18 month old pup always slept in our bedroom on trainers advice. Toilet trained late. Peed on my bed a few months ago just before bedtime just after being taken out. Figured she was just over excited and was more watchful. Couple of days ago she peed in my bed with me in it! She has been banished to downstairs. She has coped really well but is scratching door at 4.30am then 6am then we get up with her. Is there any way we should deal with the scratching? Hate to think of her being distressed but starting to suffer with broken sleep patterns.
