This spray will help deter males from your female dog while she’s in heat ("extinguish" it!) and also help the males not pick up their scent as much.

Instructions: Shake well.  Spray directly on to the female’s hind quarters and/or diaper.  For males, spray a bit on the tip of your finger and dab on the tip of his nose.  Reapply as needed.

This comes in a 1oz glass spray bottle

Ingredients: peppermint, eucalyptus essential oil.  Water
