Thanks for your replies and suggestions everyone!

Timber really isn't the type of dog that is easily confused by a change in her environment -- what really stressed her out was the change from having me with her 24/7, to barely getting to see me at all, due to my aunt moving, and then school and the bus schedule change. If the change does stress her out at all, I can cut out the weekends and just let her come over for a half day, like I would do on weekdays. I feel though, the if she is confused, it would be better than having her stuck at my aunt's all the time. When I had her she got 2-5 hours of running exersise everyday. Now they they have her, she gets two 10-20 min walks everyday. She has so much cooped up energy. She is tied up outside because they don't have a fenced yard, and she hates being inside unless I'm inside. I think that any confusion she would feel would be much better than the frustraion she is feeling right now.
