Hi Rona,
being a vegetarian restaurant I wouldn't consider the "Karma" as dog friendly
...
Anyway, as Ina already wrote especially in our area I hardly know any restaurant or pub where you can't take your dog regardless what breed.
But the the same goes more or less for the rest of Germany.
I made the same experience in France, Austria and the Czech Republic.
Last year we were with 52 dogs (all kind of breeds and 5 or 6 wolfdogs) in a restaurant after a hike in the mountains.
