Hello my fellow corgi people, just wondering if anyone has heard of or used "calming collars". Got home from work today and my wife suggested we try them for our somewhat anxious beagle ( separation anxiety), and my occasionally " hyper" Benson.they are apparently filled with calming herbs etc. a natural aromatherapy if you will. Kinda wondering if this is just another gimmick or if it actually helps, of course their website exudes the positive value of the product,but I prefer to hear testimonials from reliable sources , like yourselves, so any input would be appreciated, thoughts? Thanks!
