Did you know that a bottle of peroxide, some baking soda and shampoo, applied immediately, works better than anything else? WAY better than Skunk off. Neutralizes the whole chemical reaction.
1/2 hour after bathing, and no smell. The dog probably was scrubbing his or her face immediately afterward the spray? Skunk spray is really hard on the eyes, the face, the poor nose. It's almost caustic, it burns, dogs rub and scrub their faces afterwards. Been there, more than once. My husband got skunked in close quarters (a duckhouse) stopping one from killing our duck on hatching eggs.
