what does howling mean?

I think it might hurt their ears. Where I live, they test tornado sirens every
Friday at 11:00am and I've noticed that my dogs will howl if they happen to be outside when they go off.

My babies howl when they here a siren too.
I guess its common, maybe it does hurt there ears.

This subject has come up before on Pet Talk. The sirens do not hurt the dogs ears. The dogs think they're communicating with other dogs (that happen to have 4 wheels and a ladder). Fenway does this all of the time (twice this weekend). It makes me laugh and it makes my neighbors laugh. I've actually had people stop their cars to make a comment and laugh.

I just wish I knew what he was saying to them!
