Early hours of this morning my dog barked and was mooching about (actually quarter to 3) so I got up and he was desperate to go outside, when he did he was busting for a wee, but when I looked at his bed he had wet his bed also.  He is 14 months old now, this has happened once before about two months ago.  I always thought that they wouldn't wet their own bed.  He had been out for a wee at 11pm when we went to bed.

They won't normally so this sounds like it needs chacking at the vets.  He could have an infection.
