Dana,
I believe you have done everything in your earthly power to do right by this dog. You have a fantastic trainer and you have unearthed all possible solutions. Outside of your own heart and mind you also have it on very sage advice about his temperament and what he is capable of doing. It is the most difficult decision to make - to have to play God. However a good Rottweiler does not exhibit the signs and behaviors you're describing in Santo. Regardless of how well he was raised and trained. Someone made the analogy that Jeffrey Dahmer also had an ideal childhood, look what he grew up to be. Some living creatures are not wired right.

So sad this story, such a beautiful boy and so young. Send him home with all the love in your heart and peace knowing you are doing right by him.

My thought and prayers are with you.
Catherine
