If she is wailing at the gate, one of us will hear her and go get her. I did it the other day and had to ring Bonnie to tell her where Greta was. Bonnie was looking for her after she had been to the loo ! Greta is FAST ! Yes Bonnie does try and keep the gate closed as she watched Greta wander up the other day and she called her back but the gate was open and Greta set off at a run for the road.... instead of coming up our drive.. Good job Bonnie is fit and can run fast ! The gate is normally kept closed now but it is such a chore if you need to drive down to their house !!!
