This isn't hope. This is neuroscience. When a dog engages in repetitive licking, their brain releases serotonin and dopamine. The same chemicals responsible for calm, happiness and emotional regulation.
It also directly suppresses cortisol - the stress hormone driving every bark, every howl and every act of destruction. This isn't managing anxiety. This is your dog's own brain chemistry doing what it was always designed to do.
The calm you've been desperately searching for isn't out of reach, it's already inside your dog waiting to be activated.
