I have found with Gracie that each person she comes in contact with must show her that she is not the boss. When she was a puppy she was very aggressive. She was typical terrier wanting to dominate everyone and every thing. I worked with her a lot and she became very obedient to me BUT I would see the same dominate characteristics come out all over again as soon as someone else entered the door. I could stand there and tell her "NO!" and she would not listen until I pulled her off the person she was jumping on.
I have had to ask people to please not let her jump or be pesty. I even had to put her harness on her when people came because she would be so naughty. It's like the training process had to be done by each individual. I know what you are saying. You are going to have to have your mom learn how to talk to your dog. They notice a person's energy level and if she is not using the same energy as you he probably is not going to respond as well.
Gracie is much better now. She still gets excited with certain people but she knows her boundaries. It took time and training though. |
