I agree that many dogs are afraid of storms because their hearing is more sensitive than than that of humans. In particular, our pit bull named Sheena always panics when the rain is pouring and thunders are just raging every minute. She would run all over the house, going under tables, huddling next to us. It's really sad when I see her acting like this. We always do our best to comfort her, but to no avail. One time, there was a really bad thunderstorm. Sheena came running into the house, and she almost hit my 80-year-old grandmother. Thank goodness my grandmother wasn't hurt. Though she was safe, one of the flower vases on the table got hit by the running Sheena. Oh well, we just thought that at least the vase can be replaced.
