Dog Awesomely Sings The Blues [Video]

This dog has obviously had hard times. Cause he sings the blues hilariously, and awesomely! It doesn't quite sound like it's coming from a dog!

According to the OP, this pup, named Coyote, is hitting a Bb note. How do you train your dog to not only hit, but hold a certain note?? I can't even teach my dog to sit on a consistent basis.
