Hi,
Advice please! Not sure what's gone wrong, but the last couple of mornings we've come downstairs to several piles of poo
She was a good puppy with training, with the odd set back, so it's just not like her.
Is it common for them to still have the odd set back? Or could she just be getting comfortable with the idea of using the living room as a toilet? 
She recently had a bath (first in a month!) and then we threw her old bedding out, got her a new bed and deep cleaned everywhere, so could she perhaps be marking her territory?..
TIA
