Honestly, I think the best approach is to NOT make a big deal about the move. Dogs adapt very well when their family members are secure and confident. I suggest moving Mickey's bed, toys, food bowls, etc. to the location in the new home where he will be using them. Bring him home calm and confident and show him where his things are and then give him a chance to explore. If he is outside potty trained then be sure to show him the doors and take him out extra to help avoid accidents. If he is indoor potty pad trained then be sure to remind him where his toilet area is and do lots of praise when he "does his business" in the right place.
Once again, it is vital that you have confidence in Mickey that he can make the transition seamlessly to his new home. Any stress on your part will be relayed to hi through your body language and scent.
I take my two precious yorkie girls to my daughters, on vacatiton, etc. and they never ever have problems, but I believe in them
