My dog always sniffs my knees, then he sits down for a few seconds and then stands up and sniffs my knees again, then sits back down again then up again and sniffs my knees. This can go on for quite some time.
It isn't a recent thing he's done it ever since we've had him. He does it to me and my eldest. Never really noticed him do it to my youngest or my dp.
He mainly does it when we've got bare legs.
It's just always puzzled me to what he's doing. Just wondering if anyone could shed any light?
