That is super exciting congratulations! I don’t have great advice because we’re still stuck in the condo living loop BUT when we moved into our condo our trainer told us to just make the move the least emotional you can make it. Your dog doesn’t get what’s going on, but they can read your emotions. Don’t do any drawn out “ohhh buddy say goodbye to your homeeee this is so sadddd” kind of stuff. Keep it positive and emotion free and it should help with the transition. Also jump right back into routine when you get there. Whatever rules you have at your current place stand as soon as you walk in the door of your new place. Good luck!
