My 2 year old Boston Terrier suddenly developed severe aniexty a year ago and we’ve been using Pet Remedy for the last few months. Smells a bit weird but I only notice it when it’s first plugged in. I would say it does help my dog, it doesn’t make him anxiety- free In the house but it definitely seems to take the edge off and he listens better. I can tell when it needs a refill because he’s more agitated. Would recommend for anxious dogs. Have used the spray and wipes too- also good at calming in a hurry.
