My in-laws have been renovating a house they own on their family farmland and have come up with this great idea to install an electric fence around the property for our dogs. My husband and I are really nervous about this though because a) we don't want to shock/hurt our dogs and 2) we're afraid our high-strung dogs (Australian Shepherd and Australian Shepherd/Border Collie) will go straight through and not really care that it exists.

Has anyone used an electric fence successfully for your dogs?

(Also, we know many of the pros/cons - i.e., that it doesn't keep other animals from getting inside the fence, and we would NEVER use it when we were not outside with our dogs - but we're still nervous and looking for some anecdotes!)
