I own one little diva, Tinkerbelle, she is 4 years old and she is my little love but can be a little terror. I am at work for 9 hours a day and for the first couple of years she did well. I went on vacation for two weeks and my brother dog and house sat. I didn't want her to be in unfamiliar surroundings. No she's not spoiled at all. Anyway after that she developed seperation anxiety, as my brother was with her 24-7. So now it is heartbreaking when I leave for work as she barks and actually cries when I leave. I feel so guilty leaving my little girl. I am currently looking for a sister for her.
It is a personal decision and I have made my decision for my girl and for me as well.
Good Luck
