It works wonders when you are travelling with puppy or need you pet to calm down in a new environment. I rub a little under his chin and spray a bit on the blanket and little soft toy. Seems to relax him and calms him down. I personally hate the smell. But my puppy seems to love it. Another thing is that it’s a bit bulky to carry and leak so I transfer some in a little travel size spay bottle. Don’t go any where new without it.
