Maybe all dogs can be difficult in their own ways. Jessie (my blue roan) never tried to get at the food compost bin (easy for her to open) and she knew what was in there - but after an op for pyometra she began barking several times a night. After a year of trying everything - sub milk tabs from vet, going down to her to comfort, going down to tell her off, not going down at all - it was no better and I was exhausted. Eventually much against my will I started to take her up to my bedroom and she slept on her bed on the floor - still woke 4 times a night barking but it was easier to calm her - she just seemed frightened. After a few months she began to sleep through and life was easier for us all.
It was much against my principles to have the dog in the bedroom but I needed the sleep and in the end I only had to stand up after 9 in the evening for her to be at the bottom of the stairs trying to persuade me to go to bed!
I think it is one reason I miss her so much since her recent death - we were together for nearly 24 hours a day and I am glad I gave her the comfort she needed. But I should add that she was quite happy to go to the local kennels so was still adaptable and happy to stay with others, just liked to be with me when at home. (Unless my son was home when she would switch allegiance!)
