Amanda Seyfried says she doesn’t know how she would have navigated Hollywood without rescue dog Finn

The actress’ Australian shepherd just celebrated his 15th birthday in September

Amanda Seyfried gets by with a little help from her furry friend.

In an exclusive conversation with PEOPLE, the actress, 38, opens up about how her rescue dog Finn changed her life for the better.

“[Pets give us] purpose. No matter what we say, we can’t deny the fact that we need purpose, and to have that responsibility of taking care of animals,

who don’t have a voice and can’t really do much for themselves, it gives you so much more than we could ever give them, really,” Seyfried says.

“I don’t know what my twenties would’ve looked like without Finn. I really don’t know,” continues the Mamma Mia! star, who recently partnered with Synchrony’s CareCredit and Pets Best insurance.

“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.”

Seyfried adopted her 15-year-old Australian shepherd while working on the set of the HBO series Big Love.
