Justin Theroux and Jennifer Aniston are mourning the death of their dog, Dolly.
Theroux took to Instagram on Monday to announce the pet's passing.
"Tonight, at sunset, after a heroic struggle...our most loyal family member and protector, Dolly A. laid down her sword and shield," he wrote alongside a few snapshots of his four-legged friend. "She was surrounded by her entire family."
Quoting a few words from George Graham Vest, Theroux then wrote, "The one that never deserts, the one that never proves ungrateful... is the dog-- faithful and true, even in death." He ended his post by writing "Rest in Peace Dolly" along with the hashtags #AdoptDontShop and #RescueDog."
In one image, two hands grasped each other’s — one presumably Theroux’s while the other appearing to be of Aniston, 50. In the last photograph, they wrapped the late pup in a soft blanket.
Theroux shared Dolly with his now-ex. In fact, the "Friends"actress actually named the beloved pet after Dolly Parton.
"I'm very touched when people have known me so long or to say that I've been an inspiration, but you really know when you've got a true fan when someone like Jennifer Aniston says, 'I named my dog Dolly Parton,'" Parton told E! News in 2017. "She's got a dog, and I said, 'Is that a compliment?'"
