Having a relapse with poop

Hi, my beau is 16 months old now and was perfect at waiting to go out for a poop! Now all of a sudden she is making a mess in her crate every night.
Can anybody help with what to do?
I'm never cross with her as she looks so ashamed when I let her out.
She doesn't eat after 6:30pm she's walked every evening and does her business while we're out, she's even tried coving it with her blanket bless her.
We let her out every night before bed so not sure what to do! Any help gladly received,

hiya they can display unusal behaviour at this age is she going through the teenage phase perhaps their behaviour can all off a sudden change. i would just take her out 2x before bed bless her.

She knows she shouldn't so I wouldn't panic too much. As Crystal says, let her out again right before bed, with time a routine will emerge and this will pass.

Remember to clean up any mess with a deodorising cleaner as they tend to go where they've been before.
