i have to agree with joanne-v about giving up on her so easliy, i expect your parents were going to keep her just to help you out, something as simple as letting her sleep in the bedroom would probably have solved the night time thing, i know some people seem to find that a problem, but its really down to the individuals , i dont think tiring her out will do it as they just dont get tired like us . with 2 of mine i could do a 4 hr walk but 10 mins later they would be ready to go again ::)could you maybe do agility to mentally stimulate her .could there be a underlying medical problem here, i expect you have taken her to the vets ,sorry seem to be clutching at straws , but i do feel for you ,i really hope you can find a solution as they cant tell us what is wrong in their lives and its so hard to work it out sometimes,
