On another forum I know someone posted about it and they said it worked wonders. You can check out a clip of what sort of programming they have on the website, but he said that his separation anxiety hyper huskies calmed down after just about a week of it...
So I suppose take that for what you will. Before I brought Talos home, I investigated it a bit, but I'm not sure. It seems well researched and if it actually works to help socialize and calm dogs, then totally worth it for people like me who have to leave my pup alone during the day.
