Dog is a poignant exploration of PTSD, addiction, and redemption, told through an Israeli officer returning from service. Haunted by trauma, he descends into heroin addiction among Tel Aviv's marginalised drug community-until a stray dog unexpectedly enters his life. The novel traces a journey through psychological anguish, fragile hope, and the search for meaning after war. Dog examines how extreme stress, moral injury, and combat make civilian life elusive, along with the healing power of an unexpected human-animal connection.
