Uggie, the canine star of the Oscar-winning silent movie The Artist, has lost his battle with prostate cancer.
The famous Jack Russell Terrier was put down on Friday in Los Angeles after his condition deteriorated, says his owner, animal trainer Omar Von Mueller.
He told TMZ.com that it was a "difficult decision" to say goodbye to his 13-year-old pooch who became a movie sensation in 2011 after sharing the screen with French actor Jean Dujardin.
The Artist won five Oscars, including Best Picture and Best Director.
Uggie won a number of accolades for his role, including the Golden Collar Award and the Palm Dog Award at the Cannes Film Festival in France.
The dog was even honoured with a pawprint ceremony outside the historic Grauman's Chinese Theatre in Hollywood.
Uggie, who also starred in Water For Elephants, retired from acting in 2012.
