Did that, he didn't care. So who was the one being childish? And what am I supposed to say, "don't let this happen again, or..." what? If I take the dog out, I quite possibly go to jail. I try to be a law abiding citizen, and do not want to abandon my family for jail time.
That is the way the legal system in this country works.
I tried to contact the local authorities, but I had no course of action as long as the dog did no harm. So, I guess that I'm supposed to wait until it rips my daughter's throat out, huh? I guess the jerk had his rights.
Life is stressful - get over it.
Stress is not my problem, I deal with it all of the time. Idiot dog owners do not have the right to willingly cause my stress. So tell me, oh wise one, what was I to do in this situation?
Modify your fence to go into the ground. Then warn the neighbor that if his dog comes into your yard you will be forced to shoot it for the safety of your children. If the threat of it doesn't work at least you will be on the record for warning him, trying to be polite, and being the bigger person, not to mention already contacting authorities who were unwilling to help. The next step you take if he continues to allow his dog to dig into your yard is to take him to court for trespass, and possible intentional infliction of emotional distress (although you wouldn't win on IIOED). If he fails to show up in court, and still allows his dog to dig into your yard - one day let it come through - a place something poison that the dog will eat in your yard. If the dog eats it go to your neighbor's house and tell him "look, I had this - insert item here - in my yard and you once again let your dog dig his way over, and now he is likley going to die if you don't get him attention soon." This way you will look like the good guy once again in that you will save him from his own irresponsibility. Sometimes neighbors are a pain in the ass, and sometimes only extreme measures will work, but believe me if it isn't the dog this person will just do something else.
