crate training-barking too early
 

I have been crate training my six month old Pomeranian, Meesha. She used to sleep til the alarm went off at 6:00am, but is now staring to bark beteen 3:00am and 5:00am. I don't know why she is doing this or how to stop her. I am a Monday to Friday worker, and I can't think of anything that has changed in her or my routine. Help!!:confused:
