This is a fabulously simple and effective remedy for those times your dog meets up with a black and white 'cat' of the smellier persuasion (and no tomato juice is required).
1 quart hydrogen peroxide (3%, from the store)
1/4 cup baking soda (any brand)
1 tsp. liquid detergent (shampoo, dish soap, etc., to cut the natural oils in the dog?s coat)
Mix and apply. If you catch it before your friendly canine has rubbed it deep into his coat, you only need to wipe it on the surface of the coat. You can mix up a 1/2 batch if this is the case.
