Ram shield?

[ledel]

I remember a little while ago some talk of a ram shield. I wanted to know if it was ever tried and if it was effective. I would like to gets kid to start training so when my current pack goat gets to old I'll have another ready. The Only problem is that she is quite aggressive especially to smaller goats she is really only good with big Nubians like herself. So I was thinking this may help her get used to the new goat and not hurt it.  Thanks!
