Do you think this is interesting?

Well, first of all, what seems to be going on is your really putting all of the effort to explaining the sound. What you should do, is give perhaps 3 sentences MAX to describe the howl, then continue on with the story line, otherwise things start to sound more unorganized. Second of all, try to use more varies of words. For example, instead of using the word "howl" all the time, use words such as "cry", "sound","shout", "banter", "yelp", "wail", "holler", and "wail". There are still quite a few variations of "howl" out there. Also, try not to start so many sentences with 'the', if you mix it up a little, it will be more interesting and will have some flow to the entry. Hope that this helps! And it does still sound very interesting! Good luck! :)
