Thunderstorms

So.. last night. In the middle of the night... I end up with both Willow and Tanner sitting on top of me in bed. Why?? you may ask.. There was a thunderstorm. Not a bad one.. but rumbling. Both dogs, both neurotic dogs, jumped up on top of me and drooled and panted in my face for a half an hour. OMG>> What the heck is going on? They are nuts...
