Interesting, do you have a place I can read that at. I believe you, but I would like to update my site with the information
I’m just getting that from timing it in the video.
It’s hearing.
That’s how dogs know when a storm is coming. The storm (typically) moves west to east across the midwest plains. It thunders and lightnings all the way as it travels. People can hear the thunder of a storm when it is about 5-8 miles away. Dogs start hearing it at least twice that far away. It stands to reason that a dog’s hearing is superior to humans’ at pinpointing direction and distance of the sound as well. So I’m sure they can tell which storms are coming directly at them and which ones are going to pass by to the north or the south.
If you live in a secluded place where there are no noises for miles and miles around, you will notice that a dog will get quiet with nervous ears first(like he does when there’s a squirrel on the roof or a mouse in the wall or something like that), then about fifteen to thirty seconds before you can just barely hear a far off storm, the dog will already be in full panic, or maybe 3/4 panic mode.
The fact that a dog seems to do this just as well in a noisy city seem to indicate to me that a dog’s ears are also superior to humans’ in one other aspect:
noise filtering.
