UPDATE: Since the "Bone Episode" I gave up on the idea that I was going to become through physical dominance of my pup. [My breeder had suggested training a la Cesar's Way] I was never 100% comfortable with this and my girl must have sensed it because she was not responding well at all. I began listening to my gut, along with some friendly advice from this forum and my new trainer. I had trained our last Rott with no problem [she was truly amazing and one of best friends ever], why shouldn't I use the same methods with this one.

I started with the treats, praise and lots of repetition. The change has been dramatic. I think today was a real benchmark day. We treated her to a marrow bone. Not one growl, gripe or guard. When we talked to her she would look up and even left it a few times to come over for a pet. When it was time to put the bone away one "off" and she gave it up with no problem at all. All this progress without one scruff shake or alpha roll. Just one more example that positive reinforcement is very effective.

Thanks everyone for your input!
