My husband picked up a blacklight this evening and we checked the carpet all over. Let's just say that Sprite was a busy little girl. Even after I steam cleaned the carpet the black light still showed up all the stains. I then used Nature's Miracle on every stain just to be sure but they still showed up under the black light. Apparently the stains will show permanently but will not look as bright green as they did before. We then went through the house and surprise surprise, we found another little area that Sprite was using in the hallway upstairs that we didn't have a clue about. I was shocked because we never caught her doing anything there and didn't see anything with the naked eye. I've been steam cleaning all evening and little Sprite doesn't know it yet but she's going back to square one with the house training. She's going to be on her leash again inside until she can be trusted
The suggestion to use a black light was great. Thanks so much!!!
