My two cents is that maybe you didn't use very much of it. To cover a whole living room, especially a dirty one that reeks of dogs, I would put maybe a cup of OBAN into a gallon of the cleaning solution that I was washing the rug with. Then I would probably spritz some into the air after the washing was all done.
If the odor was originating from urine, Nature's miracle works well, if you can identify the spots.
If the urine is widespread, forget it... You need the restoration service that Mark mentions.
