    It works!!

    My Great Dane used to tremble when it was raining or thundering. Not any more. She is attentive but doesn’t tremble and try to sit in my lap. She will sit beside me and pay attention but she no longer sticks to me like glue when she hears thunder. Thank you!

    It really works

    My rescue dog has major separation anxiety. After trying prescription meds and other things not working, I seen your ad on Facebook. Decided that I had tried everything else, why not give this a try. In 3 weeks Oakley has made tremendous improvement.

Most notice a difference within a week, but results vary depending on the dog and their stress levels.

Place the diffusers in the rooms where your dog spends the most time, like the living room, kitchen or bedroom.

You pay the subscriber price today, and your kit ships again every 60 days so you never run out. You can pause or cancel anytime.
