No one has the right to come onto my property no matter what the reason may be. Do you let your neighbors walk in your yard? If your dogs cross the fence call them back or wait. I like the law.
I don't want anyone but myself to have the RIGHT to be on my property. Simple as that...
Your dog gets on my place, either slip in and take the risk of being prosecuted, or come knock on my door an ask to retrieve your dog.
