Commercial Breaks & Beats

Hi, I am desperate to find out whether a song on a dog food ad is a real song, and what it is. The ad is for sum sort of chewey dog food.The owner and the dog sit in the car, both chewing, checking out the girls. Later the owner puts his elbow out the window, and so does the dog. It`s a real funky piece of music, would love to have it.
