My 5 monfh old Labrador pup is barking intermittently every hour or so from 4am and it's driving us mad. She doesn't need the toilet (runs away from the back door when I open it!) and will settle if I call down to her "back to bed" from upstairs but within an hour she's at it again. We did try crating her but the barking was worse, she was much happier roaming free and snuggling next to her older sister (never barks and sleeps all night!) if I try to bring her upstairs to be closer to us she seems to get spooked and aways does an accident on the carpet so we don't really bring her upstairs. I'm soooo tired. What can we do? I think she just wants attention / reassurance that we're there. Help!
