        Too soon to see any change

        Accepted Calming supplement as a Reward as being an Omni Customer. Already have Omni Plug in Calming Diffuser so willingly thought support it with an everyday supplement. I have a 3yr old miniature JRT, she's full of energy & barks at specific triggers. Too soon to see if anything helps with added on supplement & reducing the barking, I'm waiting for Nov 5th because last year she really struggled & was previously not frightened by the fireworks so, I'm hoping diffuser & supplements will have a positive reaction & make a difference.
