Adopted my lovely 4 old bichon 3 months ago. Happy little soul- loves people...and me. Can't get him out of the bedroom at night to sleep independantly either downstairs or on landing. He has a crate downstairs that he'll use sporadically to hide high value treats in and occasionally snooze but his separation anxiety is off the scale. I also can't go out without him barking his head off but the sleeping is time critical as I'm off on holiday in October and he's booked in to the boarders where he attends occasional daycare. He's failed one sleep trial by waking and barking in the early hours (admittedly I probably tried it too soon) so he will have one more chance before we go away to show he can settle overnight. So far I've tried the leave and go back like you do with babies, new bed and high value treats, longer walks, creeping upstairs without him. What has worked for you?
