Mickey Rourke's beloved Chihuahua Loki has died at the age of 18. The Oscar nominee's Chihuahua was one of the dogs memorably thanked by Rourke in his Golden Globe acceptance speech.

"I'd like to thank all my dogs, the ones who are here and the ones who aren't here anymore," The Wrestler star said when accepting his Globe for Best Actor last month.

The pup was prominently photographed walking the red carpet with his master, who called Loki the "love of [his] life," at the Venice Film Festival in September.

The tiny dog was Mickey's constant companion, sitting with him during interviews and accompanying him to red carpet events. Lately he’s been saying: "My dog is very old and she is not going to be around for long so I want to spend every moment with her."

The actor, one of the higher profile comebacks of recent years with Golden Globe and BAFTA wins, told Barbara Walters that his dogs were with him when he was at his lowest. One dog in particular, Lowjack, gave him the will to live.

The 52-year-old actor also told Barbara Walters that his performance as aging professional wrestler Randy "the Ram" Robinson represents the best work of his career. "It's the hardest movie I ever made, and it's the best movie I ever made, with one of the best directors that I ever worked with," Rourke told Walters for an interview to air on her Oscar night special.
