We are looking into this as a way to calm barking, but I am not sure how it will help- anyone use it for that? (we live in an apartment building and our landlord has gotten complaints of one of our guys sort of howling during the day when we aren't home- he does it though when he sees things outside. How our brilliant landlord did our front windows- you can't get curtains to hang all the way to the ground! he installed the curtain rods all the way at the top of floor to ceiling windows and there is a good 3 feet at the bottom that don't get covered).
