I've never had a fence, so Star has never been exposed to having things on the other side of one, or having a clearly defined, permanent boundary. He's started running up and down the fence barking at anything and everything, charging the fence, and really guarding the yard.
The guy who does the yard, I didn't even know there was one, came the other day and said that Star wouldn't let him near the fence. Apparently the first time he had no trouble at all. I'm obviously going to put the dogs up for him, but I'm a little worried about people passing by.
Is there a way to teach Star that the fence doesn't have to be that imposing force that he has to guard so much? Like Penelope, she will lie at the fence and recognize the difference between a threat and a passerby. Lucky and Boomer just chill in the sun.
