Lots of changes coming up

I've been wondering if dogs have a hard time getting used to new situations as much as people do (or I do). We're going to move to another city this fall, new places, new apartment, new neighbors... Do dogs tend to get anxious the first few days? Has anyone been through something similar? And if so what can I do to avoid my dog getting nervous about all these changes? On top of that we're also flying this summer to see my family who he has never met, and they have another dog. I feel like its so many things at the same time! Even though Loopy isn't a nervous dog at all and he's used to people and other animals. I take him everywhere he's allowed to go...
