My doodle, Emma, has just recently started growling and acting protective of me when we attend training classes. It was so bad today, I was so stressed out that I had to leave. We were there less than 10 minutes and she was growling and lunging at the neighboring dog. This has happened a couple of times before, but it seems to have gotten worse. The first time it happened I took her to "play care" at a local training facility to see if this behavior was something we had to work on. She had a wonderful day and showed no signs of aggression. Of course, I was not there. I have noticed from the last three training classes she is behaving this way when I am around. I am coming to the conclusion that this is a protective response for me. I really don't know what to do. The girl in charge of the class is going to call me tonight to set up an individual session for the class we missed, but my main concern right now is the growling and lunging at the neighboring dog at the class. Is there something I can do? This is just a recent behavior and Emma is now 2 years old and we never had this problem before.
