Well, wasn't I feeling smug. Dpup is 5.5 months old, female golden retriever. She has always slept pretty well at night, usually last wee at 9 or 10 and goes through to around 7.
On Monday I forgot to close the stairgate and she snuck up and discovered we have an upstairs and she could go up there.
Every night since she has woken up in the night and grumbled then barked till I get up to let her out for a middle of the night poo and wee. 1am some nights, then 6 am again... 4am last night then 6 am again. Bah.
I'm knackered as I frequently can't fall back to sleep easily. On my own and kids too young to help during night.
How do I go about sorting this? She sleeps downstairs alone, always has. Was in a pen till about 2 to 3 weeks ago and now has run of (same) middle room at night. I don't think it's the pen going, but the fact she has clocked the existence of another floor of the house where her people go.
Otherwise well, well-excercised, eats plenty etc.
