The vet has eliminated a UTI so far and next step is internal investigation. She is not PG thankfully

as I live in a very rural area and thankfully can allow er off lead without the worry of other dogs.
I don't consider her as untrained as such as this is a problem with regards loss of control rather than a behavioural issue. With the volume of mess she does at night I think to crate her would stress her because she can't hold the wees and poos, they literally just happen - bit like incontinance I suppose
