The K-9 Companions series is a multi-author inspirational romance line from Love Inspired featuring stories where dogs bring people together. Deb Kastner launched the series with Their Unbreakable Bond (2021), in which a rodeo cowboy recovering from an accident trains avalanche rescue dogs alongside his best friend’s sister. The series has grown to include dozens of entries by various Love Inspired authors.
Each book pairs a romantic storyline with a canine companion who plays a meaningful role in the plot. The dogs range from trained service animals and therapy dogs to rescue animals and K-9 partners. Settings span from Colorado ranches to Alaskan towns, and the stories share common themes of healing, trust, and faith. Kastner remains a frequent contributor to the series, with entries spanning its entire run from 2021 through 2026.
