Hi, I'm after advice. I have a four month pup very clingy which puppys are. I have read crate training. He will gonin crate at night hates door closed. He will sleep in crate as long as someone in room. During the day if I leave room He barks non stop even if left for a moment while I go to bathroom or in the bath. If I go upstairs to hoover same issue. I would like advice firstly how to get him to sleep on his own. I cant sleep downstairs for ever. Also at some point he has to be left alone. Currently if I go shopping I have someone sit with him. I thinks it's more of an alone issue.
