When I pet another dog, my dog comes up and almost pushes the other dog out of the way. Also, if I am playing with her, and the other dog wants to play with her, she will growl/bark. Both dogs are over 10 years old. Help!
i would remove her from the room for a few seconds and repeat until she realizes that every time she growls that she is sent away. i would also add a word like stop and then remove her immediately. it should be easy to correct all you do is what you do and when she does what you don
