We have 3 year old Cavoodle female. She is house trained during the day however the night is a different story.
Our back door has a dog door so she can come and go as she pleases. During the day she goes out and we have no problems. The problems arise once we all go to bed at night. Every morning the dog has peed in the loungeroom. I got rid of the carpet in the loungeroom so there is no odour, we have had new flooring laid which can be mopped and I use Urinefree so there should be no scent left. The wee's the dog does are large puddles so I don't think it is her marking territory.
It's crossed my mind that the dog may be scared of the dark but she's happy to go outside and bark at the neighbours cat at night.
Any idea on how to stop this or what might be the cause?
