[Gracie2006]

I got Holly when Gracie was 18 months. I say give them each their own space, and let the older one get acquainted in his or her own time. Supervised play sessions are great. Be sure to give your older one every thing first. First to be loved, first to be fed, first greeting when you come home, first treat, etc. And then give seconds and thirds. Remember, puppies are rude and your older one might not appreciate being jumped on, chased, and otherwise "bugged". It is just like skin siblings sometimes. Buy everything in twos. You can give each the identical same thing and the puppy will want what the older one has. Don't force them on each other or force them to share or sleep together.
