So far he has stayed in the fence now that we have put up a new gate. Last time he got out which was over the weekend, he decided to push the gate open while we were in the fence and I was watching his actions. He had looked over at the cow pasture and made a quick get away out of the fence over to the cow pasture next door.
We have watched him the last few nights before sunset and we watch him some during the day while we work as our windows overlook the pasture. He starts getting wild eyed and wants out when the dogs down in the valley start barking at night/early morning. I think he wants to be down with the herd of dogs so that he can patrol with them as he can see part of their pasture which has the sheep in it. Anyways, when he started acting like he was measuring up the fence we kept telling him no and he snaps out of it. We got two puppies and are hoping they will all three grow into a nice pack. We will be adding more fencing as time goes on and may end up getting some more livestock as it probably is companionship and boredom mixed together.
Thanks so much for all the feedback!
