Oh Angie I know all too well about problems with fences. You spend thousands of dollars and think you're all set. Ha! Then enter a few neighbors. We've had problems with neighbors dogs on one side of us and behind us. If you recall I had problems with my neighbors grandson (who's now living there) And I too have to sit and wait for my dogs to go out sometimes. In my own yard! And I'm the one who has the fence!
Right now I'm not having much trouble because both dogs are leashed. (yes in a fenced in yard ) Mandy has to stay leashed and Lacey at least until spring because of her leg. And then we'll be back to the same problems!
Sorry I can't add much but it looks like people are giving you some good advice, I hope you can work something out!
