Amanda Seyfried is grieving the death of Finn, her beloved Australian shepherd, who died at age 16. On Saturday, June 25, the 40-year-old actress shared a selfie with Finn on Instagram and captioned the tribute, “This one’s forever and ever.” Finn’s loss also prompted a tender response from Olivia Munn , who commented with a message honoring the dog. Seyfried adopted Finn while filming HBO’s Big Love , the series that ran from 2006 through 2011. Finn Was Seyfried’s Hollywood Constant In a 2019 interview with People , Amanda Seyfried said Finn changed her life almost immediately. The actress explained that her unpredictable early career made stability difficult, while Finn gave her a reason to come home and helped her build a sense of solitude and independence. Seyfried later said in 2024 that caring for animals gave her purpose and helped keep her grounded while navigating Hollywood. Amanda Seyfried has also arranged film contracts so Finn could join her on set when travel was manageable, and she has built an animal-friendly life at her Catskill Mountains farm with her husband, Thomas Sadoski , and their two children.
