Soothing Pets with Vocal Music!

Have you ever tried music with vocals to soothe your pet? My doggie Chevette used to have terrible separation anxiety. Now when I leave the house I put on my lullaby CD and it seems to keep her calm. I also use lavender oil. Have you tried music for your own doggies? What has been your experience? What kind of music do they respond to? I would love to have your comments on All About Voice FB page.
