I must say that I am no expert, but have a healthy regard for those who understand dog body language. This sounds quite innocuous, but..... I am interested in this context of the stories of "shut down" dogs with harnesses and thunder jackets. On the surface we think they are just "calming the dog", but what is the difference between this and being shut down? How do we know what these collars are really doing to the dogs that wear them? Including the tone and vibrate options.
