How do i get rid of skunk smell without making a mess?

On the dog or on the house? For a pet, the mix that actually works is 1 litre of 3% hydrogen peroxide, a quarter cup of bicarb and a teaspoon of washing up liquid. Rub it into dry fur (don't wet them first), keep it away from the eyes, rinse after five minutes or so. Mix it fresh and bin what's left - never put it in a closed bottle, it builds up pressure. It can lighten a dark coat slightly. Tomato juice just masks it for a few hours.
