Loki, my dog, will follow your cursor around the farm. He can go through fences.
The sheep will wander about the paddocks and will sometimes go through a gate. Sheep can not go through fences.
The sheep don't get on well with Loki so will move away from him if he gets too close.
Try using Loki to move the sheep about. Can you get them all rounded up in one paddock?
Cick anywhere in this box to close it.
