I've tried to talk Trinity into getting the voles to relocate, but she is not interested. Her priority is to chase off any bird that has the audacity to land on the property. When she was a puppy, a sparrow flew by, and she snapped it out of the air - apparently God's eye was not on that sparrow. Susan puts up birdfeeders in the fall and when the birds swoop in to feed, Trinity sprints and lunges at them. No leisurely resting at these feeders; it really is survival of the fittest. Maybe it's bad karma, but I don't mind because that dog is saving me cash on bird food.
