My living room started to stink like dog. I am clean, I vacuum and sweep etc...keep my house clean. So, I noticed it was around the couch where it was stinky. I couldn't see anything, I have neutral colored carpet and fabrics. So, I got a black light at the pet store. Oh man, can I just say GROSS!!!! I could actually see the patch on which he had been marking. Oh yucko. I got some urine eating enzyme de-stinkifier stuff and used it on the area. Has anyone ever used that stuff and if so, what were your results? I'm so grossed out, I want to cry. I want new carpet. I want tile floors and plastic furniture. I want to cry.
