Dog is a poignant and unflinching exploration of PTSD, addiction, and redemption, told through the eyes of an Israeli officer returning from Gaza. Haunted by trauma, he spirals into heroin addiction, finding himself among Tel Aviv's community of misfit junkies-until a stray dog unexpectedly enters his life. What follows is a raw, immersive journey through psychological anguish, fleeting hope, and the search for meaning in the wreckage of war. Beyond its deeply personal narrative, Dog offers a profound examination of PTSD's mechanisms-how extreme stress, moral injury, and the experience of combat rewire the brain, making a return to civilian life nearly impossible. With sharp social critique and emotional depth, the novel sheds light on the invisible wounds of war and those who carry them.
