The old racing greyhound people had noted decades ago that if they left radios on in the kennel buildings the dog were more relaxed and less stressed. It improved their perfomance overall.
I use this with mine . For the ones I leave at home while I work another, I leave on the radio.
I had noticed with the younger ones if I left the radio off, I sometimes came home to a destroyed house. But same dog if I left the radio on nothing was touched. Interesting. Also there were less footprints and nose prints on the glass of the windows from them peering out too.
Another thing is the radio sounds will screen out the sounds going on outside so the dogs don't react to external noises by barking and gawking as much .
But when the radio is off it is like they are straining to hear every noise and much more vocal.
So at night I have it on very low for them and it seems to make for calm settled more adaptive dogs.
I use chattering talk radio stations, country , old rock and roll, and bluegrass folk music.
Mine dont seem to like the classical so much especially anything with deep bass.
They like voices in there it seems.
Works well on puppies to so they dont seem to feel so alone when they are little babies at night especially.
