I saw the Handy Heater (https://www.handyheater.com) advertised (late) last night on TV and am thinking about getting one for our pup. We have a propane furnace but honestly we don't typically bother with it because it burns so doggone much gas and it's just easier to pile on blankets. But it seems like this would have the potential to take the chill off and maybe extend our regular season a little bit. Just wondering if anyone has tried it yet. I've already put our pup under wraps for winter but if we end up getting one I'll report back as to how it works.
