By your own admission, the biggest problem is that you're not experienced enough to handle the situation. And I agree with you! A more experienced person to deal with him is definitelty in order, whether you have a friend or have to pay a trainer. I also agree putting him down isn't an option. If you truly can't hire a trainer and /or have more surgery on the fella, then the next best thing is to arm yourself with knowledge. I like the Clinton Anderson DVDs on gaining respect. Of course, they're expensive too but you can rent them at a fraction of the cost. The only DVD rental companies that I know of presently is giddyupflix.com. Above all be safe, don't overextend yourself and realize if/and/or when the situation calls for you to throw in the towel! Good luck.
