You will need somebody to come over on a regular basis while you are at work. 9 weeks is far too young to leave a puppy alone. My puppy is 6 months now and the longest she is left is 1 or 2 hours maximum. I am lucky because I work nights and am home during the day so our puppy is never left alone for long periods.

Ask your parents to stay with her for a while to play with her and give her some motivation. She will get extremely bored if she doesnt have anything to do for such a long time and could end up wrecking her crate or your house.
