I realize I'm coming to this thread late, but wanted to reinforce the idea that your adoption group will be a fantastic resource for you in these early stages of GH ownership. I am assuming you probably adopted through either GPA-MN or Northern Lights. Both are wonderful groups with very supportive and dedicated volunteers. Your first contact should be your adoption rep. And if you feel you aren't getting the help you need there, or simply want more opinions/advice, you can certainly turn to either (or both) of the local group email lists.
Greytalk is also an outstanding resource, and you've received a lot of really good advice here, but I want to make sure you're getting all the local support you need as well. Sometimes being able to meet up with volunteers and other local GH owners in person can make a world of difference in helping you and your dog adjust to this new life together.
I see you intend to go to Meet & Greets with your pup. Great idea! I would also suggest, if you're available, joining any group walks in your area. GPA-MN has group walks every week, weather permitting, at Lake Harriet in Mpls, and Como in St. Paul.
I am an active volunteer locally, and I am always happy to help new adopters in any way I can.
