Welcome to YorkieTalk! I got your private message about seperation anxiety. I would start keeping him in a certain area while you are gone, whether it's in the bathroom, cordoned off in the kitchen, wherever that you think is safe for him. Then make sure he has toys to play with, water and maybe even food. Try to give him things to focus on. Then start leaving for short periods of time and coming back to him. Praise him when he calms down and reassure him. He is probably stressing that you are going to leave him forever, so just think about that. He will adjust eventually when he realizes that you are here to stay
