Why does your male dog howl loudly when he hears a police or firetruck siren?

Either it is hurting his ears or he is merely joining in to what he thinks are other dogs howling. Kinda like wolves and coyotes do, it's still instinctive to a domestic dog.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
