If a neighbor is bitten by a dog while entering your house without permission,?

can the landlord tell you to get rid of the dog or he will evict you? There is nothing stated about any pet rules. The neighbor is trying to sue but the hearing is not for a few more weeks to even determine if the dog is to be considered dangerous. The upstairs neighbor has a dog from the same litter as this one and he isnt being forced to give it up. The neighbor opened the door and walked in to the apartment knowing there is a big dog inside...and then complained when the dog bit her.
