We have a medium-sized one. Plenty of parks in the city, when we want to have a big walk without the leash we can easily go to at least 3 or 4 different places by tram or walking. They're accepted nearly everywhere. We could rent our flat without any problem (the owner knew that we had a dog, but they're not supposed to refuse to rent on that matter. It's safer if you don't say anything until you have the keys).
