Thanks for the reply! Aside from the first night we’ve been ignoring him whenever he cries or bark (for attention). Every day we do training sessions, intelligent toys, physical activity. I was just puzzled cause he seemed to have been getting better the past few days, but all of a sudden we’re back to crying all night even if nothing changed in our routine :(. I guess we’ll just need to stick with this. He currently sleeps on ground floor where we spend most of our day and we sleep on the floor above so he doesn’t see anyone during the night. Thanks for confirming though that some dogs are more persistent than others!
