Amanda Seyfried is mourning the loss of a treasured family member.

The Housemaid star shared that her beloved dog Finn has died at the age of 16 in a touching social media tribute.

As she captioned a July 24 Instagram post featuring a selfie with Finn, “This one’s forever and ever.”

The 40-year-old also shared photos from a few of her favorite memories with her furry friend.

In one snap shared to Instagram Stories July 24, Seyfried enjoys a stroll on the beach as Finn playfully leaps in the air beside her.

In another, the Mean Girls alum lies on her back beside Finn with her arms and legs up to mimic his position.

Meanwhile, in a separate pic, Seyfried and Finn can be seen cuddling up with their mouths open. And there are plenty more memories where that came from. As she wrote over the photo, “I’m gonna keep ’em comin’.”

And Seyfried wasn’t the only celeb who recognized Finn as the goodest boy. After all, Olivia Munn was just one star who sent her condolences under Seyfried’s post.

As she wrote alongside red heart emojis, “Fly high, sweet pup.”

Meanwhile, Rachel Brosnahan also sent Seyfried some support.

“Big hug hug,” The Marvelous Mrs. Maisel star wrote. “They’re forever family.”

Seyfried adopted the Australian shepherd while working on the set of the HBO series Big Love.

“As soon as he was mine, like 24 hours after I got him, I realized something about me needed him,” she told People in 2019. “He completely changed my life and helped me find my solitude and my independence.”

Earlier this year, the Dear John actress—mom to Nina, 9, and Thomas, 5, with husband Thomas Sadoski—celebrated Finn’s 16th birthday.

“My sweet boy has stuck with me for the sweetest 16 years and counting,” she captioned the September 2025 Instagram post featuring a photo of her pup in a birthday crown. “Finn’s brought all the love, warmth and total presence a girl could only dream of…”

And as Seyfried climbed the ranks of Hollywood, Finn proved time and again he was woman’s best friend.

“I don’t know what my twenties would’ve looked like without Finn. I really don’t know,” she told People in 2024. “I don’t know how I would’ve navigated Hollywood. I mean, I stayed out of a lot of trouble, I think, because I had that guy to come home to.”
