Jinka is my first Dobe. She is a great, wonderul girl age 2years and 3 months. Very well socialized to the community and has been pleasant with people. We have her out and about very often. Over the last few weeks with her age and maturity, she is getting more protective and watchful in our home. When someone comes up, she is no longer eager for them to come see her as when she was still "puppylike". She growls and barks with her hair up; it is scary to people who do not know her. I have always said, "That's enough, thank you," but that is not calming her from the behavior. This is the one place we have failed in our socializing with her because we rarely have a guest to our home, and as an adult, she does not know how to handle strangers coming in on her territory. And since this is a new stage for both of us, I am not sure what technique to use to train her so she knows it is good to do her protection job, but to stop and back off when I say. How did you train in this stage?
