When my senior Rescue was diagnosed with Cushings he was often restless at night..Sleep deprivation nearly killed me. I bought the plug-in and despite it’s slightly farmyard smell I was happy to have the product. Eventually my boy settled. I just use the spray now and then (on his bedding) when he is struggling with his condition-as I did last night and it worked a treat……Funny story..When I first used the plug in, my other little dog slept for about three days, so calm was she…
