When we lived in the Gallatin Valley in Montana, there were cattle drives every spring, moving the dogies out to fresh pastures. Inevitably, some cows would opt for a different pasture en route. But these drives always involved these Australian Blue Heelers, and one dog would calculate where an errant cow would be going and head it off. That cow did not want an encounter with the dog, and would hurry to rejoin the herd. Those dogs could nip!
