Is this child abuse?

[AndiE]

In saying that though, I caught DS one day with the working dog training collar once, holding it against his tummy and pressing the button on the remote! He thought it was hilarious!

First I laughed when I read this, and then I've started to wonder if your fence WILL work like you hope it will. Sorry, don't mean to be negative ... but if he's the sort of kid who shrugs off injury/pain (my DS1 is tonka tough like that - nothing much seems to hurt him physically!) then a low volt shock may not be much of a concern to him. As I said in my previous post - good luck, this is a tough one!

ETA - should have added that it sounds to me like you've done your research well! Good for you : )
