I know what you mean. Our dachshund, Valdy, is profoundly affected at some deep level by passing ambulances and police cars with their sirens on. He proceeds to sing along with them dolefully and varies his tone and pitch in ways that are quite uncanny. Sometimes the tone goes up when the pitch goes down...sometimes it's the other way around. Either way, it works its way right to the core of your nervous system and elicits dramatic instinctive responses, like yelling: "Will you shut up?!!"
