I think her new aggression is due to the fact that I recently graduated school and started working very long hours. During the week I am only home long enough to eat and sleep. On the weekends I am busy getting ready for the next week.
I used to be able to let her roam the house and on warm days let her spend the whole day in the back yard but I am not home to check on her anymore.
I think it might be better for her to go to someone who can give her the freedom and attention she need. I am in Southern California north of Lancaster. Is there anyone in the area willing and able to give her the proper care? I don't want to give her to just anybody.
