It's geting OLD

[Tink]

I have a neighbor who lives less than a mile away with an intact male lab. He's decided my house is where the action is so is determined to be here rather than home. I've caught him and called them to pick him up 4 times so far... He's a very friendly dog, a nice looking lab... but I don't need him here riling my dogs up every couple days.

I could call my township board members and have the dog impounded and the owner fined, but that's not a great way to stay on friendly terms with neighbors. The dog wears a collar that's supposed to shock him when he gets out of a certain range of the transmitter... obviously it's not doing the job.

Any ideas to solve this problem without making enemies?
