We were in an excellent routine with our pup who slept in an unlocked crate in the kitchen from 10-7/7.30 every day. Then we went on holiday and she went to kennels and since being back she just won't go to sleep and whines and barks - we've now had to start locking the crate as she is destroying the door - and when she does sleep she then wakes at 4am/5am - whenever she feels. We tried ignoring this but don't think our neighbours are too pleased and we have 2 little ones that need to sleep. Tried more exercise, tried leaving radio on and don't know what to do.......sleep deprivation is killing me! Please someone give me a miracle solution!
