I am assuming Fanci is a Rottweiler.

Many 'trainers' have had negative experiences with Rotts, and therefor have an attitude towards them. I just came from a very expensive and sobering Obedience Seminar where I experienced this kind of prejudice.

I have to ask, what was this trainer doing to Fanci that made her growl? And was it a warning type growl or a vocal type growl? How did the trainer address it? Additionally, what circumstances did Fanci attempt to attack another dog? Were the dogs playing or moving about??? How did the trainer handle that?

You are being a responsible Rottweiler owner by taking Fanci to obedience classes, crating her when company is coming, etc. I would venture to say it is your trainer that failed in not addressing the certain drives Fanci possesses. I'm not so sure you need a behaviorist as much as you do a good trainer!
