1/3 cup ethyl rubbing alcohol
1 drop liquid hand soap (plain, unscented)
3 teaspoons citronella essential oil
2 teaspoons camphor oil
2 tablespoons mineral oil
In a small bowl or jar, add ethyl rubbing alcohol and camphor oil, gently stirring to combine. Then add citronella, continuing to gently stir. Then add liquid hand soap and mineral oil. Pour liquid into a small spray bottle (you can find them in the garden supply area, or smaller travel-sized ones in the beauty section).
To use, spray mist your dog lightly, avoiding the eye area, and any areas of broken skin (ie. from previous bug bites that are hot spots).
