RE: shock collar????????question
I think you need to rethink what you plan to do. Dogs don't think the way we do. With dogs, it's all about association. A dog wearing a ecollar for the first time and gets shocked won't know why or how.
Personally, I feel everydog should be confined somewhat to either a yard, kennel, etc. A dog should not be let loose even in rural areas unsupervised.
One solution, work out your differences with your neighbor. Another, look at underground containment systems.
