I realize that Corgi's are herders by breed and nature, but is there a way to deter them from trying to herd people? Sassy tends to try and herd people when they come and visit by nipping at their feet (she does not bite) just makes the jesture at their feet. She does it to my feet when there is something she is wanting and I am heading in a different direction. I think it is a game with her but was unsure if I should try and break this behavior? No one seems to mind it. They just stop and pet her and move on.
