A dropperful of this oil helps calm my nervous and anxious pup a bit, but isn’t enough to knock him out or make him sleep too soundly. I like that the potency isn’t off the charts but it still helps with his mood/behavior. It does sort of smell, even while the package is still sealed, which is the only reason why I’d knock a star off. Otherwise, the clear and colorless oil intrigues my pup’s tastebuds without any objection.
