instead of noise.

Question Fans Ask	What Is True	Why It Matters
Is Rex a real police dog?	Rex is a fictional police K9.	The police work belongs to the story.
Was Diesel a real dog?	Yes, Diesel vom Burgimwald was a German shepherd actor.	The role was played by a live dog, not only effects.
Did Diesel work for police?	Public show material identifies him as a performer, not an active police dog.	That keeps the actor and character separate.
Who trained Rex?	Sherri Davis led the dog work for the series.	Her cues and planning shaped Rex’s scenes.
Are there stunt dogs?	Yes, multiple dogs help create action scenes.	Harder moves can be shared between trained dogs.
Why does Rex act so smart?	Training, timing, editing, and actor reactions sell the idea.	The scene builds meaning around the dog’s behavior.
Did new dogs take over?	Yes, Diesel’s relatives continued the role after he died.	The show kept the Rex look and style close.
Is the character based on a real K9?	The series follows a fictional police setup inspired by canine crime dramas.	The cases are scripted for TV pacing.

Actors around him matter too. John Reardon and the rest of the cast react as if Rex is a trusted teammate. When the humans pause for Rex, praise him, or change direction because of him, viewers accept his role in the case. A dog’s action feels smarter when the human cast treats it with weight.

There is also a smart limit to what Rex does. He finds scent, objects, movement, and danger. Then the detectives connect those pieces. That balance keeps the character fun without making the show feel silly.

What Changed After Diesel?

Diesel died during production of Season 7 after cancer, according to reporting based on statements from the show team. CityNews, carrying The Canadian Press report, said Diesel was eight and that his nephews had taken over the role. The CityNews report on Diesel also notes that several dogs were used to create each episode’s feats.

That matters for viewers asking why Rex may feel different in later episodes. A new dog can match the role, but no two dogs have the same rhythm. Ear carriage, stride, stare, and handler bond all show on camera. Diesel had a calm, dry wit in his face. Dillon and Dante carry the part, but careful viewers may spot changes.

The show’s choice to use relatives was smart for continuity. Dogs from the same line can share build and expression. With training, they can also learn the same marks and cues. That doesn’t erase Diesel’s screen presence, but it keeps Rex in the story with care.

Screen Clue	What You’re Seeing	Viewer Takeaway
Rex stares at evidence	A trained pause near a prop	The edit turns the pause into a clue.
Rex barks at a suspect	A cue paired with actor movement	The scene makes the bark feel like judgment.
Rex tracks scent	A staged route with reward cues	It mirrors K9 work in a TV-friendly way.
Rex protects Charlie	Choreography with safe spacing	The bond looks tense but controlled.
Rex finds a person	A trained find behavior	The payoff gives Rex agency in the plot.

So, Is Rex More Actor Or Officer?

Rex is both, depending on the side of the screen. In the story, he is a police K9 with a badge-like role beside Charlie. In real life, Rex is a character built through animal acting and careful production.

That answer doesn’t make the dog less impressive. It may make the performance better. Police dogs train for real tasks under real pressure. Screen dogs train for repeatable action under set rules. Both need control, trust, and a strong handler bond, but the jobs differ.

If you came here wondering whether Rex was pulled from a police unit, the answer is no based on public show material. If you meant whether Rex is played by a real German shepherd doing real trained behaviors, yes. Diesel and the later dogs were real performers whose work gave the show warmth.

What Fans Should Know Before Rewatching

Watch Rex’s scenes with the craft in mind, and the show gets richer. Notice how often the camera cuts from Rex’s eyes to a clue. Notice how Charlie’s reaction gives Rex’s behavior meaning. Notice how a sit, stare, or head turn can land like dialogue.

That is why the character works. Rex is not a real officer outside the show, but he is not a prop either. He is the center of the series’ appeal: a trained dog actor playing a fictional K9 so well that the line feels blurry. That blur is the point, and it’s why fans still ask the question.
