Posted on here a few months ago about leaving him and the advice was great- to get ready to leave then leave for a few mins and build it up. Have been doing this every day for over a month now and no progress.
He will be five months next week and has still never been left alone for longer than ten mins. When I need to go somewhere without him my brother dog sits. When I wait outside he whines and barks constantly, takes no interest in the huge variety of toys and treats I've offered, feel like nothing is working.
Is it terrible that at nearly 5 months old he has never been left alone? Is this likely to cause more separation anxiety than it would if I just left him to bark it out? Can't stand him being stressed and would feel so guilty leaving him but not sure if it would be better for him in the long run?
