Get a rope.
No reason?
Yup. I am glad my neighbors are so afraid of my dogs that they won't even come near the fence, much less get in my yard. I always worry about anti-freeze, though, as I have a dog that would rather drink out of mud puddles in the driveway than his water bowl, which always worries me. Not sure what the attraction is...does anyone else know?
A rope is a bit severe. Give Dad a baseball bat and two minutes of privacy with Mr. Neal.
