What has everyone used for the pee stains on the rug? I have a spot cleaning machine, but sometimes the yellow stain remains. My new puppy has a couple spots that I cannot seem to keep her from going back to. I have read to use vinegar for the smell, but have not tried that yet. It is supposed to remove the smell so the dog cannot smell the spot anymore. I have tried Natures Miracle and numerous other products (I have a Yorkie who has peed for years until I got him a diaper) and nothing keeps the dog from going back. Short of getting all new carpet, does anyone have anything that has worked? My new puppy seems to be slow to learn. Unless she is in the room with the litter box (and even sometimes if she is) she will use the carpet. I had a litter box in the kitchen on the border of the livingroom/kitchen and I moved it because I really want her to go in the laundry room, that was only temporary till she got bigger and could FIND the laundry room. Well....she goes where the box USED to be. It is very frustrating...and my carpet is getting ruined. Any help with cleaning advice and also training advice would be greatly appreciated. She is three months old and we have had her for four weeks.
