Pet filters are unnecessary. Nowhere in the law does it say that you can prohibit a tenant from bringing a pet. So even if the landlord does not want you to bring your playful dog, he cannot forbid you. The only exception is when it is stated in the articles of the agreement of the Owners' Association. So you can ask about that just to be sure. Of course it is very different if your pet causes a lot of nuisance to the neighbors, then you may still have to leave the house with your pet after a long legal process.
