Having been to the Defense Language Institute for German, then transferred there, let me please tell you: It's a culture shock, but if you don't IMMEADIATELY start learning German, you will be absolutely miserable enough. It's a completely different culture and country (Their Kentucky Fried Chicken tastes like fish, because they feed their chickens fish meal), and you should prepare yourself as much as possible.
You must immerse yourself in the German language, like making a point of thinking in it as much as possible, and putting stickers on all things in your house, labeling them in the German nouns. TV is "Fernsehengeraete," (Far seeing machine) for example. Even with intense DLI training, and living there a year, it takes about 5 or 6 years to fully incorporate ones' self into another culture.
Plus, it's not a homogeneous society over there, any more, with MANY Turks, etc., "Illegal Immigrants," already crowding things out. You'd best research this well, in terms of getting a job, there.
If I were you, I'd leave the mutts with a family member back home...
Vielen Glueck!
