Dogs takes human life and translates it to a dogs life. So that you can then listen and realize your life is much like a dog. You are an animal of the machine. Our actions and character is not far removed from that of a pack animal. Fight to the top and someday the top will overcome you. It's all a game, you work your way up, but don't get lazy, to be on top you have to be aware because someone is always trying to best you. You begin to believe no-one is really a friend it's all just face time. Loyalty becomes a trinket to you. You've become a cog of the machine. Your opulence takes it's toll on you and in the end you are also a victim of the machine. The guitar work in this song is insane, it makes the entire piece come alive both human and animal. It melds the to realities. David Gilmore is one of the greatest at his art.
