Casting the top dog in a film that also stars Jai Courtney, Jack Thompson, Deborah Mailman, Matt Day and Celeste Barber was a challenge.

“We made it a point of focus for our casting department to rescue and adopt a dog and rehome them,” Silvey says. “We thought it was a really important example to set.

“It took a long time to scour the nation. Our amazing animal department looked everywhere and found Squid in regional Victoria.”

Animal trainer Rebecca Faulkner says they started the search in dog rescue groups.

“We knew from the book that the dog had to be a particular size to work with a young child,” she says. “And had to be, as Craig wrote in the book, this indiscriminate, one-of-a-kind terrier.

“And it was hard because the dogs that are in rescue are often bully breeds or oodles so you don’t see them very often.”

Opening her emails one morning, Faulkner saw Squid’s face with the message “this dog is ready for adoption” from a foster home in Geelong.

“I was like ‘there she is. I hope she’s confident, I hope she’s food-motivated’,” she says. “I arranged to meet her right away and as soon as I saw her, I thought, ‘yep, that’s the one’.”

Faulkner quickly realised why Squid, who was about a year old at the time, was onto her fourth home.

“She’s a terrier through and through,” she says. “She’s busy, she’s smart, she picks things up very quickly. She’s got long legs and she can jump a fence like it’s not even there.

“So Squid needed a home that was busy, could occupy her mind and also give her the ability to relax. She needed to be able to calm herself.”

Faulkner says Squid proved very trainable at racing agility courses, taking direction and just being comfortable on a busy film set.

“I’m sure that dog is smarter than me,” she says. “Lily and Squid worked incredibly hard on this film. They were on set almost every day, all day. They’re 10-hour days.”

Faulkner, who has also trained dogs with business partner Peta Clarke for the TV series The Lost Flowers of Alice Hart and the horror film Sting, thinks they are so common on screen because they live in so many Australian homes.

“If I’m watching a film or a TV show and the family doesn’t have a dog or a cat, I think it can be missing something,” she says. “Animals can bring such a strong emotion to a film. A dog can really bring an emotional poignancy to a scene if it’s done well.”

After finishing the film, Squid is now part of Faulkner’s family in Daylesford in rural Victoria - joining two other dogs, three cats and some chickens.

“She’s a real-life rags-to-riches story,” she says. “She waltzed in, jumped up on the sofa next to my beautiful old dog Teddy and she was just oozing ‘I live here now’. She just brought the whole family together.”
