my dog has always been very stressed, and after a recent back injury she was terrible.from the moment i plugged it in she calmed, and has had some long deep sleeps.it certainly works for her!! these are amazing pieces…i am not artistic so my appreciation of the skill is maybe a little over the top but i don’t care…this is just way too cool!!! summer is the perfect time to decorate that patio or deck to do just that. and actually changing- your location, your job, your state of mind, yourself- is harder still.
