If it does take you have a guesstimate now how long and when your bitch is ovulating.Progesterone levels can fluctuate so it can be tricky,had a tie and no luck one stick with a bitch that comes in once a year.I would go with science if the male wasn't on my yard,thought about doing what ceaser did and said hell no wouldn't chance that.Hats off to ceaser the passion is real lol.
