Hudson & Rex

Hudson & Rex is a Canadian police procedural television series based on the Austrian–Italian drama Kommissar Rex. Played by John Reardon, Detective Charlie Hudson is a policeman in the Major Crimes Division of the St. John's Police Department in Newfoundland. Played by Diesel vom Burgimwald and several of his relatives, Hudson's K-9 partner Rex is a German Shepherd dog who is a "highly trained, law enforcement animal" and is not a pet.

The Canadian television series premiered on Citytv on March 25, 2019. Filming began in October 2018 in St. John's, Newfoundland and Labrador.^[3] Season two premiered on September 24, 2019.^[4] In June 2020 it was announced on Breakfast Television that season three would begin production in July 2020, ensuring to work within provincial public health guidelines in respect to the COVID-19 pandemic in Canada.^[5][6] Season three premiered on January 5, 2021.^[7] Season four premiered on October 21, 2021.^[8] Season 5 was released in October 2022.^[9] The popular series made another successful run for season six. Hudson & Rex was renewed for a seventh season on June 12, 2024, which began airing on January 14, 2025.^{[10][11][12][13][14]}

Diesel vom Burgimwald was the original canine star who played Rex in Canada in seasons 1–6, and episodes 1 and 2 of season 7 until his unexpected death in August 2024. His nephews, Dillon and Dante, and a cousin, Dreamer, took over the leading role of Rex starting in season 7, episode 3. German Shepherds Izzy and Iko, also nephews of Diesel, had already been acting as stunt doubles for Rex's action scenes, and will continue to do so in season 8. Reardon did not appear in most of season 7 while he recovered from tonsil cancer. He was replaced by a new detective, Mark Hudson (Luke Roberts), for season 8.^[15][16][17] Reardon would return in season 9.^[18]

Charlie Hudson holds the rank of Detective in the Major Crimes Division of the St. John's Police Department. As a child, Charlie read many mystery novels and had always wanted to be a police detective.^[19] Rex is a German Shepherd, originally in the K9 unit, whose first human partner had been killed while the two were pursuing a kidnapper. Instead of being retired as per the department's standard operating procedure for K9 officers whose human partners have died, Rex underwent an official assessment to determine if he could remain on duty without posing a danger to the public. Rex easily passed the assessment and, after a successful trial period with Charlie, was permanently transferred from the K9 unit to the Major Crimes Division.^[20][21] Since Charlie had never owned a dog, he had to receive some instruction in Rex's handling.

Rex has excellent senses of hearing and smell, allowing him to track suspects and materials (blood, drugs, poisons, etc.) by scent or sound. He can also comfort people in distress and chase down suspects in order to subdue them. These abilities are instrumental in helping Charlie advance the division's investigations, and the two receive further support from Superintendent Joseph Donovan, Forensics Chief Sarah Truong, and IT specialist Jesse Mills in gathering and interpreting evidence. Truong and Mills both become detectives in later seasons.

The first season begins after Charlie has returned to his hometown of St. John's, following a divorce from his unfaithful wife.^[22] The first case is a kidnapping. Most episodes feature different murders, each with unique twists. The background story of the teaming of Charlie and Rex is presented in the season three premiere.

Early in the seventh season, Charlie leaves St. John's in order to search for his brother, who has gone missing in Mexico. Donovan, Sarah, and Jesse look after Rex and work with him until the end of the season, when Mark Hudson – a detective with the Halifax police, and not related to Charlie – is transferred to the SJPD and partnered with Rex.

Diesel vom Burgimwald (Rex) is a 15th generation descendant of Santo, the first German Shepherd to star in Kommissar Rex (Inspector Rex), the Austrian-Italian television series in the 1990s on which Hudson & Rex is based. German Shepherd dogs Is-He (Izzy) and Iko, are nephews of Diesel, and are his stand-ins for some of the stunts. Diesel vom Burgimwald had mobility training before being cast as Rex.^[64] This was Diesel's first show according to his owner-handler Sherri Davis, and training continued on non-shooting days in preparation for future scripts. While on set, Diesel and his co-star-dogs get full star treatment with their own trailers, chef, and chauffeur.^[65] Diesel and his character Rex became an honorary firefighter with the St. John's Regional Fire Department (SJRFD)^[66] during the filming of "Fast Eddie's," which became part of the episode "Flare of the Dog".

While news of his death was released in February 2025, Diesel vom Burgimwald (Rex) died from cancer in August 2024, during the filming of Season 7. His nephews, Dillon and Dante and his distant cousin Dreamer, who were already acting as "stand-ins" for Diesel, succeeded him in the role.^[67] Izzy and Iko continue to perform stunts on the show. Three of Diesel's real life puppies played Buster, Duff, and Kona in "Claws Out" season six, episode six. There are other episodes with several dogs in the story, but his nephews are stunt doubles and stand-ins in action scenes and at photo shoots.^[25] In January 2026, the Toronto Star reported that Diesel and three other dogs were poisoned in October 2022.^[68]

Diesel vom Burgimwald was a Canadian Kennel Club grand champion, and a direct descendant of the Trienzbachtal bloodlines of “German Shepherd Dogs” and related to the dog VA5 Elch vom Trienzbachtal who was the great-grandfather of the original “Rex” (Santo) in the European TV series Inspector Rex on which Hudson & Rex is based.

The Canadian production of Hudson & Rex was produced after getting production rights after the end of the European TV series that was broadcast in Europe for nearly thirty years. Several actors and dog actors played the main characters in Austria and Italy.  The success of Hudson & Rex in English-speaking countries led to a new production in Europe. Kommissar Rex (Inspector Rex) is expected to return to television in Europe in 2026.

Hudson and Rex films at various locations across the City of St. John's, most prominently on the Memorial University of Newfoundland campus. The Bruneau Centre (formerly the Inco Centre) doubles as the headquarters for the fictional St. John's Police Department, while the rest of the campus has been used to portray the equally fictional Heritage University of Newfoundland and Labrador.
