I do not mean to bring you down - by no means - but the real wolves do howl in response to other howling - not to any sights - even as beautiful and magical as yours !! LOL
I know it for sure because my Boris the Tiger is a completely wild wolf - tamed only so far as to please some humans ...
I myself do love full moon and would howl willingly but this dog would think I am crazy ! LOL
