I have 2 dogs that are potty trained but they do mark over each other on the walls, chair and table legs. They will even mark the area rugs that are behind our backs while we are sitting watching TV. So I don't see it when it happens. We finally got new area rugs that cost a few hundred $$$. So I want to make a repellent/deterrent and get ahead of the game. The Natures Miracle No More Marking does NOT work. I wondering if I mix some white vinegar with water, citrus oil and kiwi oil if that may work? Has anyone tried something like this? I am trying to find a great homemade blend of essential oils I can mix in with the vinegar to help curb the desire to mark. Any help is appreciated. TIA
