I would be mad too. Hopefully this underground fence thing works. We have a neighbor dog, but he only comes over once in a while, but he always goes home right away. He only comes over if I get dropped off in the driveway or something. Once he came at the end of the driveway, and I told him to "Go Home." then he ran across the street, and he was soooo close to being hit, it looked like his flying tail touched the car!
I hope this works for you anna.
Good luck!
