We built this fence to keep the dogs in and there was never an issue then one day Teddy was out playing with Amelia when he was put away. Sure it was a mistake we put him back and carried on and again it happened. Upon investigating we watched the cctv and saw this little rascal teaching him how to get out! We asked her to show us what she was doing and she repeated it. Needless to say that is why you see the fence looking different now as we doubled up all the runs to contain this furry ferret! Teddy slinks out looking al sheepish but inside he's proud of himself!
