That's what I'm afraid of when I go to stay with my aunt when my cousins need me. I don't want Shadow to think I have deserted her. She is now use to sleeping in the bathroom and knows what "Time for bed" and "get in your bed" means. I can't wait till she is fully housebroken though. There are several good kennels in the area for when I go to Aiken, but that is only for overnight.
My dogs would not eat, would fake illness, and come home depressed as hell. Going away for two weeks was devastating for them. My cats only get mad and that never lasts long.
