Baking soda. Sprinkle some on there for a while to soak up anything that is wet and then take a vacuum cleaner with a brush attachment and if there is anything left over try taking a white towel with just a little bit of water (fine mist spray) and try rubbing it out. After you get it all off, take a soft bristle toothbrush and brush the suede back to the way it was. To prevent that from happening again, take a fine mist spray bottle and put about 1/3 vinegar and 2/3 water and spritz the couch down with it on occasion. Something about vinegar, dogs don’t like.
white vinegar water will get rid of the smell and keep puppy from going there again… oxyclean will get the spot
