Cute. Apparently border collies are genetically wired to herd.
Long ago I had a pal who had 2 border collies. When you went over to their house, they would try to herd people into this or that room. It was fairly comical. They are very gentle dogs, they don’t jump up and climb on you, they just barely touch you when they are excited. Some of the YT videos from Scotland of BCs herding sheep are just incredible. One dog will gather up 300 sheep and very quickly guide them through a gate.
