Have you ever had a dog before? A husky is an extremely high energy dog; most will need at least an hour of intense exercise per day to actually be happy and not destroy your house. Huskies aren't known for being big barkers either, so if you're looking for a dog that will alert to everything, it's probably not the best choice. My cardigan corgi is 40 lbs and only ~14" at the shoulder, but he sounds like a huge bad ass from behind a door. Just saying you don't necessarily need a big tough dog just to make noise and scare off an intruder. Get a breed that you can live with that suits your family first.
