To keep her safe, and stop her going near our road, which is a main thoroughfare
with cars trucks and motorbikes constantly speeding past. The collar is electronic
and sends out a warning signal each time Flossie gets within a couple of metres of
the fenceline. If she ignores the warning and goes closer, it gives her a slight
shock. No worry about that, she keeps very close to the house since she's had
this collar around her neck!
