Hi Eleanor,
I come from the land of fences in Louisiana. Down there in the NO area, the houses are mainly on lots and all have some type of fencing. When we bought our house in VA, we were moving up with three dogs and I was a nervous wreck. I was sure that my dogs would all get lost in the woods.
Where we live, the houses are on acre-or-more lots and there are no fences. We live on a cul-de-sac on a mostly wooded 8 acre patch of land. Woods on three sides and we sit on a ridge that goes down to a hollow then up along another mountain. I was not used to that!
So you can understand how afraid I was of moving to the woods.
The invisible fence encompasses an acre, it actually goes through some woods, and training a dog to it is heartwrenching. I hate it. But...it keeps ours in...and considering that it keeps Yodel the nose in, it will work on almost anybody.
I would love to hear about Israel one day.
