Shadow is now 15 weeks (we brought her home at 11) and is having trouble sleeping through the night. We put her down around 11:30 and ideally would like her to sleep until 6:30. She has a pen area in the bathroom - where there is a cage (w/o door) for her to sleep and then an area for her to play and an area for her wee pads. Some nights are great - then others, like last night - are horrible. She barked and cried almost all night. We have a ticking clock, a talk radio, and a sock of ours for scent in her area. Lastly, she has a water bottle, but no food. Is this still normal at 15 weeks? Please help! We need suggestions...and we need some sleep!
