The viewed print, which was incomplete and had no production credits, ran approximately 45 minutes. The cast and production credits were taken from copyright records, as well as the 31 Oct 1925 Variety review and the 14 November 1925 listing in Motion Picture News. According to Variety, when the film played in New York City, it had a running time of approximately 70 minutes.

 On 27 May 1925, Variety announced that actor George Hackathorne had been cast in a lead role in His Master’s Voice, which was being produced at the Hollywood Studios by director Renaud Hoffman for the Lumas Film Corporation and Gotham Productions; a news item in the 7 June 1925 Film Daily stated that filming was set to begin in the near future. An article in the 6 June 1925 Motion Picture News mentioned another film with the same title from Independent Pictures Corporation, written by Adele Buffington and featuring a dog named Lightnin’, but several weeks later the 27 June 1925 Motion Picture News noted that the title had been abandoned by Independent, since Lumas was ready to release their own His Master’s Voice with Thunder, the Marvel Dog. An advertisement in the 26 July 1925 Film Daily, which included an image of Thunder and proclaimed “ready now,” stated that His Master’s Voice was the fourth release of “this season’s Gotham Twelve,” referring to other films to be released from the company. By 1 August 1925, Exhibitors Trade Review reported that prints and negatives for His Master’s Voice (“the first of the new photoplays featuring ‘Thunder,’ the Marvel Dog”) were on their way to the East Coast for distribution. Two weeks later, the 15 August 1925 edition of Exhibitors Trade Review confirmed that the film had arrived in New York, and had already been screened to initial acclaim. Also mentioned was that the author of the original story, Frank Foster Davis, was Thunder’s owner, and that Thunder’s “pedigreed registered name” was Beneur Tillo von Riedekenberg. The film reportedly marked the screen debut of “Mrs. Thunder,” a white dog named White Fawn, as well as the first appearance of Thunder, Jr. Although the picture was “scheduled for immediate release,” it was not widely distributed until October 1925.

 In 1932, an edited version of the picture, which was retitled The War Dog, was approved for exhibition in New York by the New York State Censor Board. The 1932 version, for which no reviews have been located, appears to have incorporated large portions of the 1925 silent film, with some sound sequences added. Although the plot remained essentially the same, the character names in the 1932 film were different. Also, Thunder is billed as the canine star of His Master's Voice, whereas the dog's credit in The War Dog is "Rex."

 This film is extant. Prints are located at the BFI National Archive in London and at the Library of Congress in Washington, DC.
