how old is the dog? Is she fixed? Are there male dogs in the area if she is not? Whats her breed? Is she left alone a lot? Is she bored? Or is she just trying to upset you? There are many reasons why a dog urinates in the house but this might be that the muscles around her bladder are weakening. That's why I asked her age also has she had large litters. If she is a young dog and there are no medical reasons why she would be doing this then you quick answer is, training, repetition, punishment(for most dogs this is a stern voice or quick movement with a growl NOT BEATING), and you being the one in charge at all times. Good luck I hope your faithful friend is okay.
