Ok since the move Hannah has been having issues. I have tried combating these issues by keeping up with NILIF and more obedience everyday. She seemed to have calmed down with the growling and aggressive behavior and then this morning Mark walked out and she growled at him he said "no" in a stern voice and she kept growling at him. From the dog food forum I have found an article posted by Mordy that some dogs that have territory aggression caused by fear have hightened issues due to high protein foods. I was wondering if maybe I should try feeding her a lower protein food and keeping up with the NILIF and obedience. I try having Mark spend obedience time with her too but he's really busy with work and no he's doing side work so he's not home a lot. I want to get her in to see a behaviorist but it's expensive and we just can't afford it at this time. Does anyone have any suggestions on what we can do to help her. I don't know but I do think that the one night she had to stay with my sister in law and her family after the incident I think they may have hurt her in some way (physically). Could this be the problem?
