Works excellent... Toothpaste is the way to go.
I have three labs who regularly meet the skunk under the pear trees in the fall. I tried tomato juice and store bought remedies but they did a partial job and left a residual odor that recurred every time the dogs got wet. A friend recommended toothpaste. You squeeze a tube into water, mix well and wet them down with it. I left it on for a bit and worked it through before rinsing them off. It worked like a charm and no residual odor.
