My brother's dog is afraid of everything. He's a 60-pound pitbull who suffered trauma in his first weeks of life, but has since been well-cared for in a loving family home. Unfortunately, he is still scared of everything - and I do mean everything. He is afraid of people, yes, but also leaves, pencils, water glasses, furniture, and just about any other object you can imagine. Nobody teases or threatens this dog. Has anyone had success calming a dog with a high level of constant stress?
