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
