Hi,
We have 10 1/2 week old puppy. She is gorgeous! Very playful and loving, but a bit bitey ...we're working on it.
Anyway, from the second night, she was sleeping through from 10.30-7.00
No whining, no mess. We just thought we were very lucky. Yes, she was having a fair few accidents during the day, but to be expected. We were\are taking her out every 20 - 30 minutes and we're starting to read her signals. There weren't any initially. Again, all "normal" I would think.
However, the last couple of nights, she has been howling, on and off through the night and also is weeing and\or pooing in her pen! I don't think the neighbours will be inviting us over for dinner any time soon 
We have actually just had new floors put down, so I guess this must have something to do with it. She sleeps in the kitchen \diner and it was half carpet before. That's where she used to sleep, but now it's hardwood. She has a very soft bed, with a blanket, but obviously underneath is now hard...
Could this be why she's whining and messing? Do puppies tend not to like sleeping on hardwood floors? Should I just completely cover her penned area in blankets? Should I move her pen into the living room where there is carpet?
Any ideas much appreciated.
TIA
