hotels in Germany that welcome dogs

I can't imagine it here in Melbourne - hotels welcoming dogs as paying customers. In Berlin these hotels exist - canine visitors must be accompanied by a human, of course. Here's the site, Gridskipper where I came across this surprising information. Though perhaps I shouldn't be so surprised. I've stayed in Germany a number of times - on two occasions for some months - and I remember I was taken aback to see dogs in restaurants. In fact, seeing I was PDO at the time (pre-dog-ownership) I didn't like the presence of dogs.
Not sure what I think about it now...

I presume Gridskipper has done research. When I clicked on the links for the hotels themselves I didn't find any information about dogs being welcome, but I guess they might not want to actually encourage people to bring dogs!
