Hi,
So I've already posted about this, but we thought we had it. We don't have it 
She never has accidents in the day. Never. It's only at night and I know she can hold it, because she always could before and was never desperate to go out in the morning or anything. I think she's just decided that it's ok.
She was ill and on antibiotics, so that would explain the initial set back. She got better and stopped doing it, then started, then stopped and has just started again! 
We thought we'd cracked it. Fed her a bit later, made sure she'd done a poo after that and if she hadn't in the garden, we'd take her for a walk. I scrubbed and scrubbed the carpet and febreezed it to get rid of as much scent of hers as possible.
We had 3 mornings in a row where we came down to nothing and then the last two, enormous poos everywhere!
Any tips? Desperate for advice. I don't want this to be a permanent thing... obviously. She's being spayed next week, so no doubt that will throw her too. Fun times! 
TIA
