Taylor Lautner is mourning the loss of his best friend.
The Twilight actor, 26, revealed Friday that his 13½-year-old dog, Roxy, had passed away.
The Maltese pup has been by the actor’s side for his entire career as she was a gift from his family when he filmed his first ever movie, Lautner said in his a heartbreaking Instagram post announcing Roxy had died.
“Roxy, my family surprised me with you on the set of sharkboy and lavagirl in 2004,” he wrote in the caption. “You have brought so much joy into my life for the past 13 1/2 years. I’ll miss you every day but I’ll take those memories with me everywhere I go. I love you.”
Lautner is a dog lover often posting snaps of pooches that he meets as well as with his ex-girlfriend Billie Lourd‘s dog Tina.
Lautner and Lourd broke up after eight months together in July 2017. A source told PEOPLE at the time the two were “still friendly.”
“She’s really focused on her work right now,” the insider said.
Lautner was later spotted partying at The h.wood Group’s Bootsy Bellows “Red, White and Bootsy” Fourth of July pop up event at Nobu in Malibu without Lourd.
Since the breakup, both stars have been busy with their own projects, Lautner having previously starred in Scream Queens and Lourd reprising her role in Star Wars: The Last Jedi and working on American Horror Story.
