“Dogs don't understand nightmares. Dogs don't understand trauma or memory or the particular cruelty of a brain that stores the worst things in the highest-resolution format and replays them at three AM with surround sound. But dogs understand distress. They understand the change in breathing, the shift in the body's chemistry, the way fear smells different from sleep. And Moti, who was not a therapy dog or a service dog or any kind of official dog but was simply a dog who loved her person, understood that her person was afraid.”
