Author W. Bruce Cameron wasn’t planning on writing a series of books about dogs. Instead, he was trying to get his future wife to let another dog into her life.

Wondering if that was going to be a deal-breaker, Cameron, who's had dogs since he was young, decided to tell her a story while they were driving.

“I just made up a story about how her dog would want her to have another puppy and that I really believe we’ll see our true friends again,” said Cameron, author of the recently released "Max's Story: A Dog's Purpose Puppy Tale" (Tor Books 2018; $16.99), acknowledging that when we adopt a canine, we’re setting ourselves up for a very bad day sometime in the future.

“She liked the story so much she not only married me but told me I needed to turn the story into a book,” he said.

The result was "A Dog’s Purpose: A Novel for Humans," which spent 52 weeks on the New York Times bestseller list, became the first in the Dog’s Purpose series and was made into a movie. Currently, Cameron’s "A Dog’s Way Home," another best seller, is being filmed.

Though Cameron writes other novels including a mystery series about a repo man who lives in Michigan (the novelist is from Petoskey, Michigan), which have been well-received, it’s the way he portrays animals that seems to win the most readers from young to old.

Max’s Story features a New York canine cutie, who “adopts” a naïve young woman and shows her how to handle big-city life.

“When I’m writing these puppy tales, I start off with a real challenge for myself — I need to think like a dog would think,” he said.

“Dogs don’t think in words but they know the difference between a ball, chair or tree. I made a mistake in an earlier book when I mentioned a red light. A dog doesn’t see colors. But dogs are very in-tune with feelings — I’ve witnesses that — and for a story to advance you have to show it through what the dog knows and doesn’t know, and how they see the world.”
