Yes, it does. It is a scientifically proven fact that Valerian root has properties that help calm the nerves of humans and other animals. When a dog enjoys a comfortable sleep with mysterious dreams, a sudden noise or a tire blast can cause it to show uncontrolled anxiety and stress.  At such a time, Valerian root powder can help reduce those symptoms to a great extent, and appropriate use for the right amount of time can prove to be immensely helpful to cure various other problems.
