Kuvasz Relax Dog AromatherapyDoes Your Kuvasz Freak Out When It Thunders? Of course, your Kuvasz is the most confident, in control dog you've probably ever met. Dogs that were bred to guard livestock against bears, wolves, and cougars are inherently brave. Until fireworks start or a storm rolls in. Then your Kuvasz begins to shake and drool. It's heartbreaking. Just as we have fear triggers such as spiders, snakes, heights, public speaking, and clowns, so do our dogs.
