The quantity of chlorophyll to be given depends entirely on the size and weight of the dog. Directions are enclosed, and the owner of each dog must work out what that particular dog needs. The substance is quite harmless, so no one need be frightened of giving an overdose.
It is always helpful to wash the bitch’s vulva two or three times a day with a chlorophyll solution. If possible, exercise her away from your own premises. I usually take my bitches in the car some distance away before letting them run; thus if there were any scent to be picked up, it would not lead the male dogs to my house.
Most people want to know when to start dosing their bitches with chlorophyll. The answer is: as soon as you notice the swelling of the bitch’s vulva and discharge of blood from the genital passage. The period of heat varies vastly in bitches, but nine to fifteen days is about average. Some bitches come in heat only once a year some as many as four times a year; the greatest number to do so twice a year. The bitch is ready for mating as the discharge lessens and she stands with her tail turned sideways. This is the time when, whether you are using chlorophyll or not, I recommend careful isolation from any male dog.
