A few months ago, when I was out of the house a lot attending to my ailing father, I bought a CD geared towards calming dogs and relaxing them. Yogi was just a year old and I thought this might help him. Once I listened to it I realized I already had a lot of this type of music in our music collection of CDs, so I created mp3s and transferred them to an ancient unused phone of mine, a HTC EVO, after wiping the SD card clean. I renamed the phone Dog Phone, and I'm bluetoothing it through a Jambox. It's great and even I am relaxed listening to it! I forgot how calming this music really is- lots of acoustical piano.
