This is something that Asha does occasionally, but especially with certain conditions. The main one being a recent heavy rain and a breeze. It must bring out smells that are newly released and you can see the wheels churning in her head, reading the all the news that's just been released.
We got caught in the rain today on our hike, we were soaking wet and cold. Half the sky was still blue, but I had to stop and video a few seconds of this. She had to stop to smell the wind several times once the rain passed. She slobbers freely when her brain is processing odors, plus she's soaking wet and muddy. I know what the action of this is regarding nose to brain, but I can't remember what it's called. Do any of you see your dogs do this "in the wild"? ((It's not anything they would do in scent work sports))
