Mother to Daughter domination
I am new to the forums but have an issue I need help with. I have a female gsd who 3 years old and one of her puppies who is now 1. Recently, the mother has become dominant over the daughter. She never gets overly aggressive, but she will stand over her daughter and make a growling noise(although her teeth never show). The daughter dog always bows to her and just sits there while this goes on. When I yell at the mother dog to stop she just walks away and they both go about there business. This doesn't happen all the time, as they sleep in the same room(even next to each other), can eat and drink out of the same bowl, and go on a walk together. I am wondering if I can do anything to prevent this behavior?
