Here's a question for anyone with greater knowledge of canine psychology than I: why do dogs howl?
The neighbouring household (in its madness and degeneracy) has acquired a collection of four or five small yapping dogs. Other than the yapping, which at irregular intervals takes place for ten minutes at a time, they have a vocal ritual of sorts where at least once a day they share a howling chorus. It occurs to me that I don't actually know why they do it. The obvious answer "to annoy Deranged Nasat" is tempting but probably inaccurate.
So, can anyone enlighten me - is it to strengthen social bonds, affirm a pack identity, communicate that status to others as a advert of collective strength, all of the above?

I'm assuming the siren was close enough to a howl that your dog took it for such and was responding in kind as a means of establishing communication. Was it simply a "yes I'm here", getting a shared network going like a canine form of facebook, so everyone knows who is where and how many there are, or was it a response to a perceived challenge, "this is my territory, I can match you in strength, be on your way"? If dogs respond to other howls, why does the first dog howl? Again, curious or threatening or scared? Preemptive "tough guy" behaviour, the dog equivalent of a "hawk"?
