Thanks for the replies. Fanci has been with me since 8 weeks old. She is now 1 1/2 years old. She has a strong working background with many titled schutzund (sp?) dogs. My trainer did admit he thought her behavior was due to genetics and wasn't quite sure how to handle her. He let me do all the handling in class.
Most of the dog aggression incidences happened during free play time (the first 10 minutes of class). However she has been in two dog fights at my home where I take care of other dogs for rescue work.
The trainer referred me to another trainer that deals with aggressive dogs. I will contact her but was also wondering if a behaviorist should be the next step.
Also, there is a working dog club in my state; would it benefit me to talk to this club and ask them about her issues?
